Cerium oxydatum Application
1. Cerium oxydatum, quod et Ceria vocatur, late patet in vitreis, ceramicis et catalyst fabricandis.
2. In industria vitrea efficacissima censetur politio vitri agentis ad subtilitatem poliendam opticam.
3. Adhibetur etiam vitreum decolorare per ferrum in statu ferreo.Facultas vitreae Ceri-emissae ad arcendos ultra lumen violaceum adhibitum est in fabricandis vitreis medicinis et aerospace fenestris.
4. Solet etiam ne polymerorum in sole obtenebrare et decolorationem televisificae vitri supprimere.
5. Ad partes opticas applicatur ad emendandum faciendum.Alta puritas Ceria adhibentur etiam in phosphoro et crystallo dopant.
