Khoom Description
Molybdenum crucibles feem ntau yog tsim los ntawm ntshiab molybdenum hmoov nrog purity txog li 99.95%. Qhov ceev ntawm molybdenum crucible yog ntau dua 9.8g / cm3, thiab ua haujlwm kub yog 1100 degree txog 1700 degree hauv ib puag ncig lub tshuab nqus tsev.
Lub hau tsis tas yuav tsum tau, tab sis molybdenum crucibles tuaj yeem tsim ua ib txheej nrog lub hau. Lub hau tuaj yeem tuaj yeem sib txawv, xws li lub hau puag ncig nrog lub qhov hauv nruab nrab. Thaum siv los yaj cov hlau, nws yuav tsum tau muab tso rau tilted rau kev sib pauv oxygen kom tsis txhob muaj cov kua dej sab hauv los ntawm kev txaws.
