Alumina ceramic wafer 4 nti purity 99% polycrystalline hnav resistant 1 hli thickness

Lus piav qhia luv luv:

Aluminium oxide ceramic wafer yog cov ntaub ntawv raws li cov khoom siv hluav taws xob ceramic, uas tsim lub hauv paus kev txhawb nqa rau cov khoom siv hluav taws xob thiab cov khoom siv peripheral. Ceramic substrate muaj qhov zoo ntawm qhov kub thiab txias tsis kam, siab hluav taws xob rwb thaiv tsev kev ua tau zoo, tsis tshua muaj hluav taws xob tsis tu ncua thiab dielectric poob, thermal conductivity loj, kev ruaj ntseg tshuaj zoo, thiab cov thermal expansion coefficient zoo sib xws.

Product Detail

Khoom cim npe

Aluminium oxide (Al2O3) muaj kev sib xyaw ua ke ntawm cov khoom siv zoo heev thiab tus nqi qis tshaj. Lub zog txhua yam muaj zog, hardness, abrasion tsis kam, refractoriness, thermal conductivity, thiab chemical inertness tso cai rau kev hloov cov ntaub ntawv kim dua hauv qee kis los txo cov nqi tsim khoom. Cov ntsiab lus Al2O3 txawv ntawm 96% mus rau 99.7% thiab cov thickness txawv ntawm 0.25 hli. Qhov saum npoo tuaj yeem yog av lossis polished, metallized thiab hauv txhua qhov geometry.

Alumina ceramics muaj ntau yam kev siv hauv kev lag luam, cov hauv qab no yog qee qhov kev lag luam loj:

Abrasives thiab sib tsoo xov xwm: Alumina ceramics feem ntau yog siv los ua abrasives thiab sib tsoo xov xwm rau kev sib tsoo thiab polishing ntawm hlau, iav, ceramics thiab lwm yam ntaub ntawv vim lawv siab hardness thiab zoo hnav tsis kam.

Chemical reactor: Alumina ceramics tuaj yeem siv los ua cov khoom siv los yog ua rau hauv cov txheej txheem reactor, siv cov tshuaj reactors, tshwj xeeb tshaj yog nyob rau hauv kub kub, corrosive ib puag ncig.

Electronic ceramics: Alumina ceramics feem ntau siv rau hauv kev tsim cov khoom siv hluav taws xob, xws li insulators, capacitors, hluav taws xob ceramic substrates, thiab lwm yam, vim lawv cov khoom insulating thiab kub tsis kam.

Thermal kev lag luam: alumina ceramics feem ntau yog siv nyob rau hauv high-temperature furnaces thiab kilns, tshav kub rwb thaiv tsev, thermal rwb thaiv tsev thiab refractory ntaub ntawv rau thermal industrial khoom vim nws kub tsis kam thiab kub conduction zog.

Cov khoom siv kho mob: alumina ceramics kuj tseem siv rau hauv cov khoom siv kho mob, xws li cov pob qij txha, cov khoom siv kho hniav.
