Kremenn\u00e9 trubice<\/a> (zlo\u017een\u00e9 predov\u0161etk\u00fdm z oxidu kremi\u010dit\u00e9ho, SiO2) vykazuj\u00fa chemick\u00fa stabilitu pri vysok\u00fdch teplot\u00e1ch, ktor\u00e1 je ovplyvnen\u00e1 nieko\u013ek\u00fdmi k\u013e\u00fa\u010dov\u00fdmi faktormi. Medzi hlavn\u00e9 faktory patria:<\/p>\n\n\n\n

1. Teplota<\/h4>\n\n\n\n

So zvy\u0161uj\u00facou sa teplotou zost\u00e1va chemick\u00e1 stabilita kremenn\u00fdch trub\u00edc vo v\u0161eobecnosti kon\u0161tantn\u00e1. Pri vysok\u00fdch teplot\u00e1ch (nad 1100 \u00b0C) m\u00f4\u017eu kremenn\u00e9 r\u00farky podlieha\u0165 \u0161truktur\u00e1lnym zmen\u00e1m, ako je deform\u00e1cia mrie\u017eky alebo f\u00e1zov\u00e9 prechody. Kremenn\u00e9 r\u00farky v\u0161ak zvy\u010dajne odol\u00e1vaj\u00fa teplot\u00e1m a\u017e do 1400 \u00b0C bez v\u00fdrazn\u00fdch chemick\u00fdch reakci\u00ed. Z tohto d\u00f4vodu sa kremenn\u00e9 trubice be\u017ene pou\u017e\u00edvaj\u00fa v priemyseln\u00fdch aplik\u00e1ci\u00e1ch, ktor\u00e9 zah\u0155\u0148aj\u00fa extr\u00e9mne teploty, ako je v\u00fdroba polovodi\u010dov alebo vysokoteplotn\u00e9 chemick\u00e9 reakcie.<\/p>\n\n\n\n

2. Atmosf\u00e9ra<\/h4>\n\n\n\n

Stabilita kremenn\u00e9 r\u00farky<\/a> sa l\u00ed\u0161i v z\u00e1vislosti od chemickej atmosf\u00e9ry. V \u010distom kysl\u00edku alebo inertn\u00fdch plynoch, ako je arg\u00f3n alebo dus\u00edk, s\u00fa kremenn\u00e9 trubice ve\u013emi stabiln\u00e9. V atmosf\u00e9re obsahuj\u00facej kysl\u00edk alebo halog\u00e9ny, najm\u00e4 pri teplot\u00e1ch nad 500 \u00b0C, v\u0161ak m\u00f4\u017eu kremenn\u00e9 trubice s t\u00fdmito plynmi reagova\u0165. Kremenn\u00e9 trubice m\u00f4\u017eu napr\u00edklad reagova\u0165 s kysl\u00edkom za vzniku kremi\u010ditanov. T\u00fato reakciu je potrebn\u00e9 zoh\u013eadni\u0165 najm\u00e4 pri priemyseln\u00fdch aplik\u00e1ci\u00e1ch, ktor\u00e9 zah\u0155\u0148aj\u00fa koroz\u00edvne plyny.<\/p>\n\n\n\n

3. Ne\u010distoty<\/h4>\n\n\n\n

Pr\u00edtomnos\u0165 ne\u010dist\u00f4t v kremenn\u00fdch trubiciach m\u00f4\u017ee v\u00fdrazne ovplyvni\u0165 ich chemick\u00fa stabilitu. Napr\u00edklad kovov\u00e9 ne\u010distoty, ako je \u017eelezo a hlin\u00edk, m\u00f4\u017eu pri vysok\u00fdch teplot\u00e1ch reagova\u0165 s oxidom kremi\u010dit\u00fdm za vzniku zlo\u017eit\u00fdch kremi\u010ditanov, \u010do zni\u017euje stabilitu materi\u00e1lu. Na zlep\u0161enie \u010distoty kremenn\u00fdch trub\u00edc sa pri v\u00fdrobe be\u017ene pou\u017e\u00edvaj\u00fa vysoko\u010dist\u00e9 suroviny a \u0161peci\u00e1lne procesy zu\u0161\u013each\u0165ovania. To je obzvl\u00e1\u0161\u0165 d\u00f4le\u017eit\u00e9 v oblastiach, ktor\u00e9 si vy\u017eaduj\u00fa mimoriadne vysok\u00fa \u010distotu materi\u00e1lu, ako je napr\u00edklad optick\u00fd a elektronick\u00fd priemysel.<\/p>\n\n\n\n

