Sintered Zirconia Corundum Brick

lianxin-bai — Wed, 14 Apr 2021 11:25:10 +0000

Product Description

Description of Sintered Zirconium Corundum Fire Brick

Sintered zirconia-corundum refractory bricks are high-performance refractory materials made primarily from alumina (Al₂O₃) and zirconium oxide (ZrO₂) through a high-temperature sintering process. Although they share similar compositions with the fused cast zirconia-corundum bricks (electrominated bricks), they differ fundamentally in their production processes, microstructure, and applications.

Production Process: Finely ground raw materials are mixed, high-pressure molded, and fired at high temperature (approximately 1700-1750℃).

Microstructure: Relatively uniform structure, containing a small number of pores and internal microcracks.

Core Advantages: Excellent thermal shock resistance (resistance to rapid heating and cooling); not easily cracked due to drastic temperature changes.

Main Applications: Upper space of glass furnaces (not in direct contact with molten glass), regenerator partition walls, slide rails of metallurgical heating furnaces, etc.

Production Process: Raw materials are completely melted in an electric arc furnace, then poured into molds and cooled to form the final shape.

Microstructure: The structure is extremely dense, but shrinkage cavities are unavoidable (caused by volume shrinkage during casting).

Core Advantages: Dense structure, extremely strong resistance to molten glass erosion.

Main Applications: Critical parts of glass furnaces that directly contact high-temperature molten glass, such as the pool walls, flow channels, and furnace sills.

Characteristics of Sintered Zirconium Corundum Brick

Sintered zirconium corundum fire bricks have these characteristics:

Strong erosion resistance
High density and low porosity
Excellent thermal shock resistance
High structural strength at high temperatures

characteristics	calcium-free silica bricks	traditional silica bricks	advantages
chemical composition	SiO₂ ≥ 99%, CaO ≤ 0.05%	SiO₂ approx. 95-97%, CaO approx. 2.5%	Extremely high SiO₂ purity, completely eliminating the CaO binding phase.
Alkali Erosion Resistance	Significantly Improved	Average	Due to the lack of CaO reacting with alkali vapors, erosion resistance is greatly enhanced, which is its core advantage.
Load Softening Temperature	≥ 1690℃	Lower	Can work stably at higher temperatures for extended periods without softening or deformation.
Thermal Expansion Rate	≤ 0.65% at 1000℃, lower than ordinary silica bricks	Higher	Good high-temperature volume stability; does not expand, crack, or shrink after long-term use.
Thermal Shock Resistance	Excellent (1100℃ water cooling > 30 times)	Average	Better resists thermal shock damage caused by rapid temperature changes.
