Kvarts (SiO\u2082) -material liknar mycket glas vid f\u00f6rsta anblicken, men det som \u00e4r mer speciellt \u00e4r att vanligt glas best\u00e5r av m\u00e5nga komponenter (s\u00e5som kvartssand, borax, borsyra, barit, bariumkarbonat, kalksten, f\u00e4ltspat, soda etc.). sammans\u00e4ttning, medan kvarts endast inneh\u00e5ller SiO\u2082, och dess mikrostruktur \u00e4r ett enkelt n\u00e4tverk som best\u00e5r av kiseldioxid tetraedriska strukturella enheter.Eftersom m\u00e4ngden metallf\u00f6roreningar som finns i kvarts \u00e4r mycket liten och dess egen renhet \u00e4r extremt h\u00f6g, har kvarts i sig egenskaper och f\u00f6rdelar som annat glas inte kan visa, och \u00e4r k\u00e4nt som \"kronan\" i glasmaterial. Till exempel, n\u00e4r det g\u00e4ller v\u00e4rmebest\u00e4ndighet, kommer kvarts inte att brista \u00e4ven om den placeras i vatten omedelbart efter att ha br\u00e4nts r\u00f6d i elden, medan vanligt glas inte kommer att brista i vatten efter att ha br\u00e4nts r\u00f6tt, men kommer att rivas s\u00f6nder s\u00e5 snart det br\u00e4nns. Mer specifika f\u00f6rdelar \u00e4r f\u00f6ljande:
1. Motst\u00e5nd mot h\u00f6g temperatur. Mjukningspunktstemperaturen f\u00f6r kvartsglas \u00e4r cirka 1730 \u2103, den kan anv\u00e4ndas under l\u00e5ng tid vid 1150 \u2103 och den h\u00f6gsta temperaturen kan n\u00e5 1450 \u2103 p\u00e5 kort tid.<\/p>\n\n\n\n
2. Korrosionsbest\u00e4ndighet. Med undantag f\u00f6r fluorv\u00e4tesyra har kvarts med h\u00f6g renhet n\u00e4stan ingen kemisk reaktion med andra syror. Vid h\u00f6g temperatur \u00e4r den resistent mot angrepp av svavelsyra, salpetersyra, saltsyra, kungsvatten, neutrala salter, kol och svavel. Dess syrabest\u00e4ndighet \u00e4r 30 g\u00e5nger h\u00f6gre \u00e4n f\u00f6r keramik och 150 g\u00e5nger h\u00f6gre \u00e4n f\u00f6r rostfritt st\u00e5l, s\u00e4rskilt dess kemiska stabilitet vid h\u00f6ga temperaturer, som inte \u00f6vertr\u00e4ffas av n\u00e5got annat tekniskt material.<\/p>\n\n\n\n
3. Bra termisk stabilitet. Den termiska expansionskoefficienten f\u00f6r kvarts med h\u00f6g renhet \u00e4r extremt liten och den t\u00e5l allvarliga temperaturf\u00f6r\u00e4ndringar. Kvartsen med h\u00f6g renhet v\u00e4rms upp till cirka 1100 \u2103 och den kommer inte att brista i vatten med normal temperatur.<\/p>\n\n\n\n
4. Bra prestanda f\u00f6r ljus\u00f6verf\u00f6ring. H\u00f6grenad kvarts har god ljus\u00f6verf\u00f6ring i hela spektralbandet fr\u00e5n ultraviolett till infrar\u00f6tt, och den synliga ljus\u00f6verf\u00f6ringen \u00e4r \u00f6ver 93%, s\u00e4rskilt i det ultravioletta spektralomr\u00e5det, kan den maximala \u00f6verf\u00f6ringen n\u00e5 mer \u00e4n 80%.<\/p>\n\n\n\n
5. Bra elektrisk isoleringsprestanda. Motst\u00e5ndsv\u00e4rdet f\u00f6r kvarts med h\u00f6g renhet \u00e4r 10 000 g\u00e5nger det f\u00f6r vanligt kvartsglas. Det \u00e4r ett utm\u00e4rkt elektriskt isoleringsmaterial och har goda elektriska egenskaper \u00e4ven vid h\u00f6ga temperaturer.<\/p>\n\n\n\n
Tack vare dessa utm\u00e4rkta fysikaliska och kemiska egenskaper anv\u00e4nds kvartsmaterial med h\u00f6g renhet i stor utstr\u00e4ckning inom modern elektronisk teknik, halvledare, kommunikation, elektriska ljusk\u00e4llor, solenergi, h\u00f6gprecisionsm\u00e4tinstrument f\u00f6r nationellt f\u00f6rsvar, fysikaliska och kemiska laboratorieinstrument, k\u00e4rnenergi, nanoindustri etc. S\u00e4rskilt i den snabbv\u00e4xande halvledarindustrin har storleken p\u00e5 kiselskivor \u00f6kat, s\u00e5 chiptillverkare har \u00f6kat efterfr\u00e5gan p\u00e5 olika komponenter gjorda av kvarts. Det b\u00f6r dock ocks\u00e5 noteras att f\u00f6r att f\u00f6rhindra kontaminering under bearbetningen m\u00e5ste kvartsmaterialets h\u00f6ga renhet s\u00e4kerst\u00e4llas under anv\u00e4ndningen<\/p>","protected":false},"excerpt":{"rendered":"
