Abstract

PURPOSE:To obtain the captioned sample which is free from segregation and cracking of the crystal thereof and exfoliates naturally from the bottom part of a vessel by a method wherein the pulverized sample is heated and melted together with a melting agent in the vessel for preparation of the sample, which is made of platinum-gold alloy and whose bottom part is smooth, and flat and later is cooled by the wind blown against the bottom part of the vessel. CONSTITUTION:On preparing the glass-bead sample for the fluorometric X-ray analysis from the pulverized sample, the pulverized sample and the melting agent in a certain ratio are put in the vessel 2 for preparing the sample, which is made of the platinum-gold alloy and whose bottom part is smooth and flat. Next, this vessel 2 is put in an electric furnace, a high-frequency furnace or the like and the sample is heated and melted to be a uniform melt-formed substance 3. After that, the vessel for preparing the sample is removed from the heating source and the wind is blown against the bottom part of the vessel by a blower 1, whereby the aimed sample is obtained. On the occasion of cooling, incombustible gas such as N2, CO2, He may also be blown for cooling, and, when blowing is made against the vessel being rotated, the cooling is made uniform, cracking of the glass bead is further reduced.
