This paper according to the requirements of the unique production process of the "Tangshan bone china" geographic indication products, specified 315 pieces of bone china 8 inch flat produced by 15 different enterprises as the experimental samples. By measuring the tricalcium phosphate content in the prime tyres and the bibulous rate value of white bone china, map out a series of C 3 P-ω detection data points accumulation line chart. Verified by analysis of the qualitative and quantitative relationship between tricalcium phosphate content and bibulous rate of "Tangshan bone china", derived the following conclusions: with the increase of tricalcium phosphate content of "Tangshan bone china", its bibulous rate value increases accordingly, they have approximate linear positive correlation; with 36%∼42% of C 3 P levels corresponding to the bibulous rate numerical range of 0.10%∼0.30%.The research results can provide scientific reference to the manufacturing enterprise for improving the production process and the quality control.
