Thermal Decomposition of Solids and Melts

Thermal Decomposition of Solids and Melts describes the results of investigations into the mechanisms and kinetics involved in the thermal decomposition of solid and liquid substances via thermochemical analysis (TA). The main features of these thermal decomposition reactions are explained within and the observed anomalies are interpreted. New methods of TA measurement and calculation have been developed, which permit the precision and accuracy of determination of kinetic parameters to be increased substantially. Reliable kinetic characteristics have been obtained and the decomposition mechanisms for several substances have been interpreted. These include different classes of compounds:

• crystalline hydrates

• oxides

• hydroxides

• nitrides

• azides

• nitrates

• sulfates

• carbonates

• oxalates

This book is intended for advanced undergraduates, researchers, and technologists working in the fields of engineering, metallurgy, chemistry, and material science.

Auteur
Professor and Head of the Analytical Chemistry department at St. Petersburg State University, Russia.

Résumé
The appearance of this English edition of my book, ?rst published in Russian in mid-2006, is related to the help and support of two prominent scientists: Professor Michael Brown (Rhodes University Grahamstown, South Africa) and Dr. Judit Simon (Budapest University of Technology and Economics, Hungary). The story is as follows. In the winter of 2006, in the process of exchange of views by email with Michael on some problems of decomposition kinetics, I asked him about the possibility of publishing my book in English. He s- gestedthatIshouldcontactJudit,theSeriesEditorofHotTopicsinThermal Analysis and Calorimetry. My application was kindly accepted, considered, and approved. As a result, Judit strongly recommended this book to Springer for publication, and Michael kindly agreed to help me with linguistic impro- ments of my hurriedly translated book. In the process of editing, he made some critical comments and questions, which stimulated me to improve and clarify the text, but we did have to agree to put our di?erences of scienti?c opinions aside so as not to delay the process. Without this invaluable help, this book would not be as readable as I hope it is now. The author uses this opportunity to express his sincere thanks to Michael and Judit for their signi?cant help and support. Although only about a year has gone after the preparation of the original edition of the book (in Russian), this English version of the manuscript has undergone considerable revision. These changes refer to Sections2. 2, 2.
