Superfine alumina yog ib qho tseem ceeb raw khoom rau kev ua haujlwm ceramics. Superfine alumina hmoov xz-L20, particle loj 100 nm, xim dawb, 99% ntawm cov ntsiab lus khoom. Nws tuaj yeem muab ntxiv rau ntau yam dej-raws li cov resins, hauv cov roj-raws li resins, cov kuab tshuaj thiab cov roj hmab ntawm qhov sib ntxiv ntawm 3% -5%, uas tuaj yeem txhim kho cov tawv tawv ntawm cov khoom mus txog 6-8H lossis siab dua.
Grain Q-A1203, nrog nws cov tshuaj lom neeg tsawg thiab kub tsis kam, tsis yog alumina qhuav, thiab tsis muaj kev ua haujlwm catalytic. Nws muaj zog tiv thaiv tshav kub, zoo formability, ruaj khov crystalline theem, siab hardness thiab zoo seem stability, thiab yuav tau lug siv nyob rau hauv lub reinforcement thiab toughening ntawm ntau yam plastics, roj hmab, ceramics, refractory cov ntaub ntawv thiab lwm yam khoom, tshwj xeeb tshaj yog los txhim kho qhov ntom ntom, tiav, kub thiab txias qaug zog, tawg toughness, creep kuj ntawm ceramics thiab hnav tsis kam ntawm polymer cov ntaub ntawv.
