The most important characteristic of suspensions, which determines their variety of properties, is the volume phase composition [i, 2]. The significant factors, in particular, are the volume concentration, within the system, of kinetically free CWk and bonded liquids CWs.They are determined by the critical concentrations CVc r [i], and depend on the nature of the material and also on the various technological factors in obtaining the actual suspension. When the suspension is stabilized by changing the values CVcr, CWk, and CWs,it becomes possible to regulate their properties within wide limits. In most cases a high degree of system stabilization is necessary, which means we can obtain semifinished articles or bonds of the maximum density and strength with low shrinkage during shaping (structure formation). However, in a number of cases there is a need for partial coagulation of the suspension, e.g., in producing mineralized foams, casting systems with foamed polystyrene, etc. In this case we need to develop a certain strength in the structure, i.e., a certain yield point that is required to stabilize the system. When we do not need the maximum density in the green ware, partial coagulation may prove to be useful for suspensions used for casting (e.g., for accelerating the molding process).As demonstrated in [I], a decisive effect is exerted on the volume phase characteristics of the suspensions and on the production technology by the chemical activity of the original substances; this effect is indirectly characterized by the ionic potential IP (Z/R). Thus, if for the suspensions based on substances with low and medium IP values the maximum deflocculation effect is attained by means of electrolytes or surfactive agents (colloidal-chemical gravitational blending (rheological method)~ Although the first method has been studied many times and many years ago [3][4][5], the rheological method, studied in our work in detail [6][7][8], has been previously underestimated; there is certain information, however, on its effectiveness for obtaining porcelain and earthenware suspensions [9] and carbide suspensions [i0]. This method is considered by the present authors as a special technological operation, tentatively called "stabilization," facilitating an additional reduction in the viscosity, an increase in the sedimentation resistance of the suspension with a corresponding rise in the density, and an increase in strength of the casts based on the slips. In the case of thixotropic or maximum-concentrated suspensions, blending tends to increase their density (due to the removal of air trapped when the slip is being ~, made).This article presents a critical assessment of the degree of stabilization or coagulation, and provides new experimental data on the stabilization of the above two methods and also the means of combining them. We studied the aging of ceramic, prestabilized suspensions, and propose an account of the mechanism.Stabilization of the Suspension. Considering that the task of deflocculating (or stabilizing) a sus...
