Calcium hydride, ib hom tshuaj muaj nyob hauv CaH2, nrog qhov hnyav molecular ntawm 42.10. Grey-dawb muaju los yog lumps, yooj yim, cov khoom siv, uas yog kev txo qis tus neeg sawv cev, desiccant, tshuaj lom neeg tshuaj xyuas reagent, thiab lwm yam. Nws tseem yog xim tsis muaj xim rhombic siv lead ua. Cov khoom lag luam yog grey, orthorhombic lossis hmoov. Rhiab noo noo. Nws tsis cuam tshuam nrog huab cua qhuav, nitrogen thiab chlorine nyob rau hauv chav tsev kub, tab sis reacts nrog cov pa roj saum toj no ntawm qhov kub kom tsim cov calcium oxide, calcium nitrous oxide thiab calcium chloride, feem. Nws tseem tuaj yeem ua tiav nrog ethanol los tsim hydrogen thiab calcium ethanol. Qhov txo qis ntawm cov hlau oxide muaj zog dua li ntawm sodium hydride lossis lithium hydride.
Kev siv cov calcium hydride
Siv hauv cov hmoov metallurgy, thaum kho kom sov mus rau 600 ~ 1000 ℃, tuaj yeem txo nrog zirconium, niobium, hafnium thiab lwm cov hlau oxides, thiab cov hmoov hlau sib cuam tshuam. Nws tuaj yeem siv ua portable portable generator, txo tus neeg sawv cev, desiccant, analytical reagent.
