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 carbide ceramic (SiC)

Silicon carbide ceramics are considered one of the best precision ceramic materials for extremely high temperature applications

Hexagonal boron nitride ceramic (HBN)

Hexagonal boron nitride ceramics have a wide range of uses and have excellent mechanical properties, high temperature resistance, thermal shock resistance, ablation resistance, and molten metal corrosion resistance, making them widely used in aerospace, electronics, metallurgy, machinery, nuclear energy, etc. fields with potentially important application value.

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.

    How to grind sapphire workpieces

    Sapphire consists of Al2O3 and has a Mohs hardness of 9, which is second only to superhard materials in hardness. Due to its superior light transmittance and wear resistance, it is mostly used in the substrate of LED light-emitting components, optical windows, and watch cases of high-end watches and cell phone cameras, etc.The processing process usually requires high precision, fast processing efficiency, low material loss and a clean working environment. Diamond is the hardest and most wear-resistant material in nature, so diamond tools are the best choice for processing sapphire materials.