4. Zmeny fyzik\u00e1lneho stavu<\/h4>\n\n\n\n

Hoci kremenn\u00e9 r\u00farky<\/a> s\u00fa pri vysok\u00fdch teplot\u00e1ch relat\u00edvne stabiln\u00e9, oxid kremi\u010dit\u00fd m\u00f4\u017ee pri extr\u00e9mnych teplot\u00e1ch a tlakoch podlieha\u0165 zmen\u00e1m fyzik\u00e1lneho stavu. Najm\u00e4 pri teplot\u00e1ch vy\u0161\u0161\u00edch ako 1600 \u00b0C m\u00f4\u017ee kreme\u0148 za\u010da\u0165 m\u00e4kn\u00fa\u0165 alebo sa dokonca roztavi\u0165. T\u00e1to vlastnos\u0165 by sa mala zoh\u013eadni\u0165 v aplik\u00e1ci\u00e1ch zah\u0155\u0148aj\u00facich extr\u00e9mne prostredia, kde je nevyhnutn\u00fd spr\u00e1vny n\u00e1vrh materi\u00e1lu a ochrann\u00e9 opatrenia.<\/p>\n\n\n\n

5. \u010cas<\/h4>\n\n\n\n

Dlhodob\u00e9 vystavenie vysok\u00fdm teplot\u00e1m m\u00f4\u017ee vies\u0165 k postupnej degrad\u00e1cii kremenn\u00fdch trub\u00edc. Najm\u00e4 ak s\u00fa v atmosf\u00e9re pr\u00edtomn\u00e9 reakt\u00edvne chemik\u00e1lie, kremenn\u00e9 trubice m\u00f4\u017eu pomaly str\u00e1ca\u0165 svoju mechanick\u00fa a chemick\u00fa stabilitu. V ur\u010dit\u00fdch priemyseln\u00fdch aplik\u00e1ci\u00e1ch, ako je napr\u00edklad pou\u017e\u00edvanie vysokoteplotn\u00fdch pec\u00ed, sa zlo\u017eenie atmosf\u00e9ry \u010dasto kontroluje a \u010das vystavenia sa minimalizuje, aby sa pred\u013a\u017eila \u017eivotnos\u0165 kremenn\u00fdch trub\u00edc.<\/p>\n\n\n\n

Pr\u00edklad praktickej aplik\u00e1cie<\/h3>\n\n\n\n

Pri v\u00fdrobe vysokoteplotn\u00fdch polovodi\u010dov, kremenn\u00e9 r\u00farky<\/a> sa \u010dasto pou\u017e\u00edvaj\u00fa v procesoch chemick\u00e9ho naparovania (CVD), ktor\u00e9 si vy\u017eaduj\u00fa extr\u00e9mne teploty a presn\u00fa kontrolu atmosf\u00e9ry. Pr\u00edsnou kontrolou vn\u00fatornej a vonkaj\u0161ej atmosf\u00e9ry kremenn\u00fdch trub\u00edc a zabezpe\u010den\u00edm \u010distoty materi\u00e1lu m\u00f4\u017eu v\u00fdrobcovia v\u00fdrazne pred\u013a\u017ei\u0165 \u017eivotnos\u0165 zariaden\u00ed a zv\u00fd\u0161i\u0165 efekt\u00edvnos\u0165 v\u00fdroby.<\/p>\n\n\n\n
