TITANIUM HYDRIDE Usage And Synthesis

Chemical Properties

grey to black powder

Chemical Properties

Titanium Hydride, TiH2, is a brittle, metallic-gray solid, density 3.8 g/cm3, which produces 448 mL H2 at STP per gram TiH2. Titanium hydride powder is stable at room temperature and inert to water and most chemical reagents. Titanium hydride is used as a source for Ti powder, alloys, and coatings; as a getter in vacuum systems and electronic tubes; as a sealer of metals; and as a hydrogen source.

Physical properties

Grayish-black metallic powder; stable in air; density 3.75 g/cm3; decomposes at 450°C with evolution of hydrogen; insoluble in water.

Uses

Additive in powder metallurgy; getter for oxygen and nitrogen in electronic tubes; wetting agent for ceramic to metal seals; source of pure hydrogen.

Preparation

Titanium hydride is prepared by heating titanium dioxide with calcium hydride at 600°C in the presence of hydrogen
Also, the hydride may be prepared by heating tianium metal with hydrogen at elevated temperatures.

General Description

A white to light colored solid. Insoluble in water and denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. May ignite and burn with an intense flame if exposed to high temperatures or flame.

Air & Water Reactions

Highly flammable. Pyrophoric in dust form [Bretherick 1979. p. 104]. Insoluble in water.

Reactivity Profile

Hydrides, such as TITANIUM HYDRIDE, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.

Hazard

Flammable, dangerous fire risk, dust may explode in presence of oxidizing agents.

Health Hazard

Oxides from metallic fires are a severe health hazard. Inhalation or contact with substance or decomposition products may cause severe injury or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

May react violently or explosively on contact with water. Some are transported in flammable liquids. May be ignited by friction, heat, sparks or flames. Some of these materials will burn with intense heat. Dusts or fumes may form explosive mixtures in air. Containers may explode when heated. May re-ignite after fire is extinguished.
