Zirconia Block yog dab tsi?

Raws li peb txhua tus paub muaj peb hom khoom siv rau kev kho hniav: zirconia thaiv cov khoom thiab cov khoom siv hlau.Zirconium oxide tshwm sim raws li monoclinic, tetragonal thiab cubic siv lead ua cov ntaub ntawv.Densely sintered qhov chaw tuaj yeem tsim ua cubic thiab / lossis tetragonal siv lead ua cov ntaub ntawv.Txhawm rau kom ruaj khov cov qauv siv lead ua no, stabilizers xws li magnesium oxide (MgO) lossis yttrium oxide (Y2O3) yuav tsum tau ntxiv rau ZrO2.

Vim li cas zirconia thaiv yog cov khoom tsim nyog tshaj plaws hauv kev kho hniavkev kho dua tshiab?

Cia peb tham txog kev tsim zirconia.Cov hniav zirconia thaiv yog ua los ntawm crystalline oxide daim ntawv ntawm zirconium, thiab nws muaj ib tug hlau atom nyob rau hauv lub siv lead ua tab sis yeej tsis suav hais tias yog hlau.Vim nws cov khoom ruaj khov thiab biocompatible, cov kws phais lossis kws kho mob siv cov hniav zirconia thaiv nyob rau hauv ntau yam prostheses.Txawm tias nws yog siv nyob rau hauv implants raws li nws yog suav hais tias yog cov khoom siv zog tshaj plaws.

Txawm hais tias muaj ntau yam khoom siv hauv kev lag luam kho hniav, cov hniav zirconia block kuj hu ua ceramic block yog nto moo tshaj plaws ntawm cov kws kho hniav thiab cov neeg mob.

Qee qhov zoo rau cov hniav zirconia blocks:

- Raws li nws yog tsim los ntawm high-tech kev loj hlob.Nrog rau siab tawg toughness, thermal expansion zoo ib yam li cam khwb cia hlau, tsis tshua muaj siab dabtsi yog khoov lub zog thiab tensile zog, siab tsis kam mus hnav thiab corrosion, tsawg thermal conductivity

- Tsis tas li ntawd, nws tau pom zoo los ntawm cov koom haum hauv tebchaws.Tsis tas li ntawd, cov blocks no tau dhau los ua qee qhov kev sim purity, kom paub tseeb tias nws muaj kev nyab xeeb kiag li siv.

-Dental zirconia block yog cov khoom lag luam zoo, thiab nws kuj ua rau cov hniav ntau ruaj thiab ntuj.

-Thaum cov khoom cog rau hauv tus neeg mob, nws yuav muab lub neej txee zoo rau cov khoom.

-Lwm cov txiaj ntsig tseem ceeb ntawm qhov thaiv hniav zirconia yog nws yuav txo tau lub sij hawm ua ntej ziab thiab txhim kho qhov pom kev pom thaum lub sij hawm dyeing.

-Qhov tseem ceeb tshaj plaws ntawm cov khoom no yog nws tuaj yeem muaj cov xim ntuj rov tshwm sim, thiab nws kuj tuaj yeem phim txhua qhov loj thiab cov duab.
