High temperature resistant ceramic parts are widely used in various fields of our country’s national economy and people’s livelihood. So what are the high temperature resistant ceramic parts and what are they used for? Pintejin zirconia ceramic machining manufacturers answer for you.
High temperature resistant ceramics is a general term for ceramic materials whose melting temperature is above the melting point of silicon oxide (1728°C). High temperature ceramic cutter is an important part of special ceramics, and sometimes also used as a component of high temperature refractory materials.
According to the main chemical composition of the material, it can be divided into high temperature oxide ceramics, such as zirconia ceramics and alumina ceramics, carbide ceramics, boride ceramics, nitride ceramics and silicide ceramics. Usually has high temperature resistance, high strength, high hardness, good electrical properties, thermal properties and chemical stability.
Oxide high-temperature ceramics are mostly sintered in an oxidizing atmosphere, vacuum, etc., and non-oxide high-temperature ceramics are often sintered by hot pressing or in a specific atmosphere (such as argon, nitrogen).
There are also methods such as hot isostatic pressing and microwave sintering. Zirconia high temperature ceramic parts For thin films, etc., it can also be prepared by vapor deposition and other methods. It can be used as a high-temperature structural material in many departments such as aerospace, atomic energy, electronic technology, machinery, chemical industry, metallurgy, etc. It is an indispensable high-temperature engineering material for modern science and technology. Specific uses
- 1. Release agent for metal forming and lubricant for metal wire drawing.
- 2. Special electrolytic and resistance materials in high temperature state.
- 3. High-temperature solid lubricants, extrusion anti-wear additives, additives for the production of ceramic composite materials, refractory materials and anti-oxidation additives, especially in the case of anti-corrosion of molten metals, heat-enhancing additives, and high-temperature-resistant insulating materials.
- 4. Heat-sealing desiccant for transistors and additives for polymers such as plastic resins.
- 5. It can be pressed into various shapes of boron nitride products, which can be used as high temperature, high pressure, insulation and heat dissipation parts. 6. Heat shielding materials in aerospace.
