Silica bricks are acidic refractory materials made primarily from silica and are widely used in various high-temperature industrial kilns. As a category that has drawn significant attention in the refractory materials sector since 2026, industry associations, manufacturers, and downstream customers have recently been releasing copious amounts of relevant information. Zhengzhou Jinshan Refractory Materials Co., Ltd., a specialized manufacturer with many years of expertise in the R&D and production of silica bricks, continuously updates its official website, www.zz**refractory.com, with the latest industry developments for users to access.

Summary of Industry Policy Directions for Silicon Bricks in 2026

The entire production and manufacturing chain of silica bricks has been incorporated into China’s domestic industrial low-carbon management system as of 2026, with relevant policy requirements being progressively implemented, thereby providing clear guidance for the standardized development of the entire industry.

Requirements for Low-Carbon Management in the Refractory Materials Industry

The 2026 revised carbon‑emission accounting standard for the refractory materials industry has officially come into effect. Under this standard, the per‑unit‑product carbon emissions for silicon brick production are required to be reduced by 12% compared with 2025 levels, and companies are encouraged to replace traditional fossil fuels with clean energy. Eligible technological upgrade projects may apply for special subsidies from local departments of industry and information technology. Industry insiders generally believe that this policy will further accelerate the pace of technological upgrading among leading silicon brick producers.

New Regulations on the Compliance of Silica Brick Production Capacity

Starting in 2026, all newly built or expanded silicon brick production lines will be required to complete public disclosure of capacity replacement. Small, scattered, and poorly managed production facilities that fail to meet environmental protection and energy‑consumption standards will be strictly prohibited from entering the market. This measure will further optimize the supply structure of the domestic silicon brick market and enhance the overall quality of its products.

Progress on the 2026 technological iteration of silicon bricks**

In 2026, research and development in silicon brick‑related manufacturing technologies continued to make breakthroughs, with several innovations previously confined to the laboratory now achieving mass production and practical application, resulting in a marked improvement in product performance.

Achievements in the Upgrading of Low-Creep Silica Brick Production Technology

Leading manufacturers have generally completed the formulation optimization of low‑creep silica bricks. By incorporating a small amount of composite mineralizers into the raw materials, the product’s high‑temperature creep rate at 1400°C can be kept below 0.2%, making it well suited for extended‑duration continuous high‑temperature kiln operations. The low‑creep silica brick products under Zhengzhou Jinshan Refractories have undergone multiple batches of field testing in actual kilns, demonstrating consistently stable performance.

Breakthrough in Technology for Recycling and Reusing Spent Silica Bricks

The newly implemented harmless recycling process for waste silica bricks, introduced in 2026, enables used silica bricks removed during kiln dismantling to be sorted, decontaminated, and reground. These recycled materials can then be incorporated as a raw material at a 30% substitution rate into the production of new silica bricks, significantly reducing raw-material costs at the manufacturing stage while aligning with low-carbon and environmentally friendly development goals. The specific operational steps are as follows:

1. The recovered waste silica bricks are sorted and graded according to their degree of damage and silicon dioxide content, with substandard pieces containing substantial slag and impurities removed.
2. Surface‑bound harmful impurities are removed by high‑temperature spray cleaning, followed by crushing and grinding to the specified particle size.
3. After being mixed according to the specified formulation and with new raw materials, the product proceeds to forming and firing. Once it passes inspection and meets the required standards, it can be released from the warehouse as a finished product.

Silica Brick 2026** Market Supply and Demand Data Analysis

Based on publicly available industry statistics for the first half of 2026, the overall silicon brick market has maintained a steady growth trend, with no significant fluctuations. The key relevant data are summarized in the table below:
