Txij li thaum xyoo 1970s, cov khoom siv dag zog tau tsim muaj ntau, qhov tseem ceeb tshaj plaws yog silicon carbide thiab alumina. Silicon carbide feem ntau hu ua carborundum. Nws yog npaj los ntawm kev sib xyaw cov xuab zeb dawb huv thiab coke nrog me me ntawm cov ntoo chips, muab tso rau hauv lub qhov cub hluav taws xob, thiab ci ntawm 2, 200-2,480 degree rau li 36 teev. Alumina, feem ntau hu ua corundum, feem ntau yog siv rau hauv kev lag luam kom sov thiab yaj bauxite nyob rau hauv hluav taws xob arc rauv.
Cov xim dawb thiab pob tshab yog siv los ua cov khoom siv rau cov hlau kub-rhiab, thiab cov xim dub yog siv los ua cov castings thiab hlau. Synthetic pob zeb diamond sib tsoo log yog qhov nyuaj tshaj plaws abrasive cuab yeej, tsim nyog rau sharpening ntawm cemented carbide cov cuab yeej. Synthetic diamonds kuj tuaj yeem ua rau hauv cov cuab yeej ntawm ntau yam duab thiab ntau thiab tsawg, uas yog tsim rau txiav iav thiab ceramics. Lub hardness ntawm boron carbide yog siab dua li ntawm silicon carbide, yog li nws tsis haum rau kev sib tsoo log. Nws tuaj yeem siv los hloov pob zeb diamond kim thaum polishing cov ntaub ntawv nyuaj. Lub hardness ntawm cubic boron carbide yog ob zaug ntawm silicon carbide thiab 2.5 npaug ntawm alumina. Nws zoo heev rau kev sib tsoo qee yam cuab yeej steels.
