4. Excellent Insulation

Product Description

High-Purity Wearable Alumina Ceramic Tube

STA alumina crucible tube is the most mature of the engineering ceramics, offering excellentel ectrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.

Alumina are generally white but are sometimes pink (88% alumina)or brown (96% Alumina). The colour is derived from either the sintering additives or impurities in the raw materials. Dynamic-Ceramic produces a range of alumina from 96% - 99.9% purity.

Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1800°C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced.
