Brown jade, ib lub npe tseem hu ua pob zeb diamond xuab zeb, yog ib tug txiv neej xim av creted nrog alumina, carbon cov khoom, thiab peb raw cov ntaub ntawv uas yaj thiab txo nyob rau hauv hluav taws xob arc rauv, yog li nws yog lub npe no.Cov khoom xyaw tseem ceeb ntawm cov xim av jade yog Al2O3, thiab nws cov ntsiab lus yog 95.00% -97.00%, thiab muaj lwm qhov me me ntawm Fe, Si, Ti, thiab lwm yam. zoo, dav siv ntau yam, yog pheej yig, thiab yog dav siv.
Cov xim av jade yog cov khoom siv tseem ceeb nrog txhuas aluminous, coke (anthracite), thiab muaj kub kub smelting hauv hluav taws xob arc rauv.Nws yog tsim rau kev sib tsoo hlau, xws li ntau yam hlau., tuaj yeem forged cam khwb cia hlau, tawv bronze, thiab lwm yam, tuaj yeem tsim cov refractories siab heev.Cov xim av grungy muaj cov yam ntxwv ntawm siab purity, zoo crystallization, muaj zog fluidity, tsis tshua muaj hlau expansion coefficient, thiab corrosion kuj.Nrog rau ntau lub tuam txhab hluav taws kub-resistant, cov khoom muaj cov yam ntxwv ntawm kev tawg, tsis muaj hmoov, thiab tsis tawg hauv daim ntawv thov.Tshwj xeeb, nws yog ntau dua tus nqi-zoo ntawm cov xim av jasteas, uas ua rau nws zoo tshaj plaws aggregate thiab muab tub lim ntawm cov xim av jade refractory.
