Yuav ua li cas kom paub qhov hardness ntawm dub silicon carbide?

Cov txheej txheem kev lag luam ntawm cov xim dub silicon carbide yog siv quartz xuab zeb thiab roj av coke hauv qhov cub ua kom zoo dua. Refined silicon carbide block, los ntawm crushing, acid-base ntxuav, sib nqus sib nqus thiab tshuaj ntsuam los yog dej sib cais thiab ua rau ntau yam khoom me me. Yog li yuav ua li cas thiaj paub qhov hardness ntawm dub silicon carbide?

Silicon carbide kuj tseem nyob nruab nrab ntawm corundum thiab pob zeb diamond, txhua yam muaj zog dua li corundum hnav-resistant khoom. Thiab muaj kev hnav zoo dua yog kev xaiv cov khoom siv abrasive. Sib tsoo log hnav-tiv thaiv los yog tsis, noj ceev thiab qeeb los ntawm kev sim yooj yim tuaj yeem tau txais cov ntaub ntawv raug ntau dua. Black silicon carbide hardness nrhiav kom tau txoj hauv kev yog raws li nram no: atomic absorption: Qhov kev kuaj xyuas no tuaj yeem kuaj xyuas cov ntsiab lus ntawm silicon, txiav txim siab qhov nyuaj ntawm cov xim dub silicon carbide, qhov kev kuaj xyuas tus nqi yog qhov tseeb. Kev ntsuas particle tsis kam: Kev ntsuas particle tsis kam yog siv los ntsuas qhov loj me ntawm cov xim dub silicon carbide, uas tuaj yeem txiav txim siab txiav cov xim dub silicon carbide, nrhiav kom pom kev ua haujlwm siab.
