Cov ntaub ntawv lub cev
1. Cov yam ntxwv: Liab lossis tsaus liab Octagonal cubic Crystal System Crystalline Hmoov. Nyob rau hauv cov huab cua yuav tig sai sai, nyob rau hauv cov huab cua ntub maj oxidized rau dub tooj liab tooj liab oxide.
2. Qiv (G /M³, 25/4 ℃): 6.0
3. Tus txheeb ze Vapor Density (G / cm³, cua = 1): 4.9
4. Melting point (ºC): 1235
5. Hau taw tes (ºC, atmospheric siab): 1800
6. Refctive Performance index: 2.705
7. Flash taw (ºC): 1800
8. Solubility: Insoluble hauv dej thiab haus cawv, soluble hauv hydroc acid, ammonium chloride, ammonia, me ntsis soluble hauv nitric acid. Yaj hauv hydrochoforic acid los tsim cov hmoov dawb crystalline ntawm cuprous chloride. Thaum ntsib nrog dilute sulfuric acid thiab dilute acid los tsim tus tooj liab liab. Hloov xiav sai sai hauv huab cua. Soluble hauv concentrated alkali, ferric chloride thiab lwm txoj kev daws teeb meem.
Cia Txoj Kev
1. Khaws rau hauv qhuav, zoo - cov tsev rau khoom siv ua cua, tsis sib xyaw nrog oxidizer. Thawv yuav tsum tau muab ntim rau kev tiv thaiv kev sib cuag nrog huab cua mus rau hauv tooj liab oxide thiab txo cov nqi ntawm kev siv. Nws yuav tsum tsis txhob muab khaws cia thiab sib xyaw nrog cov kua qaub muaj zog, muaj zog alkali thiab cov khoom noj.
2. Thaum thauj khoom thiab thau khoom, nws yuav tsum tau kho maj mam tiv thaiv cov pob los ntawm kev puas ntsoog.
Synthesis txoj kev
Qhuav hniav hmoov yog sib xyaw nrog tooj liab oxide tom qab tshem tawm impiner, thiab xa mus rau hauv cov calciner yuav tsum tau rhuab rau hauv cov pa oxide. Tom qab coj tawm, siv cov hlau nplaum kom nqus cov tshuab impurities, thiab tom qab ntawd crushed rau 325 los tsim cov khoom cupous oxide cov khoom tiav. Yog tias tooj liab sulfate yog siv los ua cov khoom siv roj hmab, lub tooj hauv tooj liab sulfate yog thawj cov tshuaj tiv thaiv zoo ib yam li cov khoom siv roj.
Xwm thiab Ruaj Khwv
1. Yuav tsis decompose yog siv thiab khaws cia raws li cov lus qhia tshwj xeeb, tsis txhob paub cov teeb meem, zam oxides, noo noo / av noo, huab cua.2. Tsis tsim cov ntsev tooj liab nrog tshuaj sulfuric thiab nitric acids. Hloov xiav sai sai hauv huab cua. Soluble hauv concentrated alkalis, ferric chloride thiab lwm txoj kev daws teeb meem. Heev toxic.
3. Txawm hais tias cov pa oxide ruaj khov nyob rau hauv cov huab cua qhuav, nws yuav maj mam oxidize kom tau tooj liab oxide, yog li nws tuaj yeem siv los ua deoxidizer; Tsis tas li ntawd, nws yog qhov yooj yim raug txo kom nws yog xim hlau nrog tus neeg sawv cev txo tus neeg sawv cev. Cov tshuaj pleev cov kua dej tsis txaus hauv dej, thiab cov tshuaj ammonia concentrated hydrohalic acid los tsim cov nyom thiab yaj, yooj yim heev kom yaj hauv alkaline aqueous daws.
