Maqephe a khalase a Quartz JGS1 JGS2 JGS3

Tlhaloso e Khutšoanyane:

Maqephe a khalase a Quartz, a tsejoang hape e le lipoleiti tsa silica tse kopantsoeng kapa lipoleiti tsa quartz, ke thepa e ikhethang haholo e entsoeng ka silicon dioxide e hloekileng haholo (SiO₂). Maqephe ana a bonaletsang le a tšoarellang a ananeloa ka lebaka la ho hlaka ha 'mele ho ikhethang, ho hanyetsa mocheso le botsitso ba lik'hemik'hale. Ka lebaka la thepa ea 'ona e phahameng, maqephe a khalase a quartz a sebelisoa haholo liindastering tse ngata, ho kenyeletsoa li-semiconductors, optics, photonics, matla a letsatsi, metallurgy le lits'ebetso tse tsoetseng pele tsa laboratori.

Khanyetso e Feteletseng ea Thermal
Maqephe a khalase a Quartz a ka mamella mocheso ho fihlela ho 1100°C ha a sebelisoa khafetsa 'me a ka ba a phahame le ho feta ha a phatloha ka nako e khutšoanyane. Coefficient ea bona e tlase haholo ea katoloso ea mocheso (~5.5 × 10⁻⁷ /°C) e netefatsa khanyetso e ikhethang ea ho phatloha ha mocheso.
Ponaletso e Phahameng ea Optical
Li fana ka ponaletso e ntle haholo ho spectrum ea UV, e bonahalang, le ea IR ho latela sehlopha, ka sekhahla sa phetisetso se fetang 90% libakeng tse ngata tse bonahalang. Sena se li etsa hore li be ntle bakeng sa lits'ebetso tsa photolithography le laser.
Ho Tšoarella ha Lik'hemik'hale
Khalase ea Quartz ha e na matla ho boholo ba li-acid, li-base le likhase tse senyang. Khanyetso ena e bohlokoa bakeng sa libaka tse hloekileng le ts'ebetso ea lik'hemik'hale tse hloekileng haholo.

Ka boima ba Mohs ba 6.5–7, maqephe a khalase a quartz a fana ka khanyetso e ntle ea ho ngoapa le botsitso ba sebopeho, esita le tlas'a maemo a thata.
Ho kenya motlakase
Quartz ke sesebelisoa se setle sa ho thibela motlakase 'me se sebelisoa haholo lits'ebetsong tsa maqhubu a phahameng le tsa motlakase o phahameng ka lebaka la ho se fetohe ha eona ha dielectric le ho hanyetsa ho phahameng.

Lipotso Tse Botsoang Khafetsa ka Likhalase tsa Quartz

P1: Phapang ke efe pakeng tsa quartz e kopantsoeng le silica e kopantsoeng?
A:Quartz e kopantsoeng e hlahisoa ka kristale ea quartz ea tlhaho e qhibilihisitsoeng mochesong o phahameng, ha silika e kopantsoeng e etsoa ka metsoako ea silicon e hloekileng haholo ka ho kenngoa ha mouoane oa lik'hemik'hale kapa hydrolysis. Hangata silika e kopantsoeng e na le bohloeki bo phahameng, phetiso e betere ea UV, le litaba tse tlase tsa litšila ho feta quartz e kopantsoeng.

P2: Na maqephe a khalase ea quartz a ka mamella mocheso o phahameng?
A:E. Maqephe a khalase a Quartz a na le botsitso bo botle ba mocheso 'me a ka sebetsa ka ho tsoelang pele mochesong o fihlang ho 1100°C, ka khanyetso ea nako e khuts'oane ho fihlela ho 1300°C. Hape a na le katoloso e tlase haholo ea mocheso, e leng se etsang hore a hanele haholo ho thothomela ha mocheso.

P3: Na maqephe a khalase a quartz a hanela lik'hemik'hale?
A:Quartz e hanela haholo li-acid tse ngata, ho kenyeletsoa li-hydrochloric, nitric, le sulfuric acid, hammoho le li-solvents tsa organic. Leha ho le joalo, e ka hlaseloa ke hydrofluoric acid le litharollo tse matla tsa alkaline joalo ka sodium hydroxide.

P4: Na nka itšeha kapa ka phunya maqephe a khalase ea quartz ka bonna?
A:Ha re khothaletse ho etsa machining ka ho iketsetsa. Quartz e pshatleha habonolo ebile e thata, e hloka lisebelisoa tsa taemane le lisebelisoa tsa profeshenale tsa CNC kapa tsa laser bakeng sa ho seha kapa ho tjheka. Ho sebetsana ka tsela e fosahetseng ho ka baka ho petsoha kapa liphoso tsa bokaholimo.
