He aha te whakamahinga o te Thorium Dioxide (ThO2)?
Kua whakamahia te hauhā thorium (thoria) i roto i ngā uku pāmahana-tiketike, ngā kohao hau, te wahie karihi, te pupuhi mura, ngā oko whakarewa, te karāhe whatu kore-silicia, te whakaterenga, ngā miro i roto i ngā rama mura, ngā katote i roto i ngā ngongo irahiko me ngā irahiko whakarewa-pewa.Ngā wahie karihiKa taea te whakamahi i te hauhā thorium (thoria) i roto i ngā tauhohenga karihi hei pire wahie uku, kei roto i ngā tokotoko wahie karihi kua whakakikoruatia ki ngā koranu zirconium. Ehara te thorium i te mea pakaru (engari he "momona", ka whakaputa uri i te uranium-233 pakaru i raro i te pupuhi neutron);Ngā koranuE whakamahia ana te thorium dioxide hei whakau i roto i ngā irahiko tungsten i roto i te whakarewa TIG, ngā ngongo irahiko, me ngā miihini tāpine hau rererangi.WhakaohoKāore rawa he uara o te hauhā thorium hei whakakorikori arumoni, engari kua rangahaua paitia ēnei whakamahinga. He whakakorikori i roto i te hanganga mowhiti nui o Ruzicka.Ngā kaihoko whakawhiti irahikoKo te thorium dioxide te matū matua o te Thorotrast, he taputapu irahiko i whakamahia mō te angiography roro, heoi, ka puta he momo mate pukupuku onge (hepatic angiosarcoma) i muri i ngā tau maha i te whakahaerenga.Te hanga karaiheIna tāpirihia ki te karāhe, ka āwhina te hauhā thorium ki te whakanui ake i tōna taupū whakaata me te whakaiti i te mararatanga. Ka kitea te whakamahinga o taua karāhe i roto i ngā karāhe kounga teitei mō ngā kāmera me ngā taputapu pūtaiao.
