Casting mica material

Casting mica material is a kind of microcrystalline ceramic material prepared by melting and casting fluorophlogopite crystallites. It has the cleavability of mica, which makes itself easily machined by cutting, drilling, turning and milling. Meanwhile, it behaves the same good properties as fluorophlogopite in terms of electrical insulation, high temperature and thermal shock resistance. Moreover, microcrystalline synthetic mica ceramic has excellent chemical stability and can be used in the atmosphere of hydrogen, ammonia and chlorine without corrosion for a long time.

Vacuum leak rate 1.0 x 10-9 E.1/sec Thermal conductivity 1.2 W/m·K
Volume resistivity 3×1013Ω.cm Long-term usage temperature 900℃
Surface resistivity 2.85 x 1013Ω Maximum usage temperature 1100℃
Dielectric strength 10KV/mm Flexural strength ≥45 MPa
Dielectric constant 6.0 Compressive strength ≥110 MPa
Dielectric loss tgδ 4.35 x 10-3 Hardness 25


Fields of application:
    Widely used in kiln furniture of metallurgy and melt chloridate, metallurgy crucible, inner lining of electron-bean welder and medium- frequency induction furnace, catelectrode insulation of ionitriding furnace, copycat fever framework, insulators, framework of many electronic products and corrosion resisting parts.

Specifications:
    Cylinder rods: φ10~500mm
    Other dimensions are available upon request.
