Cristobalite yog mineral polymorph ntawm silica uas yog tsim los ntawm qhov kub siab heev. Nws yog siv nyob rau hauv kev kho hniav raws li ib feem ntawm alginate impression cov ntaub ntawv raws li zoo raws li ua qauv ntawm cov hniav. Nws muaj tib yam tshuaj formula li quartz, SiO2, tab sis tus qauv siv lead ua sib txawv.
Puas tridymite muaj silica?
Tridymite, silica ntxhia, daim ntawv ruaj khov ntawm silica (silicon dioxide, SiO2) ntawm qhov kub ntawm 870 ° thiab 1, 470 ° C (1, 598 ° thiab 2, 678 ° F); Nyob rau hauv qis kub nws hloov mus rau high-quartz, siab dua mus rau cristobalite. Nws muaj peb qhov kev hloov kho: high-tridymite, nruab nrab-tridymite, thiab qis-tridymite.
Dab tsi yog qhov txawv ntawm quartz thiab cristobalite?
yog tias quartz yog (mineralogy) cov ntxhia ntau tshaj plaws nyob rau hauv lub ntiaj teb saum npoo av, ntawm cov tshuaj muaj pes tsawg leeg silicon dioxide, sioxygen|o2 nws tshwm sim hauv ib Muaj ntau hom, ob qho tib si crystalline thiab amorphous pom nyob rau hauv txhua qhov chaw thaum cristobalite yog (mineral) ib qho ntxhia ntawm pob zeb volcanic uas solidified ntawm siab …
