Product Description of High Alumina Refractory Cement CA50 CA60 CA70 CA80
High Alumina Refractory Cement/Calcium Aluminate Cement/Aluminate Cement are collectively referred to as refractory cement. High alumina cement (formerly known as bauxite cement) is a hydraulic cementing material made of high-purity calcium materials and high-purity alumina as the main raw materials, and clinker with alumina content of about 50%.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.
CA-50, CA-70, CA-80, the alumina content is greater than 48%, 68% and 77% respectively. Its refractoriness is greater than 1650°C. The use temperature can reach 1800℃, and the impurity content is lower than other common cements.
