China has a large ceramics and refractory materials industry because these products are needed in steelmaking, construction, glass, electronics, cement, chemicals, and other high-temperature manufacturing processes. The industry ranges from traditional ceramic products to advanced technical ceramics and specialized refractory materials.
Why Refractories Are Important
Refractory materials can withstand very high temperatures and harsh chemical conditions. They are used to protect industrial equipment such as:
- Steel furnaces
- Ladles and converters
- Glass furnaces
- Cement kilns
- Non-ferrous metal furnaces
- Chemical processing equipment
Without suitable refractory materials, equipment would suffer faster from heat, corrosion, and mechanical wear.
China Refractory Industry
China is one of the world's largest producers and consumers of refractory materials. Major producers supply products such as:
- Refractory bricks
- Monolithic refractories
- Castables
- Ceramic fibers
- Insulating materials
- Magnesia-based products
- Alumina-based products
- Silicon-carbide materials
Steelmaking is one of the biggest users because production involves extremely high temperatures.

Its products include:
- Magnesia bricks
- Magnesia-carbon bricks
- Refractory materials
- Monolithic products
- Other basic refractories
These materials are particularly important for steelmaking because they can withstand high temperatures and aggressive slag conditions.
Beijing Lier High-Temperature Materials
Beijing Lier High-Temperature Materials focuses on refractory materials used in demanding industrial processes.
Its products include:
- Refractory bricks
- Monolithic refractories
- Refractory materials for steelmaking

China Northern Rare Earth and Advanced Ceramic Materials
China also has companies involved in advanced ceramic materials, particularly ceramics based on materials such as alumina, zirconia, silicon carbide, and other engineered compounds.
These materials are different from traditional bricks because they are designed for specific technical properties such as:
- Electrical insulation
- Wear resistance
- High-temperature stability
- Corrosion resistance
- Mechanical strength
They are used in electronics, machinery, energy systems, sensors, and industrial equipment.
Ceramic Fiber Producers
China has a significant ceramic-fiber manufacturing sector. Ceramic fibers are lightweight insulating materials that can operate at very high temperatures.
They are used for:
- Furnace insulation
- Kiln linings
- Industrial heating equipment
- Petrochemical equipment
- Thermal insulation
- High-temperature processing
Ceramic fiber products are different from dense refractory bricks because their main purpose is often thermal insulation and reducing heat loss.
How the Products Differ
Advanced ceramics:
Engineered for specialized properties such as electrical insulation, hardness, wear resistance, and thermal stability. They are widely used in electronics, machinery, energy, and precision manufacturing.
Ceramic fibers:
Lightweight and designed mainly for thermal insulation. They are useful in furnaces, kilns, heaters, and other high-temperature equipment.
Refractory bricks:
Dense materials used to protect furnaces and industrial vessels from extreme heat, chemical attack, and mechanical wear.
Monolithic refractories:
Materials such as castables, ramming mixes, and repair materials that are installed directly onto industrial equipment instead of being supplied as traditional bricks.
Importance to Different Industries
Steel: Refractories protect furnaces, converters, ladles, and other equipment from molten steel and slag.
Construction: Traditional ceramics are used for bricks, tiles, sanitaryware, and other building products.
Glass: High-temperature refractories are required inside glass-melting furnaces.
Electronics: Advanced ceramics provide electrical insulation, heat resistance, and precise mechanical properties.
Manufacturing: Ceramic and refractory materials help industrial equipment operate under extreme heat, pressure, wear, and chemical conditions.
Conclusion
China's ceramics and refractory industry covers a wide range of materials, from traditional ceramic products and refractory bricks to advanced ceramics and ceramic fibers. Companies and research organizations such as Sinosteel Luoyang Institute of Refractories Research, Yingkou Qinghua Group, and Beijing Lier operate in different parts of this market. Refractory bricks are mainly used for high-temperature protection, ceramic fibers for thermal insulation, and advanced ceramics for specialized electrical, mechanical, and high-temperature applications across China's major industrial sectors.
