Functional ceramics can improve the density, finishes, cold-hot fatigue
property, fracture toughness and creep resistance property of ceramics.
α-alumina is also an excellent far-infrared emission material, which
can be used in chemical fiber products and high-pressure sodium lamps
as far-infrared emission and insulation materials.
α-alumina has the nice insulation property due to high electrical
resistivity and can be used as main fittings and integrated circuit
substrate for YGA laser crystal.
