Paura waikura thorium(IV) (Torium Dioxide) (ThO2) Parakore Iti rawa 99%
Te Taioraiti Torium (ThO2), e kiia ana hokiwaikura thorium(IV), he pūtake Thorium e kore e rewa i te wera. He totoka tioata, ā, he maha ngā wā he mā, he kōwhai rānei te tae. E mōhiotia ana ko te thoria, ka puta mai i te nuinga o te wā hei hua o te hanga lanthanide me te uranium. Ko te Thorianite te ingoa o te āhua mineralogi o te thorium dioxide. He tino uara te Thorium i roto i te hanga karāhe me te uku hei tae kōwhai kanapa nā te mea he tino pai te whakaata. Teitei te Parakore (99.999%) te Paura Thorium Oxide (ThO2) i te 560 nm. Kāore ngā matū waikura e kawe hiko.
