TiO2 (rutile) belongs rau tetragonal crystal system. cov
Chemical zog thiab siv
Titanium dioxide (TiO2) yog ib qho inorganic compound uas tsis tshua muaj tshuaj lom neeg ruaj khov thiab acidic zog. Nws yog amphoteric oxide nrog cov tshuaj ruaj khov thiab tsis muaj tshuaj lom. Nws yog dav siv nyob rau hauv coatings, plastics, papermaking, printing inks, tshuaj fibers, roj hmab, tshuaj pleev ib ce thiab lwm yam lag luam. Titanium dioxide muaj lub siab melting point thiab tseem siv los ua cov iav refractory, glazes, enamels, av nplaum thiab cov khoom siv ntsuas kub-resistant.
Crystal qauv
Cov qauv siv lead ua hom titanium dioxide muaj xws li rutile, anatase thiab brookite. Ntawm lawv, rutile thiab anatase belongs rau tetragonal crystal system. Rutile crystals yog slender, prismatic, thiab feem ntau twinned; Anatase feem ntau yog kwv yees li niaj zaus octahedron. Rutile muaj ib chav tsev me me lattice, muaj kev ruaj ntseg ntau dua thiab cov txheeb ze ntom ntom, muaj qhov siab dua refractive index thiab dielectric tas li, thiab muaj thermal conductivity qis dua.
