Silica Brick Industry Policy Updates in 2026

In 2026, domestic regulatory requirements for the refractory materials industry were further refined, with updates to environmental protection, energy‑consumption, and ** standards at the silicon brick production stage. The relevant new regulations have already been officially implemented in numerous industrial provinces across the country.

Implementation Status of the New Environmental Protection Regulations for the Refractory Materials Industry

The 2026 revised “Emission Standard for Air Pollutants from the Refractory Materials Industry” has officially come into effect, mandating that the calcination stage of silica brick manufacturers reduce particulate matter emissions to below 10 mg/m³—a 50% tightening compared with the previous standard. At present, leading domestic silica brick producers that comply with the new regulations have already completed upgrades to their associated environmental protection facilities, while smaller and medium‑sized production capacities are being phased out.

Interpretation of Support Policies for the High-Value-Added Refractory Materials Industry

In 2026, industrial and information technology authorities in many regions will include high‑end low‑porosity silica bricks and specialty high‑temperature silica bricks in their advanced manufacturing support catalogs. Eligible R&D projects for silica bricks will be eligible to apply for an R&D investment subsidy of up to 30%, further accelerating the pace of technological advancement in the industry.

News on Market Supply and Demand Changes for Silicon Bricks in 2026

In 2026, the overall silicon brick market will maintain a tight supply‑demand balance. Downstream demand is undergoing a pronounced structural upgrade, with overcapacity in standard, low‑end silicon bricks and a noticeable supply gap for high‑end, customized products.

Downstream trends in glass and coking industry demand

In 2026, newly added capacity in the float glass industry will gradually come online, and with a large number of existing coke ovens entering their second round of maintenance cycles, overall annual demand for silica bricks is expected to rise by approximately 7% compared to 2025, with demand for high-end silica bricks used in long-life kilns increasing by more than 20%.

Capacity Adjustment Status of Leading Industry Manufacturers

By 2026, leading manufacturers of silicon bricks are expected to phase out low-margin, standard‑grade production capacity and shift toward high‑value‑added, customized product lines. Meanwhile, Zhengzhou Jinshan Refractories will commission a 20,000‑ton‑per‑year specialty silicon brick production line in the second quarter of 2026, enabling it to swiftly meet diverse downstream supply requirements.

Research Progress on the Technological Upgrading of Silica Brick Production**

In 2026, the industry achieved numerous breakthroughs in performance optimization research on silica bricks, with several new processes having transitioned from the laboratory stage to mass production, significantly enhancing the overall service performance of silica bricks.

Release of Research and Development Achievements in Low-Porosity Silica Bricks

The new low-porosity silicon bricks slated for release in 2026 by leading R&D institutions in the industry achieve an apparent porosity of less than 20% through optimized raw-material gradation and refined sintering processes, while delivering erosion resistance that exceeds that of conventional products by more than 30%.

A new process for the recycling and reuse of waste silica bricks has been implemented.

In 2026, the closed-loop recycling process for waste silica bricks was officially put into mass production. After sorting, purification, and reprocessing, the resulting recycled silica bricks achieve performance levels exceeding 95% of those of new products, while reducing production costs by approximately 25% and significantly cutting solid-waste emissions.

The current standardized mass-production process for the new-generation optimized silica bricks is as follows:

1. High-grade quartz sand with a purity of 98% or higher is selected as the core raw material.
2. Adding a composite mineralizer optimizes the sintering process and reduces internal cracks.
3. A gradient heating firing process was employed, with the temperature held at 1450°C for 48 hours.
4. Before leaving the factory, the finished product undergoes three rounds of performance sampling inspections to ensure that all specifications meet the required standards.

According to an industry report published in 2026 by the Refractory Materials Industry Association, upgraded low-porosity silica bricks can help reduce the overall energy consumption of downstream kilns by approximately 8% and lower total operating costs by more than 12%.

Typical Application Scenarios of Silicon Bricks** Dynamic

In 2026, the application scope of silica bricks in high‑temperature industrial settings will expand further, with increasingly diverse customized requirements across various downstream industries and performance outcomes that consistently exceed prior industry expectations.

The service life of silica bricks in float glass furnaces has set a new record.

A float glass furnace commissioned in 2014 by a leading domestic glass manufacturer utilizes an upgraded, high-purity silica brick lining. As of 2026, it has been operating continuously and reliably for 12 years—far exceeding the typical eight-year service life of conventional silica‑brick furnaces—and has significantly reduced the plant’s major overhaul costs.

Demand for customized silica bricks for coke ovens in the coking industry is on the rise.

In 2026, newly built large-scale intelligent coke ovens will widely adopt custom‑designed gradient‑performance silica bricks, with each furnace section equipped with silica brick grades tailored to its specific operating conditions. As a result, the overall design life of these coke ovens will be extended to over 40 years, fully meeting the diverse requirements of intelligent production and operation.

A Practical Guide to Avoiding Pitfalls When Buying Silicon Bricks

In 2026, the quality of silicon brick products on the market will vary significantly. To procure cost-effective silicon bricks that meet their specific application requirements, users must adopt scientifically sound evaluation methods during the purchasing process.

How to Identify Low-Quality, Non-Compliant Silica Brick Products

Low‑quality silica bricks commonly suffer from insufficient quartz sand purity and inadequate firing time. Users can assess whether a product meets the required standards by measuring its silicon dioxide content and its load‑softening temperature—two key parameters. Products that fail to meet these criteria are not recommended for purchase.

Key Criteria for Selecting a Reliable Silica Brick Manufacturer

When selecting silica bricks, users should prioritize reputable manufacturers that hold full‑process production qualifications and can provide third‑party performance test reports. Zhengzhou Jinshan Refractories, with over a decade of experience in producing refractory bricks and castables, offers complete quality traceability documentation for all its silica brick products.

Industry Development Trend Forecast for Silicon Bricks in 2027

Based on an assessment of industry trends through 2026, the silicon brick sector is expected to advance along two key axes—green and low-carbon development, and performance enhancement—while overall industry concentration is set to increase further.

Green and low-carbon production will become the industry’s core entry threshold.

It is expected that by 2027, the entire industry will have established a carbon‑emissions accounting system for the silicon brick production process. Production capacity that fails to meet low‑carbon emission standards will be phased out, and the industry’s overall level of green manufacturing will reach a new height.

The market share of high-end, customized silicon brick products continues to grow.

By 2027, the market share of high-end custom silicon bricks is expected to rise from the current 22% to over 30%, with scenario-specific, tailor-made silicon brick products becoming the market mainstream and significantly enhancing downstream users’ overall experience.

Overall, in 2026 the silica brick industry is at a critical juncture of high-quality development, with new technologies and products continuously emerging. Downstream users can select well‑matched, certified silica brick products tailored to their kiln’s specific operating requirements, thereby reducing overall operating costs.
