Khoom Description

Dawb tabular alumina yog ib qho ntshiab sintered alpha-alumina cov khoom uas tau ua kom tag nrho densified los ntawm sai - sintering yam tsis siv cov sintering pab ntawm kub tshaj 1900℃.White Tabular Alumina, uas yog hu ua tabular corundum, yog ib hom ntawm sintered. Nws yog sintered sai nyob rau hauv qhov kub thiab txias 1900 degree, uas yog me ntsis qis dua lub melting point ntawm Al2O3 (2050℃).Dawb tabular alumina muaj tus yam ntxwv loj, zoo tsim hexagonal ntsiav tshuaj zoo li alpha{10}}alumina muaju. Qhov zoo tshaj plaws thermal ntim ruaj khov thiab cov yam ntxwv thermal shock tuaj yeem raug ntaus nqi rau nws qhov tshwj xeeb microstructure: qis qhib porosity thiab cov muaju loj nrog kaw lub qhov pores, uas tau nkag mus rau re-crystallization thaum lub sij hawm sintering ceev.

Dawb tabular alumina nplej ua kom tiav sintered recrystallized -Al2O3, qhia ob-dimensional planar tabular zoo thiab ntau integranular thiab intracrystalline ncig kaw qhov pores microstructure yam ntxwv.Ground Tabular yog ib yam khoom zoo heev los siv los ua ib qho muab tub lim hauv epoxy lossis resin tshuab qhov kev ua tau zoo ntawm lub zog dielectric zog. khoom zoo thiab daim ntawv thov kev ua tau zoo ntawm tabular corundum, nws yog tshwj xeeb uas nruab nrog ib tug zoo meej thiab siab heev tsom xam system thiab zoo tswj system kom ua tiav tag nrho cov kev soj ntsuam ntawm cov txheej txheem ntsuas thiab tag nrho cov kev tswj ntawm cov khoom zoo.

Khoom Zoo

1. High hardness: Lub hardness ntawm dawb corundum yog siab heev. Nws hardness yog thib ob tsuas yog pob zeb diamond, nrog lub hardness ntawm tshaj 9.0. Yog li ntawd, dawb corundum muaj kev hnav zoo heev, siab zog, thiab tsis yooj yim puas los ntawm lwm yam.

2. Zoo kub tsis kam: Dawb corundum tsis tsuas yog muaj siab hardness, tab sis kuj muaj zoo heev kub kuj. Cov khoom siv dawb corundum tuaj yeem ua haujlwm ruaj khov hauv qhov chaw kub siab tshaj 1200 degree. Nws yuav tsis deform los yog tawg vim qhov kub thiab txias thiab yog heev haum rau siv nyob rau hauv high -kub furnaces, siab - kub kilns thiab lwm yam teb.

Zoo corrosion kuj: Dawb corundum muaj corrosion kuj zoo heev thiab tsis yooj yim eroded los ntawm cov tshuaj. Nws cov khoom siv tshuaj muaj zog heev, nrog rau cov tshuaj tiv thaiv antioxidant zoo thiab tshuaj lom neeg ruaj khov, thiab nws tuaj yeem ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw huab cua xws li acids thiab alkalis.

4. Uniform particle loj thiab zoo crystallinity: lub particle loj ntawm cov khoom dawb corundum yog ib yam zoo thiab muaj crystallinity zoo. Cov khoom zoo no tiv thaiv cov khoom dawb corundum los ntawm muaj ntau cov burrs thiab pores, ua rau lawv qhov chaw du thiab muag heev. Qhov no tuaj yeem ua rau cov khoom siv dawb corundum muaj lub neej ntev thiab kev ua haujlwm ruaj khov.

5. Kev siv ntau yam: Dawb corundum muaj ntau yam kev siv. Nws tuaj yeem siv rau hauv siab- kub seals, hnav- cov khoom siv tiv taus, corrosion- cov khoom tiv taus, siab - cov ntaub ntawv kub kub refractory, ultra- zoo grinder qhov chaw thiab lwm yam teb. Vim tias dawb corundum muaj cov khoom zoo tshaj plaws hauv txhua yam, nws muaj txiaj ntsig zoo heev hauv kev ua haujlwm tiag tiag thiab yog qhov kev xaiv tseem ceeb raws li kev tsim khoom.
