Calcined Alpha alumina powder

ZSR company offers a wide range of calcined alumina used in refractory industry. These products are classified according to their calcination degree, soda content and grinding mechanism. Considering calcination degree, they are classified as Hard Calcined and Medium Calcined. Higher calcination degree of alumina leads to more crystal growth and higher alpha phase content. The soda content of calcined alumina is precisely controlled in order to achieve higher refractoriness and improved high temperature mechanical properties. The soda content is classified as Normal Soda, Medium Soda, Low Soda and Ultra Low Soda. Depending on final usage, calcined alumina is used unground or ground. Grinding may be done in batch milling process or continuous milling processes including ball mill and jet mill. During milling, particles are disintegrated into single crystals and agglomerates containing several crystals.ZSR company offers a wide range of calcined alumina used in refractory industry. Thes
