Abstract
An overview is given of the works on the creation of original high-precision oscillation methods for an integrated study of physicochemical characteristics and crystallization/melting of solutions and melts. Some experimental results are presented for viscosity and crystallization/melting in the region of stable and metastable states at high temperatures. Dozens of new compounds and phases are found in the studied oxide systems. It is shown that one high-precision experiment can determine more than ten parameters and characteristics of the studied systems in the region of stable and metastable states. In many cases the proposed oscillation methods are found to be much more accurate and informative than the existing methods.
