Structural Ceramics With Superior Strength

Hangzhou JWG Technology Co.Ltd | Updated: May 18, 2017

Structural ceramics are advanced ceramics with high temperature resistance, scour resistance, corrosion resistance, high hardness, high strength, low creep rate, and so on.

Structural ceramics with superior strength, hardness, insulation, heat conduction, high temperature, oxidation resistance, corrosion resistance, abrasion resistance, high-temperature strength and other characteristics, so in very harsh environment or engineering application conditions, demonstrated high stability and excellent mechanical properties, in the material industry has been much attention, its use is also growing. and the global and domestic industry for high-precision, high wear-resistant, high-reliability mechanical 0 components or electronic components of the increasingly stringent requirements, so the demand for ceramic products is very important, its market growth rate is also quite impressive.

Structural Ceramics

In the material, there is a kind of material called structural material mainly to make use of its strength, hardness and toughness, such as mechanical properties of various materials. Metals are widely used as structural materials. However, because metals are susceptible to corrosion, oxidation resistance at high temperatures is not suitable for use at elevated temperatures. The emergence of high-temperature structural materials make up the weakness of metallic materials. Such materials can withstand high temperatures, not afraid of oxidation, Structural Ceramicsacid and alkali corrosion, hardness, wear resistance, small density and so on, as high-temperature structural materials, very suitable.

1. Alumina Ceramics

Alumina Ceramics (synthetic corundum) is a promising high-temperature structural material. It is very high melting point, can be advanced refractory, such as crucible, high temperature furnace tubes. With the advantages of alumina hardness, the corundum ball machine used in the lab can be manufactured to grind the material less hardness than it. With high-purity raw materials, the use of advanced technology, also can make alumina ceramics become transparent, can make high-pressure sodium lamp tubes.

2, silicon nitride ceramics

Silicon nitride ceramic Ceramics is also an important structural material, it is a kind of superhard material, small density, its own lubrication, and wear resistance, in addition to hydrofluoric acid, it does not react with other inorganic acids, strong corrosion resistance, high temperature can resist oxidation. And it can resist hot and cold shocks, heating up to 1000 percent in the air, the rapid cooling and then heated, will not shatter. Silicon nitride is such a good characteristic that people often use it to make bearings, turbine blades, Structural Ceramicsmechanical seals, permanent molds and other mechanical components.

3, boron nitride ceramics, boron carbide ceramics

4. Man-made Gems

The main ingredients of ruby and Sapphire are Al2O3 (corundum). Ruby is red because there is a small amount of chromium-containing compounds, whereas blue sapphire is due to mixing a small amount of titanium compounds. In the 1900, the scientists used the alumina melt to add a small amount of chromium oxide, making the quality of 2g-4g Ruby. Now, Ruby and Sapphire, big to 10g.
