Performance and purity breakdown of high temperature wear-resistant ceramic tubes

Release time：2024-09-11click：1

Alumina high-temperature wear-resistant ceramic tube is a ceramic material based on alumina (Al2O3). Alumina ceramic has good conductivity, mechanical strength and high temperature resistance Insulating properties. Alumina high-temperature wear-resistant ceramic tubes have a wide range of uses. Due to the superior properties of alumina materials, their applications in modern society have been increasingly recognized and used to meet the needs of daily and industrial special properties. .

Alumina high-temperature wear-resistant ceramic tubes can be roughly divided into: high-purity type (alumina with high purity content, such as more than 99%) and ordinary type (purity content 95% %-99%) and low purity (purity content below 95%). Among them, 99 alumina ceramic materials are used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valves, etc.; 95 alumina ceramics are mainly used for corrosion-resistant and wear-resistant parts; for example 85 porcelain is often mixed with some talc, which improves the electrical properties and mechanical strength. It can be sealed with molybdenum, niobium, tantalum and other metals, and some are used as electric vacuum devices.
