Thaum Lub Yim Hli 14, 2021, tus neeg sau xov xwm los ntawm Xinhua News Agency tau tsim cov khoom siv amorphous tshiab (AM-III) los ntawm ib lub xeev lub chaw soj ntsuam tseem ceeb, Yanshan University Semi-Stable Materials Preparation Science thiab Technology Institute.Kawm paub tias kuv ua tiav li cas...Amorphous cov ntaub ntawv, tseem hu ua cov ntaub ntawv vitreous, yog cov khoom loj loj.iav, uas feem ntau siv hauv tib neeg lub neej, yog cov khoom siv amorphous.
Raws li cov kws tshaj lij, qhov ceev ntawm AM-III yog piv rau cov pob zeb diamond.thiab Vickers HV hardness txog li 113 GPa muaj peev xwm rhuav tshem cov pob zeb diamond ib leeg.Yog li, nws yog qhov nyuaj tshaj plaws thiab muaj zog tshaj amorphous khoom puas tau pom.
Nws yog tsim nyog sau cia tias:
Pob zeb diamond yog cov ntxhia nyuaj tshaj plaws hauv qhov xwm txheej.Nws muaj Mohs hardness 10 raws li Mohs hardness nplai.Qhov sib txawv loj tshaj plaws ntawm qib 9 thiab qib 10, qib 10 pob zeb diamond hardness yog 150 npaug ntawm qib 9 corundum, nws yog 1000 npaug ntawm hardness.Qib 7 quartz.
Lub hardness ntawm pob zeb diamond yog siab heev.Tab sis lub hardness ntawm pob zeb diamond yog anisotropic thiab txawv nyob ntawm seb cov kev taw qhia.nyob rau hauv lwm yam lus Lub hardness ntawm txhua nto yog txawv.Thiab qhov hardness 001 yuav tsis siab tshaj.
