Kusiyana pakati pa mchenga wa quartz, mchenga wa silika ndi silika

Mchenga wa quartz ndi mchenga wa silika umapangidwa makamaka ndi silicon dioxide. Iwo amasiyanitsidwa potengera zomwe zili silika. Silika zomwe zili pamwamba pa 98.5% zimatchedwa mchenga wa quartz, ndipo silicon dioxide pansi pa 98.5% imatchedwa mchenga wa quartz. Silika, chilinganizo cha mankhwala ndi sio2. Pali mitundu iwiri ya silika m’chilengedwe: Du crystalline silica ndi amorphous Zhi silica. Chifukwa cha kusiyana kwa kapangidwe ka chilumba cha crystalline, silika wa crystalline akhoza kugawidwa m’magulu atatu: quartz, tridymite ndi cristobalite. Silika amagwiritsidwa ntchito popanga magalasi athyathyathya, zinthu zamagalasi, mchenga woyambira, ulusi wagalasi, glaze yamtundu wa ceramic, anti- dzimbiri sandblasting, mchenga wosefera, flux, zida zokanira ndi thovu lopepuka konkire.

Mchenga wa quartz ndi tinthu tating’ono ta quartz tomwe timasweka kukhala mwala woyera wa quartz. Quartzite ndi mchere wopanda zitsulo. Ndi mchere wolimba, wosavala komanso wosasunthika wa silicate. Chigawo chachikulu cha mchere ndi silika. Mchenga wa Quartz ndi woyera wamkaka kapena wopanda mtundu komanso wowoneka bwino. Kuuma kwake ndi 7. Mchenga wa quartz ndi chinthu chofunika kwambiri cha mafakitale opangira mchere, zinthu zopanda mankhwala zowopsa, zomwe zimagwiritsidwa ntchito kwambiri mu galasi, kuponyera, zoumba ndi zipangizo zowonongeka, kusungunula ferrosilicon, flux metallurgical, zitsulo, zomangamanga, makampani opanga mankhwala, mapulasitiki, mphira, abrasives, zosefera ndi mafakitale ena.

Quartz mumchenga wa silika ndiye gawo lalikulu la mchere komanso kukula kwa tinthu. Malinga ndi njira zosiyanasiyana zamigodi ndi kukonza, 0.020mm-3.350mm refractory particles akhoza kugawidwa mu yokumba silika mchenga ndi masoka silika mchenga, monga osambitsidwa mchenga, osambitsidwa mchenga ndi kusankha (flotation) mchenga. Mchenga wa silika ndi mchere wolimba, wosavala komanso wosasunthika wa silicate. Chigawo chake chachikulu cha mchere ndi silicon dioxide. Mchenga wa silika ndi woyera wamkaka kapena wopanda mtundu komanso wowoneka bwino.
