chapter title A Non-Linear Programming Approach for Formulation of Three-Component Ceramics as a Function of Physical and Mechanical Properties

abstract The simultaneous effect of raw materials type and content on physical and technological properties of a triaxial ceramics system has been studied in the range of values used in industrial practice. The investigation has been carried out using the statistical design of mixture experiments, a special case in response surface methodologies. Ten formulations of the three raw materials selected were used in the experimental design. Those formulations were processed under conditions similar to those found in the ceramics industry: powder preparation (wet grinding, drying, granulation and humidification), green body preparation (pressing and drying) and firing. A non-linear programming approach was applied to minimize the cost of the three-component ceramics, considering optimum ranges of bulk density, bending strength, water absorption and porosity of sintered bodies. A validation experiment was performed to confirm the optimized composition predicted.
