The paper provides the results of a succession of the development of compositions of ceramic materials with an addition of the Tatar Field expanded vermiculite in order to obtain an effective ceramic brick by different molding processes. The features of creating the structure of ceramic crock are demonstrated, prepared this way. Weak adhesion smooth surfaces of grains of vermiculite to many inorganic binder is eliminated, according to the rule Rebinder, the nature of the raw clay, similar in composition with vermiculite. During plastic molding, gel surface penetrates not only in international grains void, and between the plates of expanded vermiculite within the grain, which strengthens the system. When semi dry pressing need to adjust the quantity of tempering water and apply a press powders with low humidity, little regard to the needs of grains of expanded vermiculite, because of the possibility of elastic expansion and reversible deformation after the termination of the simply press efforts.
