Synthetic liab hlau oxide

Cov xim ntau tshaj plaws hauv ceramics yog hluavtaws liab hlau oxide, uas muaj cov hlau ntau tshaj. Nws yog cov khoom lag luam uas muaj cov hmoov mos thiab zoo heev uas tsim los ntawm kev sib tsoo ore los yog ua kom sov ferrous / ferric sulphate lossis ferric hydroxide. Tag nrho cov hlau decompose thiab tsim cov xim zoo sib xws hauv glazes thiab av nplaum lub cev thaum tua.
Liab hlau oxide tuaj nyob rau hauv ntau yam ntxoov xws li los ntawm lub teeb ci liab mus rau ib tug sib sib zog nqus liab maroon. Cov no ib txwm raug xaiv los ntawm qhov ntsuas txij li ntawm 120-180 (tus naj npawb no yuav tsum nyob ntawm lub hnab los ntawm cov chaw tsim khoom, cov xim tsaus yog cov lej siab dua), tab sis hauv cov ceramics, cov qib sib txawv no yuav tsum muaj hluav taws kub zoo sib xws vim lawv muaj tib yam hlau. Cov xim sib txawv yog tshwm sim los ntawm kev sib tsoo.
