CALCINATION TEMPERATURE DETERMINATION METHOD OF INORGANIC BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a calcination temperature determination method of an inorganic base material by which calcination temperature can be accurately recognized even when the inorganic base material is calcined in a calcination furnace of an optional system, even when the inorganic base materials are stacked and calcined and even when the inorganic base material is calcined at any temperature.

SOLUTION: This invention is related to the calcination temperature determination method of the inorganic base material 1 when the inorganic base material 1 is subjected to calcination treatment. A relation of calcination temperature to color difference between color of the inorganic base material 1 before calcination treatment and color of the inorganic base material 1 after calcination treatment at two or more stages of temperature is obtained in advance. After calcination treatment, color of the inorganic base material 1 is measured to obtain color difference between it and color of the inorganic base material 1 before calcination treatment and obtained color difference is collated with the relation of calcination temperature to color difference to determine temperature of calcination treatment of the inorganic base material 1.
