Золь-гель синтез Ta[2]O[5]

Abstract

Relevance of the work was caused by absence information about complex research of regularities of Ta[2]O[5] formation by sol-gel method. Powders of tantal(V) oxide was obtained by sol-gel method from alcohol solution of tantal(V) chloride. In present work by IR spectroscopy, thermal analysis with mass spectrometry and X-ray diffraction the composition of sol and dried gel was determined. It was found that thermal destruction of dried gel at 600 °C leads to obtaining rhombic crystal phase [beta]- Ta[2]O[5].
