二水素チタン(II) 化学特性,用途語,生産方法

• 外観

  灰黒色の粉末

• 使用上の注意

  不活性ガス封入

• 化学的特性

  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.

• 物理的性質

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

• 使用

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

• 製造方法

  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.

• 一般的な説明

  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.

• 空気と水の反応

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

• 反応プロフィール

  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.

• 危険性

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

• 健康ハザード

  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.

• 火災危険

  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.
