Alumina materials widely used in the field of materials engineering can be divided into two main groups: alumina and fused alumina. Both materials play an important role in many industrial and scientific applications, but there are important differences between them.

We will look at the two main types of corundum - white and brown - and the differences between them. These differences determine their different uses and performance in metalworking, ceramics manufacturing and other areas.

Black silicon carbide (commonly known as silicon carbide) is a ceramic composite material composed of silicon and carbon. It has a unique crystal structure in which the silicon and carbon in the lattice are arranged at equal intervals, resulting in a material with high hardness and high thermal conductivity.

Silicon carbide, also known as SiC, is a compound comprised of the elements ca rbon and silicon that has unique material properties and is employed in a wide range of applications. It has a high hardness, a h igh melting point, great thermal conductivity, and corrosion resistance, which allow it...
