Kvarco (SiO\u2082) med\u017eiaga i\u0161 pirmo \u017evilgsnio labai pana\u0161i \u012f stikl\u0105, ta\u010diau ypatingiau yra tai, kad paprastas stiklas sudarytas i\u0161 daugelio komponent\u0173 (pvz., kvarcinio sm\u0117lio, borakso, boro r\u016bg\u0161ties, barito, bario karbonato, kalkakmenio, feld\u0161pat\u0173, kalcinuotos sodos ir kt.). ), o kvarco sud\u0117tyje yra tik SiO\u2082, ir jo mikrostrukt\u016bra yra paprastas tinklas, sudarytas i\u0161 silicio dioksido tetraedrini\u0173 strukt\u016brini\u0173 vienet\u0173. kadangi kvarco sud\u0117tyje esan\u010di\u0173 metalini\u0173 priemai\u0161\u0173 kiekis yra labai ma\u017eas, o jo paties grynumas itin didelis, pats kvarcas turi savybi\u0173 ir prana\u0161um\u0173, kuriais negali pasi\u017eym\u0117ti kitas stiklas, ir yra vadinamas stiklo med\u017eiag\u0173 \"kar\u016bna\". Pavyzd\u017eiui, kalbant apie atsparum\u0105 kar\u0161\u010diui, kvarcas nesprogsta, net jei i\u0161 karto po to, kai jis raudonai sudeginamas ugnyje, \u012fdedamas \u012f vanden\u012f, o paprastas stiklas nesprogsta vandenyje po to, kai jis raudonai sudeginamas, bet subyra i\u0161 karto po to, kai sudeginamas. Konkretesni privalumai yra \u0161ie:
1. Atsparumas auk\u0161tai temperat\u016brai. Kvarcinio stiklo mink\u0161t\u0117jimo temperat\u016bra yra apie 1730 \u2103, jis gali b\u016bti ilgai naudojamas 1150 \u2103 temperat\u016broje, o auk\u0161\u010diausia temperat\u016bra per trump\u0105 laik\u0105 gali pasiekti 1450 \u2103.<\/p>\n\n\n\n
2. Atsparumas korozijai. I\u0161skyrus fluoro vandenilio r\u016bg\u0161t\u012f, didelio grynumo kvarcas beveik nereaguoja su kitomis r\u016bg\u0161timis. Auk\u0161toje temperat\u016broje jis atsparus sieros r\u016bg\u0161ties, azoto r\u016bg\u0161ties, druskos r\u016bg\u0161ties, aqua regia, neutrali\u0173 drusk\u0173, anglies ir sieros poveikiui. Jo atsparumas r\u016bg\u0161tims yra 30 kart\u0173 didesnis nei keramikos ir 150 kart\u0173 didesnis nei ner\u016bdijan\u010diojo plieno, ypa\u010d jo cheminis stabilumas auk\u0161toje temperat\u016broje, kuriam neprilygsta jokia kita in\u017einerin\u0117 med\u017eiaga.<\/p>\n\n\n\n
3. Geras terminis stabilumas. Gryno kvarco \u0161iluminio pl\u0117timosi koeficientas yra labai ma\u017eas, tod\u0117l jis gali atlaikyti didelius temperat\u016bros poky\u010dius. Didelio grynumo kvarc\u0105 \u012fkaitinus iki ma\u017edaug 1100 \u2103, jis nesprogsta \u012f normalios temperat\u016bros vanden\u012f.<\/p>\n\n\n\n
4. Geras \u0161viesos pralaidumas. Didelio grynumo kvarcas gerai praleid\u017eia \u0161vies\u0105 visoje spektrin\u0117je juostoje nuo ultravioletin\u0117s iki infraraudonosios spinduliuot\u0117s, o matomos \u0161viesos pralaidumas vir\u0161ija 93%, ypa\u010d ultravioletin\u0117je spektrin\u0117je srityje, did\u017eiausias pralaidumas gali siekti daugiau kaip 80%.<\/p>\n\n\n\n
5. Geros elektros izoliacijos savyb\u0117s. Didelio grynumo kvarco var\u017eos vert\u0117 10 000 kart\u0173 vir\u0161ija \u012fprasto kvarcinio stiklo var\u017e\u0105. Tai puiki elektros izoliacin\u0117 med\u017eiaga, pasi\u017eyminti geromis elektrin\u0117mis savyb\u0117mis net auk\u0161toje temperat\u016broje.<\/p>\n\n\n\n

Ypa\u010d spar\u010diai augan\u010dioje puslaidininki\u0173 pramon\u0117je did\u0117ja silicio plok\u0161teli\u0173 dydis, tod\u0117l lust\u0173 gamintojai didina \u012fvairi\u0173 i\u0161 kvarco pagamint\u0173 komponent\u0173 paklaus\u0105. Ta\u010diau taip pat reik\u0117t\u0173 pa\u017eym\u0117ti, kad, siekiant i\u0161vengti u\u017eter\u0161imo perdirbimo metu, turi b\u016bti u\u017etikrintas didelis kvarco med\u017eiagos grynumas naudojimo metu<\/p>","protected":false},"excerpt":{"rendered":"
