Cov xim kub kub uas tuaj yeem tiv taus kub oxidation thiab corrosion nruab nrab. Kev lag luam kub txheej txheej feem ntau nyob rau hauv 100 ℃ -1800 ℃, feem ntau ntawm cov xim kub kub siv cov tshuaj kub kub, cov xim yuav tsum muaj nyob rau hauv ib puag ncig tuaj yeem ua tiav cov khoom siv lub cev ruaj khov (tsis muaj shedding, tsis muaj npuas, tsis tawg, tsis muaj hmoov, tsis muaj xeb, cia me ntsis discoloration). Kev xaiv dav dav ntawm cov nyiaj lossis xim dub, ob xim yog qhov ruaj khov, tsis yooj yim rau ploj ntawm qhov kub thiab txias. Titanium dioxide muaj thermal stability zoo heev, kub resistant 350-400 ℃ tsis hloov xim thiab 600 ℃ variable rau tan, mus txog 1200 ℃ mus rau 1300 ℃ nws yuav irreversible tsaus xim av.
Thaum tshav kub kub tsis kam ntawm zinc oxide nyob rau hauv cov xim dawb yog 250 mus rau 300 ℃, lithopone yog haum rau lub sij hawm ntev tshav kub ntawm 250 ℃.
Nyob rau hauv cov xim dub, lub sij hawm ntev kub siv rau cov pa roj carbon dub ntawm 250 ℃, yog tias qhov kub siab tshaj 300 ℃, cov xim yuav ploj mus. Lub sij hawm ntev tshav kub tsis kam ntawm graphite hmoov thiab manganese dioxide rau 300 ℃.
Cov xim liab hauv cov hlau oxide liab thiab cadmium liab rau 250 ℃ thaum tshav kub kub mus ntev.
Daj, daj thiab daj cadmium strontium lub sij hawm ntev kub tuaj yeem tiv taus 200 ℃.
