41. The very high toxicity of aluminium phosphide is attributed to the phosphine content and is not related to aluminium. 42. "' Indium phosphide "'( InP ) is a binary semiconductor composed of indium and phosphorus. 43. Sodium phosphide is also employed commercially as a catalyst in conjunction with zinc phosphide and aluminium phosphide for polymer production. 44. Sodium phosphide is also employed commercially as a catalyst in conjunction with zinc phosphide and aluminium phosphide for polymer production. 45. Sodium phosphide is also employed commercially as a catalyst in conjunction with zinc phosphide and aluminium phosphide for polymer production. 46. Researchers at the University of Alberta have successfully synthesized colloidal zinc phosphide , and are the first to do so. 47. Communications LEDs are most commonly made from Indium gallium arsenide phosphide ( InGaAsP ) or gallium arsenide ( GaAs ). 48. Various indium compounds ( indium arsenide, indium phosphide ) are also being used in LEDs and solid state laser diodes. 49. Zinc phosphide is typically added to rodent baits in a concentration of 0.75 % to 2.0 %. 50. Acute aluminium phosphide poisoning ( AAlPP ) is a large, though under-reported, problem in the Indian subcontinent.
