Plate-shaped corundum is a pure, additive-free sintered corundum. It has a coarse-grained, well-developed α-Al2O3 crystal structure. The plate-shaped corundum SEM shows a plate-like crystal structure with small pores and more closed pores, and the porosity is roughly the same as that of fused alumina, with high purity, good volume stability, and minimal reburning shrinkage. Materials or castables have good thermal shock stability and flexural strength after high temperature treatment.
Plate-shaped corundum can be used as the main component in aluminum-carbon, aluminum-magnesium-carbon, magnesium-aluminum-carbon, magnesium spinel, aluminum-chromium refractory bricks, and it can also be introduced into high-aluminum alloys as a rich alumina component Shaped refractories can be widely used in steel, casting, ceramics and other industries. Among them, the application in the steel industry covers the entire process of ironmaking and steelmaking.
