The effect of the prescription of highly porous abrasive ceramic masses on their hardness
It is established that the hardness of the highly porous abrasive-ceramics after firing, measured by the acoustic method, affects the content of the ceramic ligament and pore-formers in the form of hollow aluminosilicate microspheres and crushed fruit pits. To a lesser extent the influence of the quantity of abrasive grain in the molded mass. On the basis of statistical data array hardness developed linear regression models due to the sound values of the index from its volume and weight of the main components of the composition of masses of different structure and grain size.
