Titanium Metal powder, Grade S (9.5 μm), dry (CAS 7440-32-6, molecular formula Ti) is an inorganic chemical supplied as a technical-grade material. It is typically a dark grey to black powder.

As getter material in vacuum technology. In the manufacture of Hg dispensers in mercury-vapor lamps. As a deoxidizing agent in powder metallurgy. For reactive solders and brazes. Titanium powders also find application in various pyrotechnic areas. Mixed with oxidizing agents they are used in initiators and air bag inflators. They are also used in the manufacture of flash cubes, for joining glass or ceramics to metals, and as a getter substance.

Typical specifications include: Auto Ignition Temperature > 400 °C; Combustion Rate 35 ± 10 sec/50 cm; Particle Size min. 99.9 % 45 μm.

Handling Instructions

Highly flammable solid. Dust explosion hazard. Fine Ti metal powder ignites reliably and burns away at high temperature within a short time. Ti metal powder is resistant to most chemical reagents but is attacked at elevated temperatures by acids and by oxidizing agents. Dilute aqueous HF attacks titanium vigorously. Keep away from flames, sparks and heat sources. Use ground connected metallic apparatus to prevent electrostatic charges causing self ignition. Vacuum drying of suspensions is not recommended. Wear gloves and protective goggles. In case of fire cover with dry sand or dry chemical/dolomite (powdered limestone). Never extinguish with water, carbon dioxide, or halocarbon. See our safety data sheet and special precautionary advice for more information on safety.
