About Fluorocrystalline Mica
Fluorocrystalline mica, also known as Fluorphlogopite Mica, synthetic mica, artificial mica, synthetic mica crystal, belongs
to the silicate type artificial mica crystal, is under the high
temperature condition of 1500°C, through strict process conditions
and material ratio, in platinum The mica crystals smelted in the
yttrium have a chemical formula of KMg3(AISi3O10)F2(OH)-, and do
not contain (OH)-. The (OH)-hydroxyl group is replaced by
F-(fluoro), which is similar to the fluorite mica. Materials
commonly used in the general industry are natural mica. Natural
mica is an underground ore naturally formed and belongs to the
class of silicates. Most of the industrial mica used is phlogopite
(brown) and muscovite. Its ideal chemical formula is
KAI2(AISi3O10)(OH)2. OH)-(Hydroxy), due to the presence of hydroxyl
(water molecules), its performance in all aspects is far lower than
that of fluorocrystalline mica.
The main characteristics of fluoride crystal mica:
1, high temperature: can work long-term in the 1100 °C environment.
The testing department of the Changchun Institute of Applied
Chemistry, Chinese Academy of Sciences (nationally recognized
testing institute) tested the thermal weight loss of 8% at 1100°C
for 48 hours, and the melting and devitrification temperature was
2. Electrical insulation: The volume resistivity is 10 times higher
than natural mica. Electrical breakdown strength is PTFE
Lean 10 times.
3, hot and cold blasting stability is very good
5 cycles of -40°C~70°C at the 5th Saibao Lab of the Ministry of
Inspection, all qualified.
Fluorophlogopite does not react with acid and alkali solutions, and
does not react with water. Under the long-term (2 to 3 years)
scouring of high-temperature and high-pressure water (including
acid and alkali), the original clarity and transparency can still
5, high frequency performance:
The dielectric constant of fluorite mica is 4.6 , and the
dielectric loss is (1~4)×10 4 tg , and the dielectric loss is very
low. And because of the pure texture, all parameters are extremely
6, optical properties
Since the fluorite mica contains less impurities, its light
transmittance is compared from infrared to ultraviolet.
High, the transmittance is close to 100%.
7, Mosaic (Mosaicity):
The Mosaicite of fluorocrystalline mica is less than 0.25 degrees,
which was produced in the experiment.
The neutron flame is not high enough to absorb multi-band light
beams and is an ideal neutron monochromator test material.
8, vacuum deflation performance:
The evaporative volume of fluorite mica is low, and it is measured
with a mass spectrometer and the trace gas released is only
O2, N2, Ar and other adsorbed gases. Since the H2O vapor is not
released, this is extremely valuable for use as an electrical
vacuum insulation material, which can greatly increase the service
life of the vacuum device.
9, excellent physical properties:
Fluorocrystalline mica has atomicity flatness, transparency,
separability and elasticity, not aging
It is not brittle and so on.
Due to the high temperature resistance, corrosion resistance, low
frequency loss, and high bulk resistivity
Absorb multi-band light beam, excellent light transmittance and
other advantages. Therefore it has become an ideal new material in
the high-end area.
Fluorocrystalline mica Available in:
In the range of 180mm×53mm or ∮76mm, it can be processed into
various shapes according to user requirements. Thickness within the
range of 0.02mm~1.0mm can be allocated according to user
requirements. The conventional thickness is 0.04~0.2mm.
