hafnium usage and synthesis |
chemical properties | solid |
general description | hafnium, is a grayish metallic colored powder. dust from dry powder may be ignited by static electricity. the dry powder reacts with moisture to produce hydrogen, a flammable gas. the heat from this reaction may be sufficient to ignite the hydrogen. hafnium does not appreciably react with large quantities of water. |
air & water reactions | highly flammable. the dry powder reacts with moisture to produce hydrogen, a flammable gas. the heat from this reaction may be sufficient to ignite the hydrogen. hafnium does not appreciably react with large quantities of water. |
reactivity profile | metals, such as hafnium metal(reactivity similar to zirconium), are reducing agents and tend to react with oxidizing agents. their reactivity is strongly influenced by their state of subdivision: in bulk they often resist chemical combination; in powdered form they may react very rapidly. thus, as a bulk metal hafnium is somewhat unreactive, but finely divided material may be pyrophoric. the metal reacts exothermically with compounds having active hydrogen atoms (such as acids and water) to form flammable hydrogen gas and caustic products. the reactions are less vigorous than the similar reactions of alkali metals, but the released heat can still ignite the released hydrogen. materials in this group may react with azo/diazo compounds to form explosive products. these metals and the products of their corrosion by air and water can catalyze polymerization reactions in several classes of organic compounds; these polymerizations sometimes proceed rapidly or even explosively. some metals in this group form explosive products with halogenated hydrocarbons. |
health hazard | fire will produce irritating, corrosive and/or toxic gases. inhalation of decomposition products may cause severe injury or death. contact with substance may cause severe burns to skin and eyes. runoff from fire control may cause pollution. |
fire hazard | flammable/combustible material. may ignite on contact with moist air or moisture. may burn rapidly with flare-burning effect. some react vigorously or explosively on contact with water. some may decompose explosively when heated or involved in a fire. may re-ignite after fire is extinguished. runoff may create fire or explosion hazard. containers may explode when heated. |
