Ceramic materials are widely utilized in construction and aerospace due to their mechanical strength, thermal resistance, and longevity. With increasing demand for high-quality finishing products and a global shift toward efficient resource use, it is vital to develop innovative technologies for porcelain stoneware manufacturing. This study focuses on improving the production process of porcelain stoneware in Kazakhstan by integrating microsilica into formulations based on natural raw materials from the Turkistan region. Microsilica, a by-product of ferrosilicon and metallurgical slag processing, has shown great potential in enhancing strength, durability, and water resistance in ceramic compositions. The research includes the characterization of silicon-containing minerals and other types of local geological raw materials. Several new ceramic mass formulations were developed, and the resulting porcelain stoneware samples were tested under laboratory conditions. The influence of technological parameters on the physical and mechanical properties of the final products was systematically analyzed. As a result, tile materials intended for wall and floor applications were successfully produced using natural resources from Turkistan. These tiles demonstrated improved flexural strength (up to 41 MPa), extremely low water absorption (0.023%), and enhanced frost resistance (up to 107 freeze–thaw cycles). Additionally, reduced water absorption contributed to decreased shrinkage during firing and better dimensional stability. The findings confirm that local Turkistan raw materials, when combined with microsilica, provide a promising pathway for the production of high-performance porcelain stoneware. This approach supports the advancement of Kazakhstan’s ceramic industry while promoting sustainable practices through the utilization of industrial by-products.
