Yini i-lanthanum oxide esetshenziselwa?
Njengomhlaba ongavamile womhlaba, iLanthanum isetshenziselwa ukwenza amalambu e-carbon arc asetshenziswa embonini yezithombe ezinyakazayo ukuze kukhanyiselwe izibani nama-projektha.Lanthanum oxideizosetshenziswa njengokuhlinzekwa kwe-lanthanum. ILanthanum oxide ithola ukusetshenziswa: izibuko ze-Optical, i-LA-CE-TB phosmors yama-fluorescent, FCC Catalysts. Ilungele izinhlelo zengilazi, i-optic ne-ceramic, futhi isetshenziswe kwezinye izinto ze-ferroeelectric, futhi iyisiphepho sama-catalysts athile, phakathi kokunye ukusetshenziswa.
