Overview
Titanium Nitride (TiN) powder is a ceramic material renowned for its high hardness, thermal stability, and distinctive golden-yellow color. It is synthesized through processes like reactive sputtering or chemical vapor deposition (CVD). TiN powder is widely used in industrial applications due to its exceptional wear resistance and ability to enhance the durability of tools and components. In addition to its mechanical properties, TiN powder is valued for its electrical conductivity and biocompatibility, making it suitable for specialized applications in electronics and medical devices. Its versatility and performance benefits have cemented its role in advanced manufacturing and engineering sectors.
Physical and Chemical Properties
TiN powder exhibits a cubic crystal structure, contributing to its high hardness (approximately 2000 HV) and excellent wear resistance. Its melting point of 2930 °C makes it suitable for high-temperature environments. The material is chemically inert, resisting oxidation and corrosion in most conditions. TiN powder is insoluble in water but dissolves in aqua regia, a mixture of nitric and hydrochloric acids. Its density of 5.43 g/cm³ and electrical conductivity further expand its utility in coatings and electronic applications. These properties make TiN powder a preferred choice for demanding industrial uses.
Main Applications
TiN powder is extensively used in coatings for cutting tools, such as drills and end mills, to extend their lifespan and improve performance. Its golden-yellow color also makes it popular for decorative finishes on watches and jewelry. In aerospace, TiN coatings protect components from wear and high-temperature degradation. The powder is also employed in semiconductor manufacturing due to its electrical conductivity and diffusion barrier properties. Medical devices benefit from TiN's biocompatibility, which reduces adverse reactions in implants. These diverse applications highlight TiN powder's versatility across industries.
Safety and Storage
While TiN powder is generally stable, precautions are necessary to ensure safe handling. Avoid inhalation or skin contact, as fine particles can irritate the respiratory system and skin. Use personal protective equipment (PPE), including gloves and masks, when handling the powder. Store TiN powder in a dry, cool environment, away from moisture and oxidizing agents. Proper storage prevents degradation and maintains the material's properties. Suppliers should provide Material Safety Data Sheets (MSDS) to guide safe usage and disposal practices.
B2B Procurement Guide
When procuring TiN powder, prioritize suppliers with certifications like ISO 9001 to ensure quality and consistency. Key specifications to verify include purity (≥99%), particle size distribution, and absence of contaminants. Bulk purchases may offer cost savings, but ensure storage conditions align with supplier recommendations. Request samples for testing to confirm the powder meets your application requirements. Establish long-term relationships with reputable suppliers to secure reliable supply chains and negotiate favorable terms. Transparency in pricing and lead times is crucial for effective procurement planning.
