Получены данные по влиянию различных фракций кварцевых песков на последовательность процессов, протекающих при термической обработке шихты, и скорость растворения зерен кремнезема, определяющую продолжительность процесса стеклообразования. С использованием сканирующей электронной микроскопии установлено влияние температурно-временных режимов термической обработки на размеры зерен остаточного кремнезема и степень однородности расплава на стадии стеклообразования. По данным электронно-зондового микроанализа проведены расчеты скорости и времени растворения зерен кремнезема различного фракционного состава в стеклообразующем расплаве. При исследовании процессов стеклообразования и качества листового стекла выявлена возможность использования кварцевого песка расширенного фракционного состава, в том числе включающего зерна размером 0,8–1,25 мм, при варке стекол в высокопроизводительных стекловаренных печах, что позволит более рационально расходовать ограниченные запасы данного сырья.</p></abstract><trans-abstract xml:lang="en"><p>The effect of granulometric composition of silica sand from the Lenindar deposit (Republic of Belarus) on glass-formation processes during the Na2O–MgO–CaO–SiO2 glass system synthesis was studied. The data were obtained on influence of different fractions of silica sand on the sequence of processes occurring during the batch heat treatment and the dissolution rate of silica grains which determines the duration of glass formation. Scanning electron microscopy was used to study the influence of temperature and time modes of the heat treatment on the grain sizes of residual silica and the degree of melt homogeneity at the glass formation stage. Based on the data of electron probe microanalysis, the rate and time of dissolution of silica grains of different fractional composition in the glass-forming melt were calculated. The results of glass formation processes monitoring and the quality of flat glass revealed that the usage of the expanded silica sand fractional composition is possible. This composition can include the grains of 0.8–1.25 mm in size when the glass melting proceeds in high-performance furnaces. That will allow more rational use of limited resources of this raw material.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кварцевый песок</kwd><kwd>листовое стекло</kwd><kwd>концентрация элементов</kwd><kwd>коэффициент диффузии</kwd><kwd>скорость растворения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silica sand</kwd><kwd>flat glass</kwd><kwd>element concentration</kwd><kwd>diffusion coefficient</kwd><kwd>dissolution rate</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Технология стекла.
