APPLICATION OF THE ISHIKAWA DIAGRAM FOR THE IMPLEMENTATION OF THE TECHNOLOGY OF OBTAINING ELECTROCERAMIC MATERIAL FROM NATURAL KAOLINITES OF THE ORENBURG REGION

The development of ceramic materials requires a rigorous metrological approach to manage uncertainty at all stages of production and enable informed decision-making based on reliable data. The article proposes the use of Ishikawa Diagrams to quantify the contribution of each technological factor to the overall error in the properties of the final product. This allows us to systematize sources of uncertainty, minimize risks, and improve the reproducibility of properties during scaling. The main metric is the assessment of the uncertainty of measurements of the structural parameters of ceramics. The study was conducted on functional ceramics made from kaolinite raw materials from the Orenburg region using morphometry, chemical analysis, physical measurements and modeling. The analysis of the structure-property cause-and-effect relationships and the application of the Ishikawa Diagram revealed the key groups of factors influencing the error. The result was an engineering-based method for producing electroceramics with specified characteristics.
