What factors affect the high temperature resistance of alumina ceramics
As an important material in the field of industrial wear protection, wear resistant ceramics have always attracted much attention for their excellent high temperature resistance. So, what are the key factors that affect the high temperature resistance of wear-resistant ceramics? The following are several aspects that we have analyzed in depth: 1. The criticality of material purity: The wear-resistant ceramics we usually refer to generally refer to alumina wear-resistant ceramics, and their high temperature resistance is closely related to the purity of alumina. Alumina wear-resistant ceramics are born in a sintering environment of up to 1700°C, and they themselves have excellent high temperature resistance. However, when the purity of alumina is insufficient, other elements will be doped into the ceramics, which will cause adverse effects due to differences in their thermal expansion and contraction properties under high temperature or rapid temperature changes. Therefore, when facing
