Description

Titanium Hydride (CAS NO 7704-98-5) is a critical inorganic compound widely used as a source of pure titanium and hydrogen in advanced manufacturing processes. Its ability to decompose at elevated temperatures makes it an essential precursor for powder metallurgy and pyrotechnic applications. This material is indispensable for industries requiring high-purity metal powders, including aerospace, automotive, and specialty ceramics manufacturing.

Application

• Powder Metallurgy: Acts as a crucial precursor for the production of titanium and titanium alloy powders via the hydride-dehydride (HDH) process.
• Metal Sintering & Gettering: Used as a hydrogen source and sintering aid in the production of porous metals and as a getter material to remove oxygen in vacuum systems.
• Pyrotechnics & Propellants: Serves as a high-energy fuel component in specialized pyrotechnic mixtures and solid rocket propellants due to its exothermic decomposition.
• Welding & Brazing: Employed in welding rod coatings and as an additive in brazing pastes to improve joint quality and reduce oxidation.
• Chemical Synthesis: Functions as a reducing agent in the synthesis of other metal hydrides and specialty inorganic compounds.
• Ceramics & Cermets: Used in the fabrication of advanced ceramic-metal composites (cermets) and conductive ceramics.
• Hydrogen Storage Research: Investigated as a potential material for solid-state hydrogen storage applications.

Quality Control

Our Titanium Hydride is manufactured under controlled conditions to ensure batch-to-batch consistency and high performance. Quality is verified through a series of analytical tests including hydrogen content analysis, particle size distribution (PSD), and metallic impurity profiling. A Certificate of Analysis (COA) detailing purity, particle characteristics, and chemical composition is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic and easily oxidized nature, it is recommended to store this product under an inert atmosphere (e.g., argon or nitrogen) in a moisture-free environment to maintain stability and prevent degradation. Keep container tightly sealed when not in use.
