Alumina Ceramic:

(Al2O3·H2O and Al2O3·3H2O) are the main minerals of aluminum in nature. After pulverizing, they are impregnated with high-temperature sodium hydroxide solution to obtain sodium metaaluminate solution; the residue is removed by filtration, the filtrate is cooled and aluminum hydroxide crystals are added. After a long time of stirring, the sodium aluminate solution will be separated into precipitates of aluminum hydroxide; the precipitate is separated and washed, and then calcined at a temperature of 950-1200 ° C to obtain α-type alumina powder, and the mother liquor can be recycled. This method was invented by the Austrian scientist K.J. Bayer in 1888 and is still the main method of industrial production of alumina. It is called the Bayer method.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
