Description
(54) СПОСОБ ПОДГОТОВКИ К АНАЛИЗУ НА ГАЗССОДЕРЖАНИЕ(54) METHOD OF PREPARATION FOR ANALYSIS FOR GAS-CONTAINMENT
ПРОБ КРЕМНЕЗЁМАSILICON SAMPLE
3.3
количество газов, растворенных в объеме разных образцов стекол и шихт, могут быть измерены с точностью до некоторой величины, имеющей небольшое посто нное значение.The amount of gases dissolved in the volume of different samples of glasses and charges can be measured with an accuracy of up to a certain value, which has a small constant value.
Так как стенки ампул станов тс пластичными при температурах 140015ОО С , примен ют защитные оболочки ампул из молибдена с целью прадохранеПИЯ ампул от разрыва давлением выдел ющихс при термообработке газов.Since the walls of the ampoules become plastic at temperatures of 140015 60 ° C, the protective shells of molybdenum ampoules are used to preserve the ampoules from rupture of the gases released during the heat treatment of the ampoules.
Ампулы с образцами и пустые ампулы вскрьгаались в объеме блока напуска массспектрометрической установки газового анлиза на основе омегатрона ИПДО-1, и исследовалс состав и количество газов в ампулах .The ampoules with the samples and empty ampoules were scraped in the volume of the inlet block of the EITI-1 omegatron mass spectrometric unit for gas analysis, and the composition and quantity of gases in the ampoules were investigated.
П в и м е р . Навески 0,2 г порошков фракции 0,08-0,1 мм газоплав ленного квацевого стекла помещались в двойные ампулы . Ампулы эвакуировались и после тренировочного прогрева в течение 15 мин при 8ОО С отпаивались в пламени ацетиленовой горелки. Затем отпаивались части двойных ампул и надевались защитные оболочки на загруженные части ампул.П в and me R. Samples of 0.2 g of powders of a fraction of 0.08–0.1 mm of gas-fused quartz glass were placed in double ampoules. The ampoules were evacuated and after training warm-up for 15 minutes at 8OO C they were sealed off in a flame of an acetylene torch. Then parts of double ampoules were soldered off and protective shells were put on loaded parts of ampoules.
При добавлении О,О2 ввс.,,О ь качестве минерализатора образцы полностью превращались в кристабаллит через 1 часWith the addition of O, O2 airs., O as a mineralizer, the samples were completely converted to cristaballite after 1 hour

термообработки при 15ОО С. Ре льтаты анализа газов были следующими (мол:%):heat treatment at 15OO C. The results of the analysis of gases were as follows (mol:%):

Увеличение выдержки до 2 час. при 15ОО С не дало дополнительного прироста количества выделившихс газов. |Exposure to 2 hours. at 15 ° C, there was no additional increase in the amount of gases released. |
Газовый фон пустых ампул не превыи ан 1,5% от количества газсж, выделившихс ; в ампулах с навесками.The gas background of empty ampoules does not exceed 1.5% of the amount of gas released; in ampoules with hinges.
