High Temperature High Purity 99% Alumina Ceramic Tube
Description:
Alumina (Aluminum oxide) offers excellent electrical insulation,
high-temperature resistance together with high hardness and good
wear resistance, so alumina ceramic parts are commonly used as a
kind of insulating, heat resistance and anti-chemical engineering
and structural ceramic components, including ceramic electrical
insulator, high voltage ceramic holder, ceramic parts in a
high-temperature furnace, ceramic seal disc in pump and so on.
Our factory produces a selection of purity of alumina from 40% to
99.8%, all of the ceramic parts we supplied are with a dense body
via dry pressing, hot pressing, ceramic injection molding, and ISO
pressing. In order to achieve some special application for fitting,
reducing the friction, increasing the insulation, we provide a
serial of secondary processes after sintering, covering CNC
machining, polishing, glazing, and metalizing.
