Ka hoʻohana ʻana o Praseodymium oxide
1: ʻO Praseodymium Oxide, i kapa ʻia ʻo Praseodymia, i hoʻohana ʻia e kala i nā aniani a me nā enamels; ke hui pū ʻia me kekahi mau mea ʻē aʻe, hana ʻo Praseodymium i kahi kala melemele maʻemaʻe ma ke aniani.
2: ʻO ka ʻāpana o ke aniani didymium he mea kala no nā maka aniani o ka welder, ʻoiai he mea hoʻohui koʻikoʻi o nā puaʻa melemele Praseodymium.
3: ʻO Praseodymium Oxide i ka hopena paʻa me ka ceria, a i ʻole me ka ceria-zirconia, ua hoʻohana ʻia e like me nā catalysts oxidation. 4: Hiki ke hoʻohana ʻia e hana i nā mea mana kiʻekiʻe i kaulana no ko lākou ikaika a paʻa.
