Zirconia yog ib chav kawm tseem ceeb ntawm cov ntaub ntawv ceramic li cov ceramics siab heev, thiab yog cov khoom siv tseem ceeb heev rau kev txhim kho kev lag luam niaj hnub high-tech. Zirconia ceramics, nrog cov ntsiab lus siab melting thiab boiling point, siab hardness, zoo heev hnav tsis kam, raws li ib tug insulator ntawm chav tsev kub, thiab kub kub muaj zoo heev zog xws li hluav taws xob conductivity.Zirconia ceramics muaj kev koom tes nyob rau hauv ib tug ntau yam ntawm cov teb thiab nyob rau hauv feem ntau ntawm cov khoom. peb lub neej. Cov chaw pabcuam suav nrog: 5G kev sib txuas lus, petrochemical, khoom siv kho mob, kev lag luam photovoltaic, aerospace, khoom siv tub rog, semiconductors, khoom siv hluav taws xob, twj tso kua mis, lithium roj teeb, thiab lwm yam.
Cov khoom thiab cov yam ntxwv ntawm zirconia ceramics
Zirconia ceramics yog ib hom tshiab ntawm high-tech ceramics, nws ntxiv rau lub zog siab, hardness, kub tsis kam, acid thiab alkali corrosion kuj thiab siab tshuaj stability thiab lwm yam kev mob, tib lub sij hawm nrog khawb kuj thiab hnav tsis kam, tsis muaj teeb liab shielding, zoo heev tshav kub dissipation kev ua tau zoo thiab lwm yam ntxwv, thaum muaj zog machinability, zoo tsos nyhuv.
1, siab melting point, siab melting point thiab tshuaj inertness ua zirconia yuav siv tau raws li ib tug zoo refractory;
2, nrog ntau dua hardness thiab zoo hnav tsis kam;
3, lub zog thiab toughness kuj loj;
4, tsis tshua muaj thermal conductivity, tsawg expansion coefficient, haum rau cov khoom siv ceramic;
5, kev ua tau zoo ntawm hluav taws xob, los ntawm kev tiv thaiv kev ua haujlwm ntawm qhov pom, zirconia ceramic ua cov khoom tsis yog xim hlau tsis muaj kev tiv thaiv ntawm cov teeb liab electromagnetic, yuav tsis cuam tshuam rau lub kav hlau txais xov sab hauv.
