Yuav ua li cas los tsim High-purity Silicon Carbide?

Hauv kev tsim cov silicon carbide, cov txheej txheem ib txwm siv yog sib tov silica nrog coke thiab cua sov rau hauv qhov cub impedance; Los yog cov silica hmoov thiab cov pa roj carbon sib xyaw ua ke hauv qhov sib piv ntawm ntau tshaj 1 mus rau 3 rau granulation thiab rhuab nyob rau hauv lub cub tawg tas li; Cov silicon carbide tsim los ntawm ob txoj kev no feem ntau muaj qee yam impurities, uas cuam tshuam ncaj qha rau daim ntawv thov cov nyhuv ntawm silicon carbide. Txawm li cas los xij, cov teeb meem zoo li no yuav tsis tshwm sim hauv daim ntawv thov ntawm high-purity silicon carbide.

Txhawm rau tsim cov purity silicon carbide, nws yog ib qho tsim nyog yuav tsum tau ua ntej sib tov silica hmoov thiab carbon hmoov rau granulation, ces sib tov granulation nrog granular carbon cov ntaub ntawv, sov nws nyob rau hauv ib tug uas tsis yog-oxidizing cua tshaj 1600 degree, yog li ntawd feem ntau ntawm silicon. dioxide nyob rau hauv granulation reacts nrog carbon los tsim gaseous silicon oxide. Lub gaseous silicon oxide ntxiv reacts nrog cov granular carbon cov ntaub ntawv los tsim silicon carbide, thiab cov impurities nyob rau hauv lub qub granulation, tom qab tshem tawm cov impurities, High purity silicon carbide yog tsim. High purity silicon carbide tuaj yeem siv los ua cov khoom siv raw rau sintering, hluavtaws resin muab tub lim thiab txheej txheej rau kev hnav yooj yim ntawm cov khoom siv hlau. Nws yog ib yam khoom zoo heev nyob rau hauv kev ua lag luam.
