V pr\u00edpade laborat\u00f3rnych zariaden\u00ed a priemyseln\u00fdch reaktorov, ktor\u00e9 pou\u017e\u00edvaj\u00fa kremenn\u00e9 trubice, by to mohlo vies\u0165 k poruch\u00e1m zariadenia alebo ohrozeniu bezpe\u010dnosti. Pri r\u00fdchlych procesoch zahrievania a chladenia je koncentr\u00e1cia nap\u00e4tia n\u00e1chylnej\u0161ia na praskliny alebo dokonca na rozbitie kremenn\u00fdch trub\u00edc, \u010do m\u00f4\u017ee sp\u00f4sobi\u0165 v\u00fdrobn\u00e9 nehody.<\/p>\n\n\n\n
