Qhov zoo

1. Kev nyuaj siab thiab hnav tsis kam Hardness:

Qhov Mohs hardness ntawm alumina ceramics yog siab txog qib 9, thib ob tsuas yog pob zeb diamond. Kev hnav tsis kam: Nws qhov kev hnav tsis kam yog 266 npaug ntawm cov hlau manganese thiab 171.5 npaug ntawm cov hlau chromium siab.

2. Kev kub siab thiab kev ruaj khov thermal

Kev ua haujlwm kub siab: Lub ntsiab lus yaj ntawm alumina ceramics yog siab txog 2050 ℃, thiab nws tuaj yeem tswj tau qhov ua tau zoo ntawm qhov kub siab ntawm 2000 ℃. Kev ruaj khov thermal: Nws muaj cov coefficient qis ntawm kev nthuav dav thermal thiab tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv hauv qab qhov kub hloov pauv hnyav.

3. Tsim qauv sib dua

Qhov ceev ntawm alumina ceramics tsuas yog 3.6-3.8g / cm ³, uas yog ntau tshaj 50% sib dua li hlau. Piv txwv li, kev siv cov khoom alumina ceramic hauv dav hlau tuaj yeem txo qhov hnyav los ntawm 30% thiab txhim kho kev siv roj ntau.

4Kev tiv thaiv xeb thiab cov khoom rwb thaiv tsev Kev tiv thaiv xeb:

Kev tiv taus zoo heev rau cov kua qaub muaj zog, alkalis, thiab ntsev nruab nrab, tsim nyog rau cov tshuaj reactors, cov li qub tiv thaiv xeb, thiab lwm yam. Kev rwb thaiv tsev: Nrog rau qhov tsis kam ntawm ≥ 1 × 10 ¹⁴Ω· cm, nws yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob siab.

5. Kev siv nyiaj tsim nyog Kev siv nyiaj tsim nyog:

Nws lub neej ntev thiab cov yam ntxwv tsis tas yuav saib xyuas ntau ua rau cov nqi siv mus sij hawm ntev txo qis.

6. Kev ua tiav tshwj xeeb Precision machining:

Los ntawm cov txheej txheem xws li kev nias qhuav, kev txhaj tshuaj molding, thiab 3D luam ntawv, cov khoom sib xyaw ua ke tuaj yeem ua kom tau raws li qhov xav tau ntawm cov teb siab xws li semiconductors thiab cov khoom siv kho mob. Kev hloov kho sai: Cov lag luam tuaj yeem hloov kho cov khoom siv ceramic raws li cov khoom siv, txo cov nqi hloov kho.

7. Kev Tiv Thaiv Ib Puag Ncig thiab Kev Ruaj Khov Kev tsim cov pa roj carbon tsawg:

Cov khoom siv raw rau alumina ceramics (alumina hmoov) muaj ntau yam, thiab kev siv zog ntawm cov txheej txheem sintering qis dua li ntawm cov hlau smelting. Kev Rov Siv Dua: Cov khoom siv ceramics pov tseg tuaj yeem raug tsoo thiab rov ua dua tshiab ua cov khoom siv raw kom tsis txhob muaj kev pheej hmoo ntawm kev ua qias tuaj los ntawm cov khoom siv hlau pov tseg.
