Q Mocheso o phahameng ka ho fetisisa oa ts'ebetso oa khalase ea quartz e kopantsoeng ke ofe?

Khalase ea quartz e kopantsoeng e ka mamella mocheso oa tšebeliso ea nako e khuts'oane oa ho fihla ho 1300 °C le mocheso oa tšebeliso o tsoelang pele oa nako e telele oa ho fihla ho 1100 °C. Mocheso oa eona oa ts'ebetso ea mocheso o tloha ho 1750 °C ho isa ho 2050 °C, e leng se etsang hore e be e 'ngoe ea lisebelisoa tsa khalase tse tsitsitseng ka ho fetisisa tse fumanehang.

Q Ke hobane'ng ha khalase ea quartz e kopantsoeng e na le coefficient e tlase ea katoloso ea mocheso?

Koefficient e tlase haholo ea katoloso ea mocheso ea 5.5 × 10⁻⁷ cm/cm·°C ke phello ea sebopeho sa eona sa amorphous silicon dioxide (SiO₂). Thepa ena e fa quartz e kopantsoeng khanyetso e ikhethang ea mocheso, e e lumellang ho mamella liphetoho tse potlakileng tsa mocheso ntle le ho petsoha.

Q Sehlopha sa PPM se bolela'ng bakeng sa khalase ea quartz 'me ke hobane'ng ha se le bohlokoa?

Kereiti ya PPM (dikarolo ka milione) e bolela boemo ba ditshila tsa tshepe ka hara khalase ya quartz. E fumaneha ka dikereiti tse laolwang tsa 10, 20, le 100 PPM, boleng bo tlase ba PPM bo bontsha bohlweki bo hodimo, e leng sa bohlokwa bakeng sa ditshebediso tsa indasteri tsa semiconductor, optical, le tse nepahetseng haholo moo tshilafalo e lokelang ho fokotswa.

Q Matla a ho hatella a quartz e kopantsoeng a bapisoa joang le matla a eona a ho kokobela?

Quartz e kopantsoeng e na le matla a phahameng haholo a ho hatella a 1100 MPa, e leng se etsang hore e hanele matla a khatello haholo. Leha ho le jwalo, matla a yona a ho kobeha (a kobehang) a tlase haholo ho 67 MPa, e leng ntho e tlwaelehileng bakeng sa thepa ya khalase.
