Lehlabathe la Quartz
Lehlabathe la quartz ke thepa ea tlhaho ea liminerale e entsoeng ka silicon dioxide (SiO₂), e hlahisoang ka ho pshatla, ho hlahloba le ho sebetsa lejoe la quartz. Ka lebaka la boima ba eona bo phahameng, botsitso ba lik'hemik'hale, le ho hanyetsa mocheso, e sebelisoa haholo libakeng tse fapaneng tsa indasteri.

Molemo oa tlhōlisano
Khampani e entse tlhahlobo ea melemo ea tlholisano ho tseba matla le mefokolo ea eona ha e bapisoa le bahlolisani ba eona.
Matla a Phahameng:
Mohs thata ea 7, e nang le khanyetso e matla ea ho apara.
01
Boiketlo ba Lik'hemik'hale:
E hanyetsana le asiti (ntle le hydrofluoric acid) le kutu, e sebetsa hanyane ka lik'hemik'hale tse ngata.
02
Kabelo e phahameng ea 'maraka
Ho Thibela Mocheso: Sebaka se qhibidihang hoo e ka bang ka 1750℃, se loketse maemo a phahameng a mocheso-.
03
Mokhoa o phethahetseng oa sehlahisoa
Insulation: Thepa e ntle haholo ea ho kenya motlakase.
04
E sebetsa hantle ka mora-litšebeletso tsa thekiso
Mmala & Foromo: Ka tloaelo li-granules tse pepenene tse tšoeu kapa tse se nang 'mala; e ka bonahala e le mosehla, e khubelu, joalo-joalo, ha litšila li le teng.
