Āhuatanga ā-tinana, matū hoki Te paura ma.
te paura ma me te kakano ngohengohe, te kakara me te reka, te kaha huna me te kaha tae, te rewa 1560~1580 ℃. Kore ki te wai, waimeha waikawa pararopi, whakarewa pararopi, hinu, paku wairewa ki te kawakore, wairewa ki te waikawa pungatara mau. Ka huri te kowhai ina whakamahana, ka ma i muri i te whakamatao. Ko te Rutile (R-momo) he 4.26g/cm3 te kiato me te 2.72 te taupū whakaahuru. R momo titanium hauhā he pai huarere ātete, ātete wai me te kore ngāwari ki ngā āhuatanga kōwhai, engari paku rawakore ma. Ko te Anatase (Momo A) he 3.84g/cm3 te kiato me te 2.55. Patohia te titanium dioxide he iti te parenga marama, kaore i te aukati i te huarere, engari he pai ake te ma. I nga tau kua pahure ake nei, kua kitea ko te nano-rahi te ultrafine titanium dioxide (te nuinga o te 10 ki te 50 nm) he waahanga Semiconductor, he nui te pumau, he maamaa teitei, he mahi teitei me te kaha o te whakamararatanga, kaore he paitini me te paanga o te tae.
Whakamahi Ka whakamahia i roto i te peita, te mangumangu, te kirihou, te rapa, te pepa, te muka matū me etahi atu ahumahi; Ka whakamahia mo te whakarewa i te hiko, te whakamahine i te titanium me te hanga titanium dioxideKo te Titanium dioxide (Nano) e whakamahia nuitia ana i roto i nga miihini mahi, nga whakakorikori, nga mea whakapaipai me nga taonga whakaahua, penei i te ma. whakangao parakore. Ko te poaka ma te mea tino kaha, he pai te mana huna me te tere o te tae, e tika ana mo nga hua ma opaque. Ko te momo rutile he tino pai mo te whakamahi i nga hua kirihou o waho, ka taea te tuku i te pai o te marama. Ko te Anatase te nuinga mo nga hua o roto, engari he maamaa te kikorangi, he maamaa teitei, he mana huna nui, he tae kaha me te marara pai. Titanium hauhā e whakamahia whānuitia rite peita, pepa, rapa, kirihou, tohu, karaihe, poke, mangumangu, tae wai me te hinu tae tae hinu, ka taea hoki te whakamahi i roto i te whakarewa, reo irirangi, uku, hiko.
