概要

• 論文の詳細を見る

• The role of alkali germanates as catalysts in the polymorphic transformation of germanium dioxide was investigated by high-temperature X-ray diffraction method. Lithium germanate and sodium germanate catalyze the transformation in a solid state, the activation energies being larger than 80 kcal/mol. Potassium germanate catalyst plays its role in a liquid state, the activation energy being smaller than that of other catalysts.
