Ugu badnaan iyadoo la adeegsanayo dhoobada maaddada insulata ee qalabka koronto-dhaliyeyaasha, iyo qaab-dhismeedkeeda aasaasiga ahi waa isku-darka dhoobada iyo iskutallaabta korantada gudaha. Qalabka dhoobada ee dhowr nooc. Maaddaama aan waxyeello lahayn tixgelinayso alaabada elektiroonigga ah ee aan lahayn macdanta "lead", isugeyn sare ee koronto-dhaliyaha 'PB' (Lead) si looga baxo aagga mashiinnada dhoobada, oo hadda inta badan la isticmaalo TiO2 (titanium dioxide), BaTiO3, CaZrO3, (calcium zirconate). Cabbir yar, awood weyn, iska caabin kuleyl wanaagsan, oo ku habboon wax soo saar tiro badan iyo qiimo hooseeya marka la barbar dhigo qalabka kale ee wax qabta.
