Talc yog qhov softest thiab pob zeb diamond yog qhov nyuaj tshaj. Txhua lub pob zeb tuaj yeem khawb tsuas yog cov hauv qab nws ntawm qhov ntsuas.
Qhov twg yog cov khoom softest?
Raws li Mohs nplai, talc, tseem hu ua soapstone, yog cov ntxhia pob zeb zoo tshaj plaws; nws yog tsim los ntawm ib pawg ntawm cov ntaub ntawv tsis muaj zog txuas nrog uas zoo li plam sib nrug nyob rau hauv siab. Thaum nws los txog rau cov hlau, cov kws tshawb fawb sim ntsuas qhov nyuaj ntawm cov ntsiab lus tseeb.
Dab tsi yog ob qho dej ntxhia tshaj plaws?
Txhua qhov kev xav tau cov zaub mov haum hauv qhov ntsuas no, txij li Talc yog cov pob zeb uas paub zoo tshaj plaws thiab pob zeb diamond nyuaj tshaj plaws.
Lub 10 minerals yog:
- Talc.
- Gypsum.
- calcite.
- Fluorite.
- Apatite.
- Feldspar.
- Quartz.
- YTopaz.
Vim li cas talc soft?
Lub softness ntawm talc tau txais txiaj ntsig rau nws lub cev thiab tshuaj lom neeg. Talc yog tsim los ntawm cov qauv ntawv nrog cov ntawv cog lus zoo meej cleavages thiab tsis muaj zog heev ntawm cov nplooj ntawv. Vim cov qauv zoo li no, cov ntawv talc tuaj yeem yooj yim plam ntawm ib leeg. Cov yam ntxwv ntawm talc no ua rau nws softness.
pob zeb softest yog dab tsi?
Talc yog cov ntxhia mos tshaj plaws hauv ntiaj teb. Mohs scale ntawm hardness siv talc raws li nws pib-point, nrog ib tug nqi ntawm 1. Talc yog ib tug silicate (zoo li ntau yam ntawm lub ntiaj teb no cov minerals ntau tshaj), thiab ntxiv rau silicon thiab oxygen,muaj magnesium thiab dej npaj rau hauv cov ntawv hauv nws cov qauv siv lead ua.
