Si3n4 Bonded Sic Protection Tube

After ten years of development, the company has formed a relatively rapid development foundation and a complete development system, and formed a strategic pattern with sic thermocouple protection tube, ceramic bearings si3n4 skate, coors perforated ceramic alumina sheet development as the main line, multi-directional extension of the industrial chain, and gradually marching into industries closely related to the industry and actively encouraged by the state. The corporate purpose reflects the company's social values and the basic attitude toward shareholders, employees and social obligations. We combine our CSR development vision and sustainable development plan to contribute to future sustainable development through our business. We strive to grasp the industrial opportunities, optimize the business layout, in order to achieve leapfrog development.

Description

Alumina ceramic tube is a special corundum ceramic tube made of Al₂O₃ as the main raw material, rare metal oxide as the flux, and calcined at a high temperature of 1,700. It is widely used in various industrial furnace fields, as furnace tube (wire tube, wire winding tube, oxygen blowing tube, etc.), support, threading, insulation and other purposes.

Property

Ceramic tube is mainly based on grouting molding, and there are other molding methods such as extrusion and hot die casting.

Classification

Alumina ceramics are divided into two types: high-purity type and ordinary type.

High-purity alumina ceramics are ceramic materials with an Al2O3 content of more than 99.9%. Because their sintering temperature is as high as 1650-1990 ℃, and the transmission wavelength is 1 to 6 μm, they are generally made into molten glass to replace platinum crucibles; use its light transmission It can be used as a sodium lamp tube, and it can be used as an integrated circuit substrate and high-frequency insulating material in the electronics industry.

Ordinary alumina ceramics are classified into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to different Al2O3 content. Sometimes those with 80% or 75% Al2O3 content are also classified as ordinary alumina ceramic series. Among them, 99 alumina porcelain is used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve discs; 95 alumina porcelain is mainly used as corrosion-resistant and wear-resistant parts; 85 porcelain Because it is often mixed with some talc to improve the electrical performance and mechanical strength, it can be sealed with metals such as molybdenum, niobium, and tantalum, and some are used as electrical vacuum devices.
