Feem ntau silicates yog tsim ua pob zeb molten txias thiab crystallizes..
silicates tuaj qhov twg?
Dej txav mus los ntawm cov khoom siv ntuj tsim yuav yaj me me ntawm ntau yam silicate minerals, ua silicates ib qho kab mob sib kis ntawm dej ntau. Cov txheej txheem ntawm lub cev thiab tshuaj lom neeg huab cua kuj tsim ntau cov khoom me me lossis colloids ntawm silicate minerals.
Dab tsi yog silicates ua los ntawm?
Lub hauv paus chav nyob hauv tag nrho cov qauv silicate yog silicon-oxygen (SiO 4) 4– tetrahedron. Nws yog tsim los ntawm lub hauv paus silicon cation (Si4 +) sib raug zoo rau plaub oxygen atoms uas nyob rau ntawm kaum ntawm ib txwm tetrahedron.
Peb puas muaj silicates hauv ntiaj teb?
Silicates yog nyob deb ntawm cov zaub mov uas muaj ntau tshaj plaws hauv ntiaj teb cov pob zeb thiab mantle, ua 95% ntawm cov crust thiab 97% ntawm mantle los ntawm feem ntau kwv yees.
Natural silicate yog dab tsi?
Feem ntau ntawm cov ntuj silicates, xws li micas, feldspar, Beryl, Wollastonite, thiab lwm yam yog tsim los ntawm solidification ntawm magma (igneous keeb kwm). Qee cov silicates kuj tsim nyob rau hauv cov pob zeb metamorphic xws li schists thiab gneisses.
