Phlogopite mica remains stable at higher temperatures (to 900 °C (1,650 °F)) and is used in applications in which a combination of high-heat stability and electrical properties is required. Muscovite and phlogopite are used in sheet and ground forms.
In reference to mica, what are the thermal expansion coefficients? I want to know the coefficients at three directions: fast axis of mica, slow axis and the direction perpendicular to them. Thank you.
Our thermal products are able to withstand continuous temperatures of between 200°C and 900°C and peak temperatures of up to 1200°C under different environmental conditions and pressures. Von Roll supplies various state-of-the-art products from mica tapes for fire-resistant cables, mica paper sheets and tubes up to ready-to-use machined parts.
Mica gasket material is exceptional in it resistance to high heat. At temperatures over 900 F the ideal sealing material Grafoil® or flexible graphite cannot be used. Flexible graphite or Grafoill® will coke at those elevated temperatures when oxygen is present, where mica gasket material will not (900 - 1850 F). Mica gasket material is an excellent alternative in these high temperature (to

Mica has a low coefficient of expansion, high dielectric strength, good electrical resistivity, a uniform dielectric constant, and capacitance stability; at one time it was the best electrical and thermal insulator known. The iron content determines the color. Muscovite is generally gray, green, or brown; biotite, brown or black; lepidolite

Sheet muscovite and phlogopite have high thermal resistance and low electrical conductivity, and have traditionally found applications in heating and electrical appliances. Dry and wet-ground mica are produced in larger volumes for plasterboard, plasterboard joining cements, and fillers in paint and plastic. Annual consumption world wide is less than 300 000 t. Vermiculite is usually sold in

materials due to its extremely high temperature resistance and low coefficient of thermal expansion. The melting temperature of natural mica is around 1200–1300 C. The high melting temperature, however, does not say anything about the temperature resistance. Since natural mica is a hydro silicate,
01.02.2020· Recently, mica has been regarded as a suitable flexible substrate for high temperature applications because of their excellent transmittance and thermal stability. Mica exhibits good thermal stability at high temperatures even up to 1000 o C. The visible light transmittance can reach 90% for the ultrathin mica sheet.
