High Alumina Bricks and Fire Bricks

Alumina is one of the most matured engineering ceramics, which provides excellent electrical insulation properties in combination with supreme hardness and good wear resistance but has a relatively low strength and fracture toughness. It is manufactured being an electrically insulating material; it possesses high electrical resistivity which further increases by virtue of purity.

We can describe a firebrick, or refractory brick as a block of refractory ceramic material which is utilized in lining furnaces, kilns, fireboxes, and fireplaces. Our company’s silica firebricks which line steel-making furnaces can remain unaffected at temperatures up to 1650°C (3000°F), which would melt many other types of ceramic, and a part of the silica firebrick also liquefies. HRS is another material which have same composition, is used to make the insulating tiles of the space shuttle.
