ST.CERA Giraanta Diiradda Dhoobada ee Semiconductor-ka ah ee gaarka loo leeyahay
Waxay ka samaysan tahay nadiifnimo sare (ka sarreysa 99.5%) dhoobada alumina, oo ay samaysay cadaadis isostatic qabow oo lagu simi karo heerkul sare, ka dibna si sax ah loo farsameeyay oo loo safeeyey, qaybaha kaydka dhoobada waxay buuxin karaan shuruudo adag oo qalabka semiconductor ah oo leh astaamo u gaar ah iska caabbinta xirashada, iska caabbinta daxalka, ballaarinta kulaylka oo hooseeya, iyo dahaarka.
Iyada oo leh astaamo u adkeysiga heerkulka sare, iska caabbinta daxalka, iska caabbinta xoqidda iyo dahaarka, dhoobada ayaa ka shaqayn karta noocyo badan oo qalabka wax soo saarka semiconductor-ka ah oo leh heerkul sare, faakiyuum ama gaas daxal leh muddo dheer.
Waxaa laga sameeyay budada alumina saafi ah oo sareysa, oo lagu farsameeyay cadaadis isostatic qabow, sintering heerkul sare iyo dhammaystir sax ah, waxay gaari kartaa dulqaad cabbir ilaa ± 0.001 mm, dhammaystirka dusha sare Ra 0.1, iska caabbinta heerkulka 1600℃.
