Sg chomic grindicis giraangiraha buluuga ah ee buluugga ah ee boodhka 'cyrindrical Booggasho
Sg Cilmiga polycrystalline aluminina qolof ah qaab dhismeedka qurxinta. Waxay ku siineysaa wax qabad aad u sareysa oo ka badan alumina caadiga ah ee shixnaada ah, maxaa yeelay geeska goynta ayaa ah jahwareer ahaan awoodda mikroscoopically iyo mid ka sareeya ayaa lagu ilaaliyaa dusha sare iyo shiidka frindrical. Claing giraangiraha laga sameeyay muddo dheer oo leh cimri dheer iyo nolol dheer, oo ah 5-10 jeer marka loo eego giraangiraha shiidi ee loo yaqaan 'crount gired gired gelquimina' iyo isku-darka Marka laga hadlayo giraangiraha caadiga ah ee aluminide aluminide, oo is-fiiqan oo is-daaweyn ah ayaa ka soo bixisa geesaha fiiqan ee aaladda oo dhinta.
