Thermal Analysis C [antikvár]

FOREWORD Interest in thermal analysis continues to increase. Although the emphasis has tended to move over the past decade or so from instrumentation and technique to applications — largely because of the introduction of an extensive rangé of reliable commercial equipment. The interest in what might be termed the less-common methods has led to those assuming increasing importance. Emanation thermal analysis, the principai method considered in this volume, originated in the work of Ottó Hahn in 1936, but it was generally little known and investigations using it were relatively few and in a limited field until its wider potentialities were appreciated by Vladimír Balek in the late 1960's. During the past decade Dr. Balek has brought the technique to the notice of all thermal analysts and the facts that commercial instruments are now available and that somé 300 papers could be cited in a review of the method, its variants and its applications in 1978 are proofs of the success with which Dr. Balek and those he inspired have single-mindedly pursued developments in methodology and applications. No-one would indeed now deny that emanation thermal analysis, like other thermoanalytical techniques, can yield information that cannot readily be obtained otherwise. The Nomenclature Committee of the International Confederation for Thermal Analysis in their first report in 1969 made a generál recommendation that the term "analysis" should not be used in the names of individual techniques if it could be avoided, since its inclusion tends to suggest a diagnostic quality that the methods do not necessarily possess. Exceptions had to be made to this rule from early on, because somé names were so widely used and accepted that they could not be altered — e.g. it is difficult to conceive of "differential thermometry" being accepted in place of "differential thermal analysis", even although the former name is factually accurate. When the Committee came, in the period 1975-1977, to consider "emanation thermal analysis", they alsó had to accept the fact that, due to Dr. Balek's missionary enthusiasm, the name could not be supplanted despite the fact that it included the undesirable (from their viewpoint)
