Ceramic Insulator Sealing Ring 99% 99.7% High Temperature Alumina
Ceramic Insulation Ring
Alumina ceramics are classified into high-purity type and ordinary
type.
The high-purity alumina ceramics have a Al2O3 content of 99.9% or
more. Since the sintering temperature is as high as 1650-1990 ° C
and the transmission wavelength is 1 to 6 μm, the molten glass is
generally used to replace the platinum crucible; Sexual and
alkali-resistant metal corrosion is used as a sodium lamp; it can
be used as an integrated circuit substrate and high-frequency
insulation material in the electronics industry.
our ceramic ring have a best high temperature resistance
performance.
we have multi type high temperature rings. hot sales in stocks,
also can be customized sizes and types.
