Silicon dioxide tshwm sim yuav luag txhua qhov hauv ntiaj teb. Nws yog ib qho tseem ceeb tshaj plaws thiab muaj cov oxides ntau nyob hauv ntiaj teb, suav txog li 60% qhov hnyav ntawm lub ntiaj teb cov hmoov av li silica nws tus kheej lossis ua ke nrog lwm cov hlau oxides hauv silicates. Feem ntau nws pom muaj xuab zeb hauv dej hiav txwv loj thiab ntug dej, lawv lub txaj, cov suab puam, pob zeb, thiab cov zaub mov.

Silicon dioxide muaj nyob hauv ntau yam qauv: polymorphic crystalline silica, hluavtaws quartz muaju, amorphous silica, thiab vitreous silica. Qhov kev faib tawm no tsis ua tiav raws li muaj lwm daim ntawv ntawm silica tsim los rau kev siv tshwj xeeb.
