I-Thorium Dioxide (ThO2), ikwabizwathorium (IV) oxide, ngumthombo weThorium onganyibilikiyo kakhulu. Yikristale eqinileyo kwaye ihlala imhlophe okanye ityheli ngombala. Ikwabizwa ngokuba yi-thoria, iveliswa ikakhulu njengemveliso ye-lanthanide kunye ne-uranium. I-Thorianite ligama le-mineralogical form ye-thorium dioxide. I-Thorium ixatyiswe kakhulu kwimveliso yeglasi kunye ne-ceramic njengebala eliqaqambileyo elityheli ngenxa yokubonakala kwayo okuphezulu Ucoceko oluphezulu (99.999%) iThorium Oxide (ThO2) Powder kwi-560 nm. Iikhompawundi zeoksijini azihambisani nombane.
