How much high temperature can high alumina refractory bricks withstand?

High alumina refractory bricks are formed and calcined from bauxite or other raw materials with high alumina content. Aluminum silicate refractory bricks with Al2O3 content greater than 48% are also collectively referred to as high alumina refractory bricks, with high thermal stability and fire resistance. With a temperature above 1770℃, one of the important working properties of high-alumina refractory bricks is the structural strength at high temperatures. This characteristic is usually evaluated by the softening deformation temperature under load. The high-temperature creep properties are also measured to reflect the high-temperature structural strength. So how many degrees of high temperature can high alumina refractory bricks withstand? The test results show that the softening temperature under load increases with the increase of Al2O3 content.
