Exposure and Risk Assessment For Cyanide - EPA

Other metal cyanide complexes—silver, zinc, and copper—were more toxic than other complexes, apparently because of the higher toxicity of the ion present. In all test cases, except one, effective concentrations were higher than those of simple cyanides tested under the same conditions (Lipshuetz and Cooper 1955, Doudoroff 1956).

Science made alive: Chemistry/Experiments

Praseodymium is a very reactive metal, which reacts with water. It does not react as vigorous as calcium metal, but still, when left in contact with water for a somewhat longer time, it will be converted to hydroxide completely. Praseodymium only exists in the +3 oxidation state in aqueous solution and then its color is pale green.

Self-sustaining reactions induced by ball milling - …

1/1/2002· Abstract. Ball milling induces self-sustaining reactions in many sufficiently exothermic powder mixtures. The process begins with an activation period, during which size reduction, mixing, and defect formation take place. The MSR (mechanically induced self-propagating reaction) is ignited when the powder reaches a well defined critical state.
