Classification and application of precision ceramics

Precision ceramics are high-precision ceramics manufactured using "strictly selected or synthesized raw material powders" through "strictly controlled manufacturing processes" and "precisely adjusted chemical compositions".

Precision ceramic materials can make products lighter, more efficient, more durable, reduce maintenance intervals and lower operating costs. Due to their significant high-temperature capabilities, hardness, and electrical properties, they are often used to replace metals, polymers, and refractory materials in a variety of applications.

Common precision ceramic materials

Alumina ceramic (Al 2 O 3 )

Alumina ceramic is one of the most commonly used precision ceramic materials. Alumina ceramics are used in many applications such as containing molten metal where the material operates at very high temperatures under heavy loads, as an insulator in spark plugs, and in some unique applications such as dental and medical uses. Chromium-doped aluminum oxide is used to make lasers.

Silicon nitride ceramic (Si 3 N 4 )

Silicon nitride (Si 3 N 4 ) has the most versatile combination of mechanical, thermal and electrical properties of all precision ceramic materials. It is a high-performance precision ceramic that is very hard and has excellent resistance to thermal shock and impact. It exceeds the high temperature capabilities of most metals and has excellent creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material capable of withstanding the harshest conditions in the most demanding industrial applications. Silicon nitride ceramics are an excellent choice when high temperatures and high load capabilities are required.
