High Quality Lightweight Insulating Corundum Mullite Brick is a shape made from refractory ceramics. It is used in lining furnace kilns, fireboxes and fireplaces. Its primary purpose is to withstand high temperature and also to retain the heat for greater energy efficiency. We offer wide range of low, medium & high alumina refractory firebricks. Apart from standard shapes, we can also make special shapes as per custom requirements. Our bricks are made by dry pressing method and are fired in electronically controlled tunnel kiln. We regularly supply bulk quantities of firebricks to wholesalers, cement factories, steel factories, chemical industries, etc. across many countries. We constantly keep close checks on quality and costs, so that our clients can get good quality bricks at most reasonable prices.

 

High Quality Lightweight Insulating Corundum Mullite Brick are made from high-purity refractory clays ;temperature of use ranging from 1100 to 1700 and each grade is formulated to meet specific thermal and physical requirements . For higher temperature products , their addition of alumina are graduated .Each grade is added by classified organic filler . This organic filler burns out during manufacture process to give a uniform and controlled pore structure .
