The results indicated that Yoshida Shirasu is mainly composed of volcanic glass having sharpened edges and sponge- like particles (mean particle size of 1.3 μm). The chemical composition of the Shirasu is 5.22-6.83% Ig.loss, 69.41-70.00% SiO_2, 13.24-13.44% Al_2O_3, 1.58-1.82% Fe_2O_3, 1.32-1.44% CaO, 0.65-0.72% MgO, 3.57-5.36% Na_20, 3.67-5.26% K_2O. Moreover, the mechanochemical properties of ground Shirasu were investigated by reading the change in particle size, adsorption of dye, IR, and XRD.}, pages = {137--144}, title = {シラスの工業的利用に関する研究 (第22報) : 鹿児島県吉田町産シラスの性質とメカノケミストリー}, volume = {28}, year = {1986} }
