Mazubin Bututun Silicon Carbide

Takaitaccen Bayani:

Ana samar da bututun bututun silikon carbide ta hanyar yin siminti ta hanyar amfani da foda mai tsarki na sub-micron mai tsarki. Ana haɗa wannan foda da kayan aikin simintin da ba na oxide ba, sannan a samar da shi zuwa siffofi masu rikitarwa ta hanyoyi daban-daban kuma a haɗa shi ta hanyar siminti a zafin da ya wuce digiri 3633 na Fahrenheit.
