Cov Lus Qhia Yooj Yim

Alumina ceramics yog ib qho ntawm feem ntau siv tau siv thiab thev naus laus zis ua rau lawv lub siab kub heev, hnav tsis kam, thiab tus nqi siab {1} {{1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} {1} - ua hauj lwm zoo. Alumina cov phiaj ceramina tau ua los ntawm alumina raws li cov khoom siv thawj, nrog cov khoom siv tsawg li fluxes, thiab yog sintered ntawm 1700 degree. Kev tsim qauv feem ntau koom nrog, sib sau, sintering, xov, sib tsoo, kev sib tsoo, thiab ntim. Cov txheej txheem tsim kev sib txawv raws li cov khoom lag luam, tab sis feem ntau categorized raws li qhuav nias lossis oreostatic nias. Nrog kev cog lus thev naus laus zis (xws li ua kom tawv thiab ua kom zoo dua thiab cov kev ua tau zoo thiab cov ntawv thov ntau yog txuas ntxiv.

Chipnano Advanced Cov Khoom Siv Alumina Cov Khoom Siv Tej Yam Ceramina, pas nrig, daim hlau, cov hlau, cov crucibles, cov kab ke, thiab lwm yam.

Cov yam ntxwv tseem ceeb ntawm Alumina Ceramics

Siab hardness thiab hnav tsis kam

Nws lub hardness yog ob tsuas yog rau ob peb cov ntaub ntawv, xws li pob zeb diamond, cubic boron nitride, thiab deb tshaj ntawm cov hlau thiab yas. Nws cov kev ua tau zoo heev ua rau nws tsim nyog tshwj xeeb rau cov ntawv thov raug hnav kom loj.

High Txhua Yam Zog

Nws lub zog compressive yog heev. Nws lub zog flexural kuj tseem muaj ntau (tshwj xeeb tshaj yog rau high- Kev pham swm dawb), tab sis nws cuam tshuam lub zog thiab tawv kuj tseem ceeb (raws li nws yog cov khoom siv loj me).

Siab - kub tsis kam

Nws melting point yog siab npaum li 2050 degree. Nws muaj cov kev kho tshuab zoo heev thiab tshuaj lom neeg stability txawm tias muaj kev kub siab (feem ntau txog 1600℃lossis siab dua, nyob ntawm kev coj dawb huv). Nws cov coefficient ntawm thermal expansion yog qhov tsawg.

Kev Rwb Zog Hluav Taws Xob Rwb Thaiv Tsev

Nws kub heev resistivity nyob rau hauv chav tsev kub ua rau nws cov khoom siv insulating zoo heev. Txawm tias thaum kub siab (piv txwv li, 1000 degree), nws tswj hwm cov khoom zoo insulating zoo. Nws dielectric poob yog tsawg . 5. Cov tshuaj ruaj khov: nws yog cov hlau roj acid, thiab muaj cov alkalis muaj zog). Nws tseem ua pov thawj zoo oxidation tiv thaiv.

Tsawg ntom ntom

Nrog qhov ntom ntom ntawm kwv yees li 3.6-3.9 g / cm³, nws yog qhov cuam tshuam ntau dua li cov hlau (piv txwv li, kwv yees li 7.M³).
