数据库记载的用途

  • Used to prepare rare metals (reduction of metal oxides) and to generate hydrogen; Also used as a drying agent and in organic syntheses; [Merck Index]
  • Metal Extraction and Refining [Category: Industry]
  • Reducing agent, drying agent, analytical reagent in organic chemistry, easily portable source of hydrogen, cleaner for blocked-up oil wells
  • To prepare rare metals by reduction of their oxides; as a drying agent for liquids and acid esters; to generate hydrogen; ... in organic synthesis
  • Calcium hydride is produced industrially by synthesis from the elements /calcium and hydrogen/ at 400 °C and atmospheric pressure ... The reaction is strongly exothermic and is controlled by means of the hydrogen feed rate. The commercial product contains 90-96% CaH2.
  • Calcium hydride is prepared on a commercial scale by heating calcium metal to about 300 °C in a high alloy steel, covered crucible under 101 kPa (1 atm) of hydrogen gas. Hydrogen is rapidly absorbed at this temperature and the reaction is exothermic.
