97 alumina
Your current location is: Website home page " Ceramic material " alumina " 97 alumina

97 alumina (Aluminium oxide) is a white solid, a compound of aluminum and oxygen, and its molecular formula is Al2O3. It is also known as bauxite in mining, ceramics and materials science. The purity is 97%. Water soluble white solid, odorless, tasteless, highly rigid, easy to absorb moisture without deliquescence (burn without moisture). Amphoteric oxides, soluble in inorganic acids and alkaline solutions, are almost insoluble in water and non-polar organic solvents; relative density (d204) 4; melting point 2050 C.

97 alumina Application area 1) high strength and high temperature stability: decorative porcelain, nozzle, rocket and missile shield.
2) high hardness and high wear resistance: cutting tools, molds, abrasives, bearings, artificial gemstones.
3) low dielectric loss, high resistivity and high insulation: spark plug, circuit board, tube holder;
4) high melting point and corrosion resistance: refractory, crucible, furnace tube, thermocouple protective sleeve, etc.
5) ionic conductivity: solar cell materials and battery materials.
6) biocompatibility: it can also be used to make artificial bones and artificial joints.
