Abstract: This invention relates to producing aluminum by electrolysis of a melt and can be used in the process control of an electrolyte composition by quantitative X-ray phase analysis (XRD) of potassium-containing electrolyte with calcium or calcium and magnesium additives.

The weighted quantities are mixed and placed in a furnace (650-750° C. for 20-40 minutes) to dissolve sodium fluoride in the sample and recrystallize the sample with the desired phase composition. The doped sample is placed in a furnace (420-450° C) and held for 15-30 minutes. The doped sample is removed from the furnace and allowed to air cool. The phase composition of the doped sample is analyzed by any quantitative X-ray phase method.

Abstract: To accurately measure a tread radius of a rotating tire. A method for measuring a tread radius has a tread radius measuring process which comprises a measurement step, an averaging step, and a calculation step. In the measurement step, the radial distances from three laser displacement meters to the tread surface of the rotating tire are measured to obtain radial distance data y1, y2, y3 whose number is m per the entire circumference of the tire. In the averaging step, an averaged value y1N, y2N, y3N is obtained by averaging the remaining radial distance data from which noise data have been removed by performing a smoothing process on the number m of the radial distance data y1, y2, y3. In the calculation step, a tread radius TR is calculated from the averaged values y1N, y2N, y3N and the distances x1, x2, x3 of the laser displacement meters in the axial direction of the tire.
