1. What is Nickel Silicide (Ni₂Si) Powder?

Nickel Silicide (Ni₂Si) is a nickel-silicon intermetallic compound containing two nickel atoms for every silicon atom. It is used in electronic materials and advanced materials research because of its electrical and thermal properties.

2. What is Ni₂Si Powder used for?

Ni₂Si powder is used for semiconductor research, electronic materials, thin-film development, powder metallurgy, thermal spray, diffusion studies, and specialized materials research.

3. What is the difference between Ni₂Si and NiSi?

Both are nickel silicides but have different stoichiometries. Ni₂Si contains a 2:1 nickel-to-silicon ratio, while NiSi contains approximately equal amounts of nickel and silicon. Their crystal structures and electrical properties also differ.

4. What particle sizes are available?

REG Metals can source fine, micron, and submicron Ni₂Si powders, with customized D10, D50, and D90 particle-size distributions available depending on the manufacturing process.

5. Can high-purity Ni₂Si be supplied?

Yes. 99%, 99.5%, 99.9%, and 99.99% purity grades can be sourced, subject to availability and the required impurity specification.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting Ni₂Si purity, phase composition, nickel/silicon ratio, particle-size distribution, oxygen content, trace-metal impurities, and other applicable specifications.
