Calcium (Ca) General Information:
Cov cim tshuaj ntawm calcium yog Ca, atomic tooj 20, txheeb ze atomic mass 40.087, melting point 842 ° C, boiling point 1484 ° C, ntom 1.55g / cm³, thiab ionization zog 6.11 electron volts. Calcium yog siv lead ua nyiaj-dawb nrog me ntsis kev ntxhib los mos thiab cov khoom siv tshuaj lom neeg. Nws tuaj yeem tsim ib txheej ntawm oxide (calcium oxide) lossis nitride zaj duab xis (calcium nitride) rau saum npoo av los tiv thaiv kev xeb ntxiv. Nws feem ntau yog nyob rau hauv ionic xeev. los yog muaj nyob rau hauv daim ntawv compound;

Cov pob zeb tseem ceeb hauv kev lag luam muaj xws li limestone, gypsum, thiab lwm yam Calcium tuaj yeem siv los ua cov roj dehydrating tus neeg saib xyuas, metallurgical txo tus neeg saib xyuas, deoxidizing tus neeg sawv cev, thiab lwm yam rau cov alloys, thiab feem ntau yog siv hauv kev lag luam thiab kev kho mob.

Calcium (Ca) Hlau Element Txheej txheem cej luam:

Peb smelts ib yam ntawm cov hlau thiab feem ntau lwm cov ntaub ntawv siab heev rau hauv pas nrig, bar los yog phaj daim ntawv, los yog cov neeg muas zaub muab cov khoom kos duab.
Peb muag cov khoom sib txawv ntawm cov khoom siv calcium hlau los ntawm chav tsev hnyav lossis ib thooj rau kev siv sib txawv hauv cheeb tsam tshawb fawb thiab rau cov cuab yeej tshiab.

Piv txwv li: Calcium Bar, Calcium Ingot, Calcium Lump, Calcium Pellets, Calcium Target, Calcium Cube.Lwm cov duab muaj los ntawm kev thov.
