Ka lilemo tse ngata, monna o batlile ho bopa khalase e bonaletsang tse ngata le manganga ho lintho tse ngata tse kotsi. Ka lebaka la ntlafatso targeted hlaha quartz khalase - le mofuta o mocha ka ho feletseng ba lintho tse bonahalang le litšobotsi tse amang ka ilibana. Mohlomong u ka khalase ena e tla fumana tataiso ea ntshetsopeleng eketsehileng ba moloko oa batho. Quartz khalase - sehlahiswa qhibiliha oxide e bo hloekileng ka silicon (Sio _2). Ho fapana le khalase tloaelehileng, boitsebiso boo e ka boemo amorphous, i.e. bo se na nepahetseng qhibiliha mocheso le ha halefile ho tloha o tiileng ho tsoela mokelikeli boemo butle-butle. Haholo-holo ka lebaka la ho thepa ena ea quartz kapa silica, khalase fumanoa joalo kopo lohle indastering.

The thepa ka khalase quartz

Metaborate khalase e na le tlase motlakase conductivity, kahoo, ho e atisa ho sebelisoa e le dielectric ka disebediswsa motlakase thata. Ba ka sehloohong le molemo thepa, eo ka eona ho ba le quartz khalase ka arotsoe ka lihlopha tse tharo:

1. Thermal. Ho hanyetsa mocheso phahameng ^(ka 1200 C), e phahameng coefficient la boela la atolosoa mogote (makhetlo 15 phahameng ho feta tsa khalase ba tloaelehileng) ho feta ho bakoa ke ho hanyetsa liphetoho ka tšohanyetso le bohlokoa mocheso (bakeng sa tlhahiso ea leqhoa-metsi a folisoa le molapo).
2. Lik'hemik'hale. Khalase lik'hemik'hale nke lehlakore, ha e itšoara joang le alkalies tsohle le acid ntle acid e phosphoric le asiti hydrofluoric (ba itšoara joang e qala ka mocheso le ka holimo ^ka 300 C).
3. Optical. The refractive index of khalase silica ke makhetlo a 150 ka tlaase ho feta ea tloaelehileng (n g _{ea e} = 1,46). Ka lebaka lena e ke ka ho phethahetseng fetisetsa se feela letsatsi le khanya tlwaelehileng, empa ha e boloke mahlaseli leha e le efe go la la kapa mahlaseli.
