Dulmar guud ee gariiradda birta ah ee qabow

Gariiradda duuban ee qabowgu waxay ka samaysan tahay gariiradda duuban ee kulul. Habka qaboojinta duuban, gariiradda kulul ee duuban ayaa lagu rogrogaa hoos heerkulka recrystallization, iyo guud ahaan birta duuban waxaa lagu rogaa heerkulka qolka. Xaashiyaha birta ah ee ay ku jirto maadada silikoonku waxay leedahay jilicsanaan hoose iyo caag yar, waxayna u baahan tahay in lagu sii kululeeyo ilaa 200 °C ka hor inta aan la duubin qabowga. Maadaama gariiradda qabowga aan la kululayn inta lagu jiro habka wax-soo-saarka, ma jiraan cillado ay ka mid yihiin godad iyo oksijiinta birta oo inta badan laga helo duubista kulul, tayada dusha sare iyo dhammaadka ayaa wanaagsan.
