Minerals containing Alumina represent some 15% of the earth's crust. It is therefore an abundant material and virtually inexhaustible, unlike raw materials for many alloys developed for special applications. The combination of high thermal conductivity, low thermal expansion and high compressive strength leads to good thermal shock resistance, so alumina is suited to furnace use such as crucibles,...
