Te Whakamahinga o te waikura Praseodymium
1: Ko te Praseodymium Oxide, e kiia ana ko Praseodymia, e whakamahia ana hei tae i ngā karāhe me ngā enamel; ina konatunatua ki ētahi atu rauemi, ka puta he tae kōwhai ma i roto i te karāhe e te Praseodymium.
2: He wāhanga o te karāhe didymium he tae mō ngā mōhiti a te kaiwero, he tāpiringa nui anō hoki mō ngā tae kōwhai Praseodymium.
3: Kua whakamahia te waikura Praseodymium i roto i te wairewa totoka me te ceria, me te ceria-zirconia rānei, hei whakakorikori waikura. 4: Ka taea te whakamahi hei hanga i ngā aukume kaha-nui e mōhiotia ana mō tō rātou kaha me te roa.
