    Andalusite

    Andalusite yog ib qho aluminosilicate ntxhia, uas yog cov khoom siv los ua cov ntaub ntawv refractory thiab cov plooj (porcelain) hauv cov pob hluav taws xob.Nws yog ib qho ntxhia ntawm qib qis thermal metamorphism, thiab feem ntau pom nyob rau hauv av nkos nyob rau hauv kev sib cuag nrog metamorphic zones.Nws yog tsim nyob rau hauv cov kev mob ntawm high geothermal gradient thiab tsis tshua muaj siab mus rau qhov kub thiab txias piv.

    Andalusite feem ntau yog columnar siv lead ua, thiab nws hla ntu yog yuav luag square.Andalusite crystals sib sau ua ke rau hauv cov duab radial lossis granular.Tib neeg feem ntau hu cov radial andalusites "chrysanthemum pob zeb", uas txhais tau hais tias lawv zoo li cov paj ntawm chrysanthemum.

  • Sillimanite-Kyanit

    Sillimanite-Kyanit

    Cov siv lead ua ntawm kyanite yog cov kob silicate ntxhia ntawm triclinic system.Kyanite thiab andalusite, abscissas rau hauv homogenous ntau dua li.Cov muaju yog cov strips tiaj tus thiab qee zaum radial aggregates.Xiav, bluish dawb, cyan, hardness muaj pom tseeb txawv poj niam txiv neej.

  • Kaolin

    Kaolin

    Kaolin yog ib yam uas tsis yog-metallic ntxhia, yog ib hom av nplaum thiab av nplaum pob zeb dominated los ntawm kaolinite av nplaum ntxhia.
    Kaolin tau dhau los ua cov khoom siv ntxhia tsim nyog rau ntau qhov kev lag luam xws li papermaking, ceramics, roj hmab, tshuaj lom neeg kev lag luam, txheej, tshuaj thiab kev tiv thaiv hauv tebchaws.

  • Bauxite

    Bauxite

    Lub ntsiab tivthaiv ntawm bauxite yog alumina, uas yog hydrated alumina uas muaj impurities thiab yog ib yam ntawm cov ntxhia hauv av.Dawb los yog tawm-dawb, xim av daj los yog lub teeb liab vim muaj cov ntsiab lus hlau.Qhov ceev 3.45g / cm3, hardness 1 ~ 3, opaque thiab nkig.Yooj yim heev rau yaj.Insoluble hauv dej, soluble hauv sulfuric acid thiab sodium hydroxide tov.Feem ntau yog siv rau smelting aluminium thiab ua cov ntaub ntawv refractory.
    Cov muaj pes tsawg leeg ntawm bauxite yog heev complex, thiab nws yog ib tug dav lub sij hawm rau ntau yam ntawm hydrous alumina ore nrog txawv heev geological qhov chaw.Xws li boehmite, diaspore thiab gibbsite (Al2O3·3H2O);qee qhov muaj diaspore thiab kaolinite (2SiO2·Al2O3·2H2O);Qee qhov feem ntau yog tsim los ntawm kaolinite thiab ua raws li Cov ntsiab lus ntawm kaolinite yog cov bauxite lossis kaolinite av nplaum.Bauxite feem ntau yog tsim los ntawm cov tshuaj tiv thaiv huab cua lossis cov teebmeem exogenous.Muaj ob peb cov zaub mov ntshiab, thiab ib txwm muaj qee cov zaub mov tsis huv, ntau dua lossis tsawg dua cov av nplaum, cov zaub mov hlau, cov zaub mov titanium thiab detrital hnyav minerals.

  • Chamotte

    Chamotte

    Chamotte yog cov av nplaum zoo heev uas tsim tawm hauv Zibo, xeev Shandong, Suav.Tus qauv Al2O3 cov ntsiab lus ntawm chamotte ore yog 38%, tom qab calcination cov ntsiab lus Al2O3 yog li ntawm 44%, thiab Fe2O3 <2%.Cov muaj pes tsawg leeg yog ruaj khov, kev ntxhib los mos yog uniform, cov qauv yog ntom, thiab seem yog plhaub-puab thiab dawb.Nws yog siv los tsim cov ntaub ntawv zoo av nplaum refractory.Lub sij hawm kev kawm yog thawj qib nyuaj av nplaum clinker, cov tshuaj lom neeg tseem ceeb yog AL2O3 thiab SiO2, nrog rau me me ntawm Fe2O3 thiab cov lej ntawm Na2O thiab K2O.Lub ntsiab ntxhia yog kaolin.

    Lub chamotte peb hu feem ntau xa mus rau CALCINED CLAY..Cov ntsiab lus ntawm Al2O3 nyob rau hauv calcined chamotte yog hais txog 44%, thiab cov ntsiab lus ntawm Fe2O3 tsis ntau tshaj 2%.Cov muaj pes tsawg leeg yog ruaj khov, kev ntxhib los mos yog uniform, cov qauv yog ntom, thiab seem yog plhaub-puab.

    Cov xim ntawm chamotte tom qab kub kub calcination yog: dawb huv, lub teeb grey, lub teeb daj xim av, thiab ib qho me me ntawm cov ntawv hlau xim av.

  • Calcium carbide

    Calcium carbide

    Calcium carbide yog ib qho inorganic compound, dawb crystals, cov khoom lag luam yog grey-dub lumps, thiab hla ntu yog ntshav lossis grey.Nws reacts hnyav thaum ntsib dej, tsim acetylene thiab tso cua sov.Calcium carbide yog ib qho tseem ceeb ntawm cov tshuaj raw khoom, feem ntau yog siv los tsim cov roj acetylene.Kuj tseem siv rau hauv cov organic synthesis, oxyacetylene welding, thiab lwm yam. Lub cev thiab cov khoom siv tshuaj lom neeg: Cov ore yog daj-xim av los yog dub blocky khoom, thiab cov khoom ntshiab yog dawb crystalline (ib qho uas siab dua CaC2 yog ntshav).Nws muaj qhov ntom ntom ntawm 2.22 g / cm3 thiab lub ntsiab lus melting ntawm 2300 ° C (txog rau cov ntsiab lus ntawm CaC2).Nws tam sim ntawd tawm tsam hnyav thaum nws ntsib dej los tsim acetylene thiab tso cua sov.Lub melting point hloov nrog cov ntsiab lus calcium carbide sib txawv.
