Method & Evidence

AimWhat are the optimal formulations and firing temperatures for producing standard porcelains from Ohiya clay for low/high voltage insulators, tiles, and tableware, and what is the economic impact of these optimized designs?

MethodExperimental evaluation, modeling, and desirability optimization

ProcedureThe study involved experimentally evaluating the effects of varying Ohiya clay-feldspar-silica mixes and firing temperatures on key porcelain properties. A desirability optimization methodology was then used to determine standard formulations and optimal firing temperatures for specific product types (insulators, tiles, tableware). The economic viability of these optimized designs was assessed by comparing production costs with market prices.
