Silicates kuj tseem siv ua iav thiab ceramics Ua li ntawd, nyuaj, cov khoom siv tsis zoo xws li xuab zeb lossis ceramic av nplaum yog rhuab mus rau qhov kub thiab txias, tig mus rau hauv cov khoom siv uas tuaj yeem ua tau. raug tsim los ua cov iav haus, piv txwv li, los yog thaum cov hmoov lead ntxiv rau cov kua nplaum--crystal iav.
Silicate siv qhov twg?
Siv. Cov ntawv thov tseem ceeb ntawm sodium silicates yog nyob rau hauv tshuaj ntxuav tes, ntawv, dej kho, thiab cov ntaub ntawv tsim kho.
Vim li cas silicates tseem ceeb?
Cov ntxhia silicate yog qhov tseem ceeb tshaj plaws mineral class vim tias lawv nyob deb ntawm cov pob zeb uas muaj ntau tshaj plawspawg no yog ua raws li silica (SiO4) tetrahedron qauv, hauv uas ib tug silicon atom yog covalently bonded rau 4 oxygen atoms ntawm cov ces kaum ntawm ib daim duab peb sab pyramid.
Dab tsi yog silicates muab ib qho siv?
5) DOUBLE CHAIN SILICATES (AMPHIBOLES)
Muaj ob hom tetrahedra: cov sib koom 3 vertices thiab cov sib koom tsuas yog 2 vertices. E.g. 1) Asbestos - Cov no yog noncombustible fibrous silicates. Lawv tau siv rau cov khoom siv rwb thaiv tsev thermal, nres hauv ob sab phlu, cov khoom siv thiab cov ntxaij lim dej
piv txwv ntawm silicates yog dab tsi?
Silicate minerals yog cov khoom siv tshaj plaws hauv ntiaj teb thiab suav nrog quartz, feldspar, mica, amphibole, pyroxene, thiab olivine.
