Влияние условий осаждения на параметры распределения частиц по размерам и форму частиц порошков гидроксидов и оксидов олова

Abstract

The study is focused on the influence of precipitation conditions on the parameters of size distribution and particle shapes of hydroxide and oxide tin powders. Samples were precipi-tated at the constant pH values of 1.00, 1.50, 1.75, 2.00, 2.25, 2.50 and 3.00. It was found that the pH of the isoelectric point for tin (IV) hydroxide is 2.0. The size and morphology of the particles were determined using laser diffraction and optical microscopy.
