Zirconium bricks are an indispensable key refractory material in the glass industry. Their core purpose is to construct an “inner liner” for the glass melting furnace, resisting high temperatures and chemical corrosion, directly affecting the furnace’s lifespan and the quality…
Zirconium bricks, especially fused zirconia-corundum bricks (AZS bricks) and high-zirconia bricks, play a crucial role in high-temperature industrial kilns due to their excellent erosion resistance, high-temperature stability, and low pollution. Their application is primarily in the glass industry, but extends…
Zircon bricks do not refer to a specific type of brick, but rather to a general term for refractory materials whose main components are zircon (ZrSiO₄) or zirconium oxide (ZrO₂). Due to their high melting point, excellent thermal shock resistance,…
Zircon bricks are refractory products made primarily from zirconium oxide (ZrO₂) or zircon (ZrSiO₄). Due to their high melting point, excellent erosion resistance, and thermal shock resistance, they are widely used in high-temperature industries such as glassmaking and metallurgy. Their…
Corundum bricks are high-performance refractory materials with α-Al₂O₃ (corundum) as the main crystalline phase and an alumina content typically greater than 90%. Due to their excellent physicochemical properties, they are widely used in key components of high-temperature industries such as…
When using corundum bricks in kilns, the core concerns are their thermal shock stability, construction details, and compatibility with the operating environment. I. Strictly Control Thermal Shock and Temperature Fluctuations Corundum bricks have poor thermal shock stability and limited resistance…
Corundum bricks, primarily composed of high-purity α-alumina, possess a refractoriness exceeding 1800℃, extremely low impurity content, strong chemical inertness, and excellent high-temperature insulation properties. They are a core refractory lining material for various high-temperature sintering kilns in the electronics industry,…
Corundum bricks play a crucial role in the ceramic industry, primarily serving as linings and key structural components for high-temperature kilns. This is due to their high alumina (Al₂O₃) content (typically ≥90%), which endows them with high refractoriness, high-temperature structural…
Corundum bricks have an alumina content ≥90%, a refractoriness exceeding 1790℃, a dense structure, high high-temperature strength, and are resistant to corrosion from reducing gases such as hydrogen and carbon monoxide. They are also resistant to erosion and penetration by…
Corundum bricks (Al₂O₃ content ≥90%) play an irreplaceable role in the metallurgical industry due to their superior high-temperature performance and chemical stability, and are an indispensable key material in modern steel and non-ferrous metal smelting. In the steel industry, corundum…
