Sintered Chrome Corundum

Chrome corundum series, made of Al2O3 mixing with CrO2 or ZrO2 in a certain proportion, is commonly produced with an adoption of special refractory production process.

According to the ingredients, it is usually divided into:
Chrome corundum products;
Chrome-zirconium corundum products;
Sometimes, it is made into composite products with corundum or clayey materials;
