99.97% Alumina ceramic is the representative material of today’s technical ceramics. Similar to sapphire, 99.97% Alumina ceramic is comprised of corundum crystals. My 99.97% Alumina is manufactured with our SFG (Small, Fine Grain) technology and thus it has outstanding properties as an industrial material. With a hardness next to diamond, boron carbide and silicon carbide, my 99.97% Alumina ceramic with SFG technology has superior wear resistance. 99.97% Alumina ceramic has excellent high insulation resistance at elevated temperatures, high dielectric strength at high voltage, and low dielectric loss tangent at high frequencies. My 99.97% Alumina ceramic is inert to oxidation, is not corroded by chemical agents, and is not subject to radiation damage.
