White Tabular Alumina Powder for Refractory

White Tabular Alumina Powder for Refractory

Tabular alumina is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on, with low shrinkage.

Description

Our company has a sound process, we produce good quality, high-grade y zeolite catalyst, pseudoboehmite alumina, boehmite alumina powder in order to meet the market demand. Our company adheres to the 'pursuit of excellence, never stop' spirit of enterprise, strategic. We are sincere and trustworthy, and set a corporate model. With our unique core technology, the advantage of whole industry chain integration, and continuous innovation and creativity, we take up the responsibility of moving the industry to a higher level. We make use of cross-border integration and flexible deployment of assets, technologies, talents and markets to achieve scientific distribution of resources and optimal operational efficiency.

Tabular alumina is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on, with low shrinkage. It has a sheet crystal structure, small pores and more closed pores. It has high purity, good volume stability, and minimal reburning shrinkage. The resistant materials or castables used for production have good thermal shock stability and flexural strength after high temperature treatment.There are 5-10 /3 -6 /1 -3 /0 -1 /0 -0.045mm and other brands.
