Different Types of Alumina
Aluminas are generally white but are sometimes pink (88% alumina) or brown (96% Alumina). The colour is derived from either the sintering additives or impurities in the raw materials. Dynamic-Ceramic produces a range of alumina from 96% - 99.9% purity.
Properties of Alumina
Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000°C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.
