Overview of TiC Powder

Titanium Carbide (TiC) powder is a type of ceramic powder with exceptional hardness and resistance to wear and corrosion. As one of the hardest known materials, TiC is often used in high-performance applications such as cutting tools, abrasives, coatings, and as an additive in metal matrix composites. Its properties make it ideal for environments exposed to extreme conditions, such as high temperatures, high wear, and corrosive environments.

TiC powder is often synthesized through various chemical processes, typically using titanium tetrachloride (TiCl4) and carbon sources at high temperatures. The resulting TiC powder can be customized for different industrial applications based on factors like particle size, purity, and composition.

Key Characteristics of TiC Powder

  1. 硬度: TiC is known for its extreme hardness, surpassing that of many other materials. It ranks 9 on the Mohs scale of hardness, which makes it suitable for cutting tools, abrasives, and coatings.
  2. 熱安定性: TiC powder can withstand high temperatures, maintaining its structural integrity even in extreme heat, making it an ideal material for high-temperature applications like jet engines.
  3. 耐摩耗性: Due to its hardness, TiC powder is highly resistant to abrasion and wear. This makes it an excellent choice for use in heavy-duty machinery, mining, and automotive components.
  4. 耐食性: TiC exhibits excellent resistance to corrosion, particularly in high-temperature and chemically aggressive environments, ensuring the longevity of parts and components.
  5. 電気伝導率: TiC is also a good conductor of electricity, which makes it valuable in electrical contacts, resistors, and other electronic applications.

構成 TiCパウダー

Titanium carbide powder is primarily composed of two elements: titanium (Ti) and carbon (C). The powder can vary in its precise composition based on the method of production, but the ratio of Ti to C remains relatively constant at 1:1. Here’s a breakdown of what makes up TiC powder:

エレメントSymbolPercentage by WeightRole in Composition
チタンTi~50%Provides hardness and thermal stability
カーボンC~50%Contributes to high hardness and wear resistance

In addition to these two primary elements, TiC powder may also contain trace amounts of other elements such as oxygen, nitrogen, or metallic impurities depending on the synthesis process.
