In 2026, new projects in domestic downstream high‑temperature industrial sectors—including steel, glass, and photovoltaics—are expected to come online en masse, directly boosting demand for silica bricks by approximately 7.6% year over year compared with 2025. Moreover, the growth rate of demand for custom‑made silica bricks will exceed 15%, significantly outpacing that of standard industrial‑grade silica bricks.

2 Trends in the Upgrading of Mainstream Silicon Brick Production Technologies

By 2026, the pace of technological advancement in silicon brick production has markedly accelerated. Long-standing industry challenges—such as excessively high porosity and insufficient load‑softening temperatures—have been effectively addressed through targeted technical optimizations.

2.1 Popularization of Low-Porosity Silica Brick Preparation Technology

By optimizing the raw material particle size distribution and adjusting the sintering temperature profile, mainstream manufacturers can now maintain the porosity of silica bricks below 18%, a reduction of 3 to 5 percentage points compared with conventional products. Consequently, the materials’ resistance to chemical erosion has been significantly improved, and their service life has been extended accordingly.

2.2 Implementation and Application of Green, Low-Carbon Production Processes

Many leading manufacturers have already completed upgrades to their kiln waste‑heat recovery systems, utilizing the recovered heat in the raw‑material drying process. As a result, specific energy consumption per unit of product has decreased by approximately 20% compared with previous levels, fully meeting the industry’s carbon‑emission control requirements.

3. Development Trends in Core Downstream Application Scenarios for Silicon Bricks

In 2026, the downstream application landscape for silica bricks continues to expand. Beyond the traditional domains of coke ovens and daily-use glass furnaces, the share of emerging applications—such as photovoltaic glass production and incineration of industrial solid and hazardous waste—is rapidly increasing.

3.1 New and upgraded coke oven projects drive demand growth

In 2026, more than 30 large-scale coke oven construction and renovation projects are expected to be commissioned in China’s metallurgical industry. Each such facility will require over 20,000 tons of silica bricks, providing stable underlying demand and ensuring that the share of silica bricks used in coke ovens consistently accounts for more than 60% of total demand.

3.2 Increase in the Proportion of Silica Bricks Used in Photovoltaic Glass Furnaces

As China’s photovoltaic industry continues to expand, photovoltaic glass production capacity is steadily increasing. Consequently, photovoltaic glass furnace linings are subject to ever‑stricter requirements for high‑temperature erosion resistance and low impurity leaching, driving sustained growth in market demand for high‑performance specialty silica bricks. The photovoltaic‑furnace‑specific silica bricks manufactured by Zhengzhou Jinshan Refractories have already been successfully deployed in numerous projects undertaken by leading PV companies, delivering consistently reliable performance.

4 Policy Directions and Compliance Requirements for the Silica Brick Industry in 2026

In 2026, the refractory materials industry, to which silica bricks belong, saw the implementation of several new regulatory policies that have clarified industry development standards across multiple dimensions, including carbon emissions, energy efficiency ratings, and product quality.

4.1 New Regulations on Carbon Emission Management in the Refractory Materials Industry Have Taken Effect

The new regulations explicitly stipulate that silicon brick manufacturers must achieve a carbon emission intensity of less than 0.8 tonnes of CO₂ equivalent per tonne of product. Enterprises that fail to meet this requirement will be mandated to complete corrective measures within a specified timeframe, and those unable to comply will face production‑capacity restrictions. The core steps for compliant upgrades among silicon brick producers are as follows:

1. Conduct a carbon‑emission inventory across the entire production process and identify high‑energy‑consumption bottlenecks.
2. Complete the replacement of low‑energy‑consumption equipment to reduce energy consumption per unit of product.
3. Apply for product energy efficiency rating certification and publicly disclose the relevant parameters.
4. Establish a comprehensive, end-to-end quality control system that complies with the new regulatory testing requirements.

4.2 Implementation and Promotion of Product Energy Efficiency Labeling

Starting in the second half of 2026, China will officially implement an energy‑efficiency labeling system for refractory products. Mainstream refractories, including silica bricks, will be required to display their corresponding energy‑efficiency ratings, enabling downstream purchasers to readily assess product energy consumption and thereby driving the industry as a whole toward a lower‑carbon trajectory.
