Alumina ceramics are sintered under the temperature of 1450~1800℃, which contain aluminum oxide as the main raw material and 6~30% of sintering additives, such as clay, MgO, CaO, TiO. The purer alumina ceramics are, the better performance can be obtained, however the manufacturing of alumina ceramics also becomes more difficult with aluminum oxide proportion increases. Pure alumina ceramic can be ...

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,...
