ANNOTATSIYA. Mazkur tadqiqotda tabiiy kvars qumlaridan yuqori tozalikka
ega kremniy olish jarayoni aluminotermik qaytarish usuli asosida o‘rganilgan.
Xomashyoning dastlabki fizik-kimyoviy tavsifi aniqlanib, aralashmalardan tozalash
bosqichlari takomillashtirilgan. Qaytarish jarayonining termodinamik asoslari hamda
harorat va vaqt parametrlarining kremniy hosil bo‘lishiga ta‘siri tahlil qilinib va
reaksiya natijasida hosil bo‘lgan mahsulotning fazaviy tarkibi rentgen difraksion tahlil
(XRD), mikrostrukturasi esa skanerlovchi elektron mikroskopiya (SEM) usullari
yordamida baholangan.Olingan natijalar aluminotermik qaytarish usuli nisbatan past
harorat sharoitida yuqori tozalikdagi kremniy olish imkonini berishini hamda jarayon
parametrlarini takomilllashtirish hamda mahsulot sifatini oshirishda muhim omil
ekanligini ko‘rsatmoqda.
