Measurement of Dissolution Behavior of VO2 in Lead Borosilicate Glasses by X-Ray Powder Diffraction

As a basic study on the temperature-sensitive switching element of VO2 system, dissolution behavior of VO2 in lead borosilicate glass was measured. X-ray diffraction intensity of VO2 was measured by the internal-standard method. A mixed powder of VO2 and lead borosilicate glass was annealed in nitrogen atmosphere, for 10min at 100°C steps from 600° to 900°C, and quenched into liquid nitrogen from the annealing temperature. The X-ray diffraction intensity was found to be proportional to the VO2 concentration in lead borosilicate glass. Dissolution quantity of VO2 was obtained as 0, 19, 38 and 46g per 100g glass at 600°, 700°, 800° and 900°C respectively.
