Development of Standard Formulations for Porcelain Production from Ohiya Clay

Article scientifique 2020 Anglais

Résumé

Abstract Optimal products design for producing standard ceramic porcelain products from Ohiya clay was determined in this study using desirability function analysis. Results revealed that the alumino-silicate constitutes 91% of the total mineralogical composition of Ohiya clay and 42:32:20 at a firing temperature of 1250/1300 oC; 42:33:17 at a firing temperature of 1300 oC; 41:32:27 at a firing temperature of 1000 oC as the optimal mix of the clay, feldspar and silica for producing standard low/high voltage insulators, tiles and tablewares respectively. The production of the 11 kV electric insulator, 400 × 400 mm tile, serving dish at optimal settings are respectively six hundred and twenty-five naira (₦625), three hundred and twenty-two naira (₦322), three hundred and four seven (₦347) against the market prices of one thousand naira (₦1000), three hundred and fifty naira (₦350), four hundred and twenty naira (₦420) respectively. This translates to 60%, 9% and 21% in profit for these products. Hence, adoption of the optimal mixing ratio as well as exploitation of this natural resource is highly recommended.
