Hmoov Wollastonite, cov khoom siv inorganic ua tau zoo, tau nce qib hauv kev lag luam thoob ntiaj teb rau nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb. Muab los ntawm cov calcium metasilicate ntuj (CaSiO₃) cov pob zeb, tus neeg sawv cev no muaj ntau yam khoom siv thiab cov khoom siv txhawb nqa muab cov txiaj ntsig zoo tshaj plaws hauv cov khoom siv ceramics, plastics, coatings, kev tsim kho, thiab kev siv tsheb.

Raws li cov qauv, wollastonite yog cov pob zeb silicate uas yog ib feem ntawm pawg pyroxenoid, uas crystallizes hauv lub triclinic system. Nws cov yam ntxwv tshwj xeeb tshaj plaws yog nws cov qauv zoo li koob/fibrous, nrog rau cov piv ntawm cov yam ntxwv feem ntau yog txij li 8: 1 txog 30: 1, thiab cov qib siab tshaj plaws txog li 50: 1. Cov qauv acicular no tsim los ntawm cov saw hlau tsis kawg ntawm [SiO2].₄] tetrahedra txuas nrog los ntawm calcium ions. Cov pob zeb zoo li dawb mus rau dawb tawm, nrog Mohs hardness ntawm 4.5–5.5, qhov ceev ntawm 2.75–2.9 g/cm3³, thiab lub ntsiab lus yaj ntawm 1540°C. Nws muaj kev ruaj khov tshuaj zoo heev, kev nqus roj tsawg, kev khaws cia dej tsawg, kev nthuav dav thermal tsawg, thiab kev dawb siab.

Hauv kev siv hauv kev lag luam, wollastonite cov qauv zoo li koob muab cov txiaj ntsig zoo kawg nkaus. Hauv cov khoom siv ceramics, nws txo qhov kub tua hluav taws los ntawm 50–100°C, ua kom luv luv lub voj voog tua hluav taws, txhim kho lub zog, tiv thaiv kev tawg, thiab txhim kho qhov du ntawm cov xim ci. Hauv cov yas thiab roj hmab, nws ua rau lub zog tensile, rigidity, thiab dimensional stability ntau dua thaum txo cov nqi khoom siv. Kev lag luam coatings siv nws los txhim kho kev ruaj khov, kev tiv thaiv corrosion, thiab kev npog, txo kev vam khom rau titanium dioxide.

Nws ua haujlwm ua ib qho asbestos hloov pauv uas tsis ua rau ib puag ncig puas tsuaj hauv cov khoom sib txhuam (nres nres, clutch facings) thiab cov ntaub ntawv tiv taus hluav taws. Hauv kev tsim kho, nws ua rau lub zog ntawm cov pob zeb ua kom muaj zog thiab tiv taus hluav taws thaum txo cov pa roj carbon. Kev lag luam ntawv tau txais txiaj ntsig los ntawm nws lub peev xwm los ua kom muaj qhov tsis pom tseeb, du, thiab luam tawm tau. Nws kuj pom tias siv hauv metallurgy ua cov slag tiv thaiv thiab hauv kev ua liaj ua teb ua cov av pH adjuster.

Thaum cov chaw tsim khoom nrhiav cov khoom siv ruaj khov thiab ua tau zoo, hmoov wollastonite txuas ntxiv nthuav nws txoj kev lag luam. Nws cov txiaj ntsig zoo ntawm cov qauv tsim ua rau nws yog cov khoom siv tseem ceeb rau kev txhim kho kev lag luam niaj hnub.
