The Ozawa's generalized time concept and YZ-master plots as a convenient tool for kinetic analysis of complex processes
Original language description
The concept of generalized time in non-isothermal kinetics was introduced by Ozawa in 1965, together with the well-known isoconversional plot, i.e., Ozawa plot. The generalized time is the key concept to tie the kinetic data under varying temperature tothe kinetic relationship at a constant temperature. It is well known that many processes studied by thermal analysis and calorimetry reveal a complex nature. Therefore, the generalized time concept seems to be very useful for the description of the change in the rate behavior depending on the fractional conversion. Using the concept of theta, three kinds of experimental master plots can be formalized in differential, integral, and multiplied forms. Among others, combination of the differential and multiplied master plots, y(alpha) = (d alpha/d theta) and z(alpha) = (d alpha/d theta)theta, show a high performance to discriminate the kinetic model based on the maxima condition of y(alpha (y)*) and z(alpha (z)*). The alpha (y)* - alpha (y)
