Effect of pH and Rotational Mixing Time of Slip on the Cracked Reject Ratio for Quartz Ceramic Articles

The effect of the pH and rotational mixing time of slip on the likelihood of the appearance of cracked rejects was determined by means of statistical analysis of data on the preparation of slip from quartz glass and data on ceramic rejects. By means of data on the zeta-potential of slip particles and an examination of the scheme of physicochemical transformations of submicron particles of quartz glass and silica sol in the slip we were able to identify the intervals of optimal values of the pH and rotational mixing time of the slip.
