NaX seolitlari eng qimmatli sintetik seolitlardan biri boʻlib, sanoatda ion almashinadigan materiallar, katalizatorlar va adsorbentlar sifatida keng qoʻllaniladi. Shuning uchun uni arzon va ekologik toza xom ashyolardan sintez qilishning tejamkorroq usulini tanlash kerak. Yaxshi kristalllikka ega kaolindan NaX seolitini olish. Bu uchun Angren konnidan uchta tanlangan joydan namunalar (Ik, Ok va Ka) olingan. Tanlangan kaolinit gillari (Ik, Ok va Ka) dastlab toza kukunlarni (75 mkm) oʻlchov birligi olish uchun ehtiyotkorlik bilan boyitilgan. Qayta ishlangan kaolinit gil kukunlari keyin mufel pechida qizdirildi 800 °C haroratda 3,5 soat davomida, 10 °C / mint isitish tezligi bilan. Kaolinit gillarining tegishli metakaolinlarga aylanishi. Keyin hosil boʻlgan metakaolinlar NaOH eritmalari bilan har xil darajada reaksiyaga kirishdi past harorat yordamida mos ravishda 3,0 va 4,0 M konsentratsiyalari NaX seolit kukunlarini ishlab chiqarish uchun gidrotermal transformatsiya. Olingan seolitlar skanerlash
