Kapangidwe ka mankhwala a mikanda yoyandama makamaka ndi silicon dioxide ndi aluminiyamu oxide. Ili ndi makhalidwe ambiri monga tinthu tating'onoting'ono, topanda kanthu, topepuka, mphamvu zambiri, kukana kuwonongeka, kukana kutentha kwambiri, kutchinjiriza kutentha komanso kuletsa moto. Imagwiritsidwa ntchito kwambiri mu Chimodzi mwa zipangizo zopangira zinthu zotsutsana ndi moto.
