umgubo we-thorium(IV) oxide (Thorium Dioxide) (ThO2) Ubumsulwa obuncinci.99%
I-Thorium Dioxide (ThO2), ikwabizwa ngokubai-thorium(IV) oxide, ngumthombo weThorium onganyibilikiyo kakhulu kubushushu. Yinto eqinileyo ekristale kwaye idla ngokuba mhlophe okanye mthubi ngombala. Ikwaziwa ngokuba yithoria, iveliswa ikakhulu njengemveliso ephuma kwi-lanthanide kunye nemveliso ye-uranium. I-Thorianite ligama le-mineralological form ye-thorium dioxide. I-Thorium ixatyiswa kakhulu kwiglasi nakwimveliso ye-ceramic njenge-pigment etyheli ekhanyayo ngenxa yokubonakalisa kwayo okuphezulu. Umgubo we-High Purity (99.999%) we-Thorium Oxide (ThO2) kwi-560 nm. Iikhompawundi ze-oxide azikwazi ukuhambisa umbane.
