Abstract
In the antacid activity test, artificial aluminum silicate differs very much from aluminum hydroxide gel in neutralizing velocity and the total quantity of comsumption of 0.1N-HCl. This difference occurs also in the series of aluminum silicate which change the pH condition of co-precipitation or the composition of aluminum.
Here aluminum silicate samples prepared by various available methods were measured by X-ray diffraction, IR-ray absorption and differential thermal balance.
Furthermore, the shapes and sizes of this first and aggregate particles were estimated by observing the electron microscope photograph. As the result obtained, the above mentioned antacid property of artificial aluminum silicate has effectively been explained comparatively in its bonding state, in the aggregate shapes of its particles and in its electrically charged state at co-precipitation.
