Beryllium Oxide Powder Description
Beryllium oxide (BeO) yog muab rho tawm los ntawm cov minerals tshwm sim beryl thiab bertrandite, thiab tsim los ua hmoov los ntawm thermal decomposition ntawm Be(OH)2. Cov hmoov yog muag nyob rau hauv purity theem siab tshaj 99 feem pua.
Beryllium oxide (BeO) yog ib qho tshwj xeeb rau oxides vim nws muab cov khoom siv hluav taws xob zoo heev nrog cov thermal conductivity. Nws kuj yog corrosion resistant. Lub siab toxicity ntawm beryllium oxide hmoov thaum nqus tau, thiab tus nqi siab ntawm cov khoom siv raw, tau txwv nws txoj kev siv rau cov ntawv thov uas siv nws cov khoom sib txawv.
Beryllium oxide (BeO) yog ib qho hluav taws xob rwb thaiv tsev uas muaj thermal conductivity ntau dua li lwm cov hlau tsis yog pob zeb diamond, thiab tshaj li ntawm cov hlau feem ntau. Sintered beryllium oxide yog ib qho ruaj khov ceramic. Beryllium oxide yog siv nyob rau hauv lub foob pob ua ntxaij cav thiab raws li ib tug pob tshab tiv thaiv tshaj-txheej txheej ntawm aluminised telescope tsom iav.
