Hengjia low sodium tabular corundum, with Na,O content less than 0.1%, is suitable for high temperature materials, high-grade refractory materials, refractory products for ultra-pure metal smelting furnaces, ultra-pure casting sand, inert filler balls for pharmaceutical and chemical industries, etc.

 

Features
Hengjia tabular corundum has the following characteristics:
Low impurity content and high refractoriness;
High volume density and good volume stability after high temperature firing:
Low apparent porosity and low water absorption can improve the corrosion resistance of refractory materials in various atmospheres;
Good thermal shock stability can reduce thermal shock damage to refractory materials caused by changes in working temperature.
