What Is Precision Ceramic Parts And Its Application
Feb 08, 2019


Industrial ceramics, namely, ceramics for industrial production and industrial products.It is a kind of fine ceramics, which can perform mechanical, thermal and chemical functions in application. Because the industrial ceramics with advantage of high temperature resistance, corrosion resistance, wear resistance, resistance to erosion, it can replace metal materials and organic polymer materials used in harsh working environment, has become a important materials for traditional industrial transformation, new industries and high-tech indispensable, in energy, aviation, machinery, automobile, electronics, chemical industry and other fields has a very wide application prospects.Using corrosion resistance, and with good chemical stability of ceramics to produce metal smelting crucible, heat exchanger, biological materials such as artificial enamel joints, using the unique capture and absorption of neutrons in the ceramic to produce a variety of nuclear reactor structure materials.


1. Aluminum ceramic:

AL2O3 is the main component of the ceramic (AL2O3 quality score sharing >45%).According to the main crystal phase of the ceramic body, it can be divided into corundum porcelain, corundum mullite porcelain and mullite porcelain. AL2O3 can also be divided into 75 porcelain, 95 porcelain and 99 porcelain, etc.


Application:

Alumina porcelain has high melting point, high hardness, high strength, good resistance to chemical corrosion and dielectric properties. However, it has high brittleness, poor impact resistance and thermal shock resistance, and cannot withstand drastic changes of ambient temperature.It can be used to make high temperature furnace tube, furnace lining, spark plug of internal combustion engine, etc


2. Silicon carbide ceramics

The biggest characteristic of silicon carbide ceramic is high temperature strength, high heat conduction ability, high wear resistance, corrosion resistance, creep resistance, is often used for national defense, aerospace and other high temperature sintering in the field of materials science and technology, is used in the manufacture of rockets the exhaust nozzle, nozzle for casting metal, such as high temperature furnace tube parts.


Application:

Due to the high heat conduction capacity, it can also be used to manufacture high-temperature strength parts such as vane and bearings of gas turbines, as well as materials used as high-temperature heat exchangers and encapsulation materials of nuclear fuels.
