Zirconia Mortar thiab Pestle Description
Zirconia yog cov khoom siv lead ua dawb uas muaj xim dawb, tab sis tuaj yeem tsim cov xim sib txawv los siv los ua lwm lub pov haum rau pob zeb diamond lossis ua cov hniav nyiaj hniav kub ceramic hauv kev siv kho mob. Lawm, nws tshwm sim raws li lub translucent (tej zaum pob tshab) ntxhia baddeleyite, ib tug tsawg mineral uas muaj ib tug monoclinic prismatic siv lead ua qauv; xws li ib tug ntxhia muaj tsis sib npaug vectors. Kuj hu ua "ceramic steel", qhov no oxide ntawm zirconium yog tshuaj inert thiab raug suav hais tias yog ib qho ntawm cov khoom siv kho kom zoo nkauj, vim nws cov khoom zoo heev.
Tawm ntawm tag nrho cov khoom siv ceramic, zirconia muaj qhov siab tshaj plaws toughness thiab lub zog ntawm chav tsev kub. Ntawm qhov kub thiab txias, zirconia tuaj yeem dhau los ntawm kev hloov pauv loj hauv ntim thaum lub sijhawm hloov pauv. Yog li ntawd, nws yog ib qho nyuaj kom tau txais cov khoom ruaj khov zirconia thaum lub sij hawm sintering, uas yog vim li cas stabilization ntawm zirconia feem ntau yuav tsum tau. Stabilized zirconia ntxiv rau cov khoom siv tshwj xeeb thiab cov tshuaj inertness ib theem siab ntawm cov tshuaj stability, txawm nyob rau hauv ib puag ncig hnyav. Cov ntaub ntawv ntsig txog suav nrog yttria-stabilized zirconia (YSZ), calcia-stabilized zirconia (CSZ), magnesia-stabilized zirconia (MSZ), thiab lwm yam.
Zirconia lub siab ceev, tsis tshua muaj porosity, inertness, toughness, thiab super hardness ua rau nws cov khoom zoo meej rau kev ua mortars thiab pestles. Ua li ntawm 10 ntawm Mohs hardness scale, zirconia mortar thiab pestles muaj peev xwm zom cov ntaub ntawv uas nyuaj heev rau agate, alumina, los yog porcelain. Peb lub siab hnav-resistant mortar thiab pestle zoo tshem tawm cov khoom sib kis thiab yog tshuaj lom neeg rau cov kua qaub thiab alkalis.

Zirconia mortar thiab pestle daim ntaub ntawv thiab lwm yam lag luam
● Cov khoom siv tawv
Zirconia superior hardness tso cai rau nws mus zom tawv ceramics xws li txhuas oxide thiab silicon oxide
● Cov ntaub ntawv muaj paug tsawg
Thaum tsis muaj kev sib kis kiag li, xws li hauv cov organic ultra-ntshiab, nanomaterial, thiab forensic daim ntaub ntawv, Zirconia yog qhov zoo tshaj plaws xaiv.
● HF Daim Ntawv Thov
Zirconia lub inertness rau HF thiab lwm yam acids ua rau nws superior rau Agate thiab lwm yam ntaub ntawv
● Kev siv kub-kub
Zirconia lub cev thiab thermal poob siab kuj qiv nws zoo rau cov ntawv thov kub
