Polycrystalline Al2O3 alumina ceramics customized kub siab hnav tsis kam

Kev ua tau zoo ntawm txhuas oxide ceramics

1--Qhov nyuaj siab

Rockwell hardness ntawm alumina ceramics yog HRA80-90, thib ob tsuas yog pob zeb diamond hauv qhov nyuaj, ntau dua li cov hlau hnav-resistant thiab stainless hlau hnav-resistant.

2 - Kev Tiv Thaiv Zoo

Qhov kev tiv thaiv kev hnav ntawm alumina ceramics yog sib npaug rau 266 zaug ntawm manganese hlau thiab 171.5 zaug ntawm cov hlau chromium siab. Nyob rau hauv tib lub sijhawm ua haujlwm, nws tuaj yeem ntev lub neej ntawm cov khoom siv tsawg kawg yog kaum zaug.

3--Lub teeb yuag

Qhov ceev ntawm alumina ceramics yog 3.7 ~ 3.95g / cm °, uas tsuas yog ib nrab ntawm cov hlau thiab hlau, thiab tuaj yeem txo qhov hnyav ntawm cov khoom siv.

4--Ntau yam ntawm daim ntawv thov

Alumina ceramics yog siv dav hauv tshuab, fiber optics, cov cuab yeej txiav, kev kho mob, khoom noj, tshuaj lom neeg, aerospace thiab lwm yam teb.

Qhov zoo ntawm alumina ceramics:

1--Alumina ceramics muaj cov khoom rwb thaiv tsev zoo heev. Kev poob ntawm zaus siab yog qhov me me, thiab kev rwb thaiv tsev zaus siab yog qhov zoo.

2 - Alumina ceramics muaj kev tiv thaiv cua sov, coefficient me me ntawm thermal expansion, lub zog siab thiab thermal conductivity zoo.

3 - Alumina ceramics muaj kev tiv thaiv tshuaj lom neeg thiab kev tiv thaiv hlau molten.

4 - Alumina ceramics tsis yooj yim hlawv, tsis yooj yim xeb thiab muaj zog thiab tsis yooj yim puas tsuaj, nrog rau lwm cov ntaub ntawv organic thiab cov ntaub ntawv hlau tsis tuaj yeem piv rau qhov zoo heev.

5--Alumina ceramics zoo heev hnav tsis kam, qhov nyuaj thiab corundum zoo ib yam, tuaj yeem ncav cuag Mohs hardness 9, nws qhov hnav tsis kam tuaj yeem phim nrog cov hlau nplaum super-hard.
