Steatite Ceramics is widely used for insulation in the electrical and electronic industries.It is a lower cost
material than alumina,but has excellent resistance
characteristics(which can be maintained at high temperatures)and
moderate mechanical strength.
The low firing shrinkage of this ceramic allows us to produce parts
with precise tolerances.The use of cost-effective production
techniques can achieve small sizes and high-precision shapes,which
make steatite ceramic ideal for mass paroduction of insulating components.
Because of its excellent dielectric properties,tal has been used in
large electrical systems and electronic/household equipment for
many years.It has high volume resistivity and high dielectric
strength,so it is very suitable for the production of electrical insulation components.
Steatite Ceramic is a low-cost material with high resistance at high
temperature,good mechanical strength and extremely low dielectric
loss factor.These characteristics make it very suitable for high
frequency,low loss and high voltage insulation.In addition,talc is
an excellent material for electrical engineering because it can be
easily molded and sintered into various forms,such as
gaskets,bushings,resistance forms,voids and beads.
Talc has been used for many years in large industrial
systems,household appliances,aerospace and automotive
applications,and specialized electronic technology inutruments.
