Formula ntawm Calcium Nitride

(Cov qauv ntawm Calcium Nitride)

Thaum nws los sau cov qauv ntawm ib qho ionic compound, muaj ob txoj cai kom nco ntsoov. Ua ntej, ib txwm sau cov atom zoo nyob rau hauv kev txiav txim. Qhov thib ob, xyuas kom meej tias cov atoms tsis zoo sau ntawv kawg.

Calcium nitride yog ib qho inorganic compound nrog cov tshuaj formula Ca3N2. Nws muaj cov hmoov liab-xim av ua los ntawm calcium thiab nitrogen. Nws yog ib qho reactive nitride ion thiab tuaj yeem siv los tsim ntau yam khoom sib txawv.

Synthesis ntawm calcium nitride (Ca3N2) yog ua tiav los ntawm cua sov hlau calcium nyob rau hauv lub xub ntiag ntawm nitrogen. Cov txheej txheem no tau paub txij li kev ua haujlwm ntawm Henri de Moissan hauv xyoo 1898, thiab yog cov txheej txheem tseem ceeb rau kev tsim cov khoom siv lead ua ib leeg.

Thaum lub sij hawm synthesis ntawm calcium nitride, hlau calcium yog rhuab mus rau 450deg C nyob rau hauv ib tug kwj ntawm ntshiab nitrogen thiab ces nitrided tom qab 3-4 teev. Cov calcium nitride npaj yog dub ntawm 350degC, milky dawb ntawm 350 txog 1150degC, thiab kub daj saum 1150degC.

Cov nitride no tau yooj yim txheeb xyuas vim tias nws cuam tshuam nrog dej los tsim calcium hydroxide thiab ammonia. Nws yog ib qho khoom siv dav siv hauv kev tsim lub teeb-emitting diode phosphors.

Ntxiv nrog rau nws siv nyob rau hauv cov synthesis ntawm ntau yam tshuaj sib txuas, calcium nitride kuj yog siv rau kev sim kuaj. Nws yog pheej yig thiab yooj yim kom tau, ua rau nws yog ib qho kev xaiv zoo rau kev tshawb fawb txog kev tshawb fawb.

Kev sib xyaw ntawm calcium nitride yog cov txheej txheem ua tau zoo uas tuaj yeem ua tau siv lub cuab yeej xws li cov sawv cev hauv FIG. 4. Nws muaj ib lub tank 19 uas muaj zinc-calcium alloy nyob rau hauv huab hwm coj feem ntawm ib feem peb zinc rau ob feem peb calcium, cov alloy raug pressurized los ntawm argon los ntawm ib tug thib ob tank 19. Lub molten alloy yog sprayed nyob rau hauv daim ntawv ntawm tee rau hauv lub reactor 6 los ntawm ib tug injector (5) thiab yog sau nyob rau hauv ib tug collector chav tsev 7 (Daim duab 2) nyob rau hauv lub qis ib feem ntawm lub reactor.
