Conclusions
A method of determining the grain composition of suspensions of vitreous silica using a liquid sedimentograph has been developed and introduced at the Central Plant Laboratory of the Podolsk Refractory Products Plant. The results of the analysis can be evaluated from the tangent of the angle the straight line makes with the abscissa on the log-probability graph and the average surface diameter of the particles. The relative error in the determination of the average-surface diameter is ≤12%.
Using this method it is possible to determine the disperseness of the suspensions made from Al2O3 and other materials characterized by a grain composition between 0.5 and 100μm.
