摘要： PURPOSE:To provide a quantitative analysis method for analyzing the amount of the unburnt substance remaining in metal oxide powder, capable of determining the amount of the unburnt substance remaining in the produced metal oxide powder, with ease, rapidity, low cost, and high accuracy, without using a time-consuming and expensive chemical analysis or instrumental analysis, etc. CONSTITUTION:In a quantitative analysis of the unburnt substance in the metal oxide powder produced by the manufacture of a metal oxide powder such that a metal powder is ignited so as to form a combustion flame followed by continuously oxidizing and burning the metal powder, the metal oxide powder is mixed with a solvent affinitive to it so as to prepare a suspension. The suspension is subjected to a dispersion processing by means of an ultrasonic cleaner, then being subjected to a classification processing by means of a centrifugal separator, followed by separating the suspension into the layer 11 consisting of a suspension containing the metal oxide powder and the solvent, the layer 12 consisting of the metal oxide powder, and the layer 13 consisting of an unburnt substance. The layer 13 consisting of the unburnt substance is visually compared with a standard specimen prepared in advance, so that the amount of the unburnt substance in the metal oxide powder is determined.
