  • Method of making high oxygen chromium target
    Patent number: 5561833
    Abstract: To provide a raw material for high oxygen chromium targets containing oxygen in a form capable of effectively preventing the dust ejection phenomenon. A raw material for high oxygen chromium targets comprising chromium crystalline particles dispersed in metallic chromium wherein at least a portion of the surface of all the crystals constituting the oxide crystalline particles is in contact with the matrix of the metallic chromium. A method of producing a raw material for high oxygen chromium targets comprising chromium oxide crystalline particles dispersed in metallic chromium characterized by heat-treating metallic chromium containing a solid solution of oxygen or oxide particles as a starting material, and precipitating or crystal-growing the oxygen or oxide particles as chromium oxide crystalline particles having a particle size of 0.1 to 100 .mu.m, thereby obtaining a raw material for chromium targets.
