Product Description

Alumina Advanced Engineering Ceramic Components /  Fine Mechanical Ceramic Parts

 

1. Description:

Advanced engineering ceramic components / mechanical ceramic parts widely apply for many different fields.While many ceramics are electrical insulators this is not true of them all. Some ceramics are semiconductors at room temperature and reasonably good conductors at elevated temperatures, where this stimulus provides sufficient motivation for electron motion. Given this, and the mechanical and chemical stability of ceramics at high temperatures, advanced ceramics are exceptional materials for high temperature heating elements. Many metal heating elements reach maximum operating temperatures around  approx 1100-1200^circ text{ C}in air. Ceramic materials such as

text{MoSi}_2are used up until  approx 1800^circ text{ C}in air. Many super conducting materials – the complete opposite end of the spectrum to insulators - are also ceramics.
