Cov Khoom Tshwj Xeeb Ntawm Alumina Ceramics

Alumina ceramic yog cov khoom siv hluav taws xob zoo heev, uas tuaj yeem tiv taus cov tam sim no siab heev, thiab nws cov dielectric tsis tu ncua thiab ntim tsis kam nce nrog qhov nce ntawm purity ntawm alumina. Hauv kev lag luam, nws feem ntau siv rau insulators ntawm cov tshuab loj.

Alumina ceramic muaj lub siab melting point thiab txhua yam muaj zog, los ntawm kev sim, tsis muaj txhua yam load, alumina ceramic kub tuaj yeem ncav cuag 1650 degree. Txawm li cas los xij, thaum qhov kub siab tshaj 1000 ° C, lub zog txhua yam ntawm alumina ceramics yuav raug txo, vim qhov sib txawv loj hauv nws cov coefficient ntawm thermal expansion, thaum raug kub heev, nws thermal shock kuj tsis tshua muaj txiaj ntsig.

Alumina ceramics muaj tshuaj lom neeg ruaj khov thiab corrosion kuj. Nws yog feem ntau siv hauv kev lag luam tshuaj. Alumina kuj yog me ntsis soluble nyob rau hauv muaj zog acids (xws li kub sulfuric acid thiab kub HCl thiab HF kuj muaj ib tug tej yam corrosive nyhuv) thiab alkaline daws, insoluble nyob rau hauv dej. Ntshiab alumina yog resistant rau tshuaj corrosion, ua ntshiab alumina ceramic cov ntaub ntawv yog thawj xaiv rau engineering Cheebtsam nyob rau hauv ib tug ntau yam ntawm industrial daim ntaub ntawv. Nws cov tshuaj tiv thaiv corrosion tau pom tias yog vim nws cov solubility tsawg hauv cov tshuaj no.

Alumina ceramics muaj cov khoom zoo heev ntawm kev ua haujlwm siab, tsis tshua muaj siab thiab siab compressive zog. Cov yam ntxwv no tau coj mus rau nws daim ntawv thov nyob rau hauv cov tub rog riam phom. Xws li tank armor, lub cev armor thiab lwm yam.

Alumina ceramics muaj kev hnav zoo heev thiab feem ntau yog siv los ua cov tshuab chais, bearings, hnav-tiv taus linings, riam sharpens, precision qhov chaw nyob rau hauv high-wear ib puag ncig, thiab lwm yam. lwm.

Alumina ceramics muaj lom inertia thiab khoom noj khoom haus compatibility. Nws yog dav siv hauv kev kho mob kev lag luam thiab kev lag luam ua zaub mov.
