Development of Porcelain Stoneware with Improved Properties Based on Local Raw Materials Using Microsilica. The relevance of developing effective technologies for the production of porcelain stoneware due to the ceramic industry’s need for innovative materials and resource constraints is considered. The aim of the study is defined: to create porcelain stoneware with enhanced characteristics based on local raw materials from the Turkestan region using microsilica – a silicon production waste. An assessment of the region’s mineral raw materials was carried out, the influence of firing temperature (1050−1250°C) and particle dispersity on the material's properties was studied, and compositions of masses with varying microsilica content were developed. It is established that the introduction of 2% microsilica and firing at 1250°C allow for obtaining porcelain stoneware compliant with the ISO 13006 standard: flexural strength – 41.5 MPa, water absorption – 0.02%, frost resistance – 107 cycles. The prospects of using microsilica for the development of the domestic ceramic industry, expansion of the range of competitive products, and utilization of industrial waste are revealed.
