Alaabooyinka waxaa si weyn loogu isticmaalaa giraangiraha dhoobada, alaabada aluminium sare, kubbadda aluminium aluminium, kiln warshadaha, dhoobada elektiroonigga ah, dhoobada korantada sare, alaabada fayadhowrka, dhoobada maalinlaha ah, daawaha nitride iyo dhoobada xumbo iyo warshadaha kale.
Iska caabbinta xidhashada ee walxaha Si3N4-SiC waa 3.13 jeer ka badan birta xidhashada u adkaysata (Crl5Mo3), miisaankuna waa 1/3 oo kaliya ee birta u adkaysata (Crl5Mo3).
Qiimaha dhimista tayada iska caabbinta daxalka ee Si3N4-SiC iyo calcium carbide iyo alumina ee xalalka kala duwan waa sida soo socota:
Xalka tijaabada | Heerkulka ("C) | Si3N4-SiC | dhoobada caadiga ah | Aluminium carbide | Aluminium oxide |
