First international minerals exhibition
Semiconductors materials will be excluded. Technical sessions will cover the followinotooics: I. Recycling of materials: hazards to chemical composition of both ferrous and non-ferrous alloys as a result of tramp element accumulation: predicted long-term changes in content of particolar residual ele’ments. 2. Fabrication: effect of res’idual impurities on hot shortness, liquidation crackin’g, weld reheat cracking, etc. 3. Performance in servimce: nature and role of minor elements in creep cavitation, temper brittleness, intergranular fatigue, ductility troughs in non-ferrous materials, hydrogen occlusion, irradiation induced voids and swelbing, etc. 4. lmprovement of properties: remedial processes for damaging residuals; assessment of tolerance in bulk impurity levels; beneficial effects of addsitives in high-temperature oxidation, creep performance of nickel-base and austenitic steels, and in other- properties.

IVth INTERNATIONAL SYMPOSIUM ON SCIENCE AND RESEARCH IN SILICATE CHEMISTRY The Symposium will take place in BRNO on May 15-17, 1978. Topics of the Symposion: al Vitreous phase in silicates b) Hydrosilicates al The vitreous chase forms a very important part of the microstructure of a great deal of eihcate products. The purpose of the Symposion’is to discuss the problelms of the vitreous phase inception, its properties, its identification by means of various physical and chemical methods and its behaviour under different thermal conditions. b) Natural and synthetic hydrosilicates represent important initial components in the silicate production and also a microstructure portion of important silicate products in the field of binding materials. In continuity with the lllrd SILICHEM, the progress will be discussed in the field of research of natural and synthetic hydrosilicates and their contribution to the technology.

The organizers retain the right to select from the papers submitted those acceptable for presentation.
FRACTURE MECHANICS PAPERS INVITED The ASTM 11th National Symposium on Fracture Mechanics will be held June 12-14, 1978, at Virginia Polytechnic Institute, Blacksburg, Va. Papers are invited on all aspects of fracture, including theoretical develop
the mAssociation Francaise de Calorimetric et d’Analyse Thermiquem (AFCAT) and by the Italian Group of = International Confederation for Thermal Analysis * (I.C.T.A.). The themes of J.C.A.T. ‘78 are: I. Thermochemistry of Iinteractions at the interfaces: 2. Thermochemistry of transformations in materials; 3. Thermochemistry of systems of biological interest. The scientific sessions will be open by plenary lectures. The number of papers is limited to 36. with 20 minutes time allowed including discussion. The papers may be given in English language. All $mitted papers will be acknowledged subjected to refeering before acceptance. Reprints of conferences and papers will be available before the meeting. During the Symposium the E. Calvet award, recently founded by the A.F.C.A.T. will be assigned. An exhibition of apparatus for calorimetry, thermal analysis and data orocessing, is also planned. Information: Prof. G. Della Gatta, J.C.A.T. ‘78 Organizing Committee Secretary, lstituto di Chimica Generale ed Inorganica. Facolta di Farmacia, Via Pietro Giuria 9. I-10125 Torino (Italy) - Tel. (011) 657.000/682.205.

FIRST INTERNATIONAL MINERALS EXHIBITION A new international exhibition, Minerals 79 International. will take place in Hall 3A of the National Exhibition Centre, Birmingham, England, from Monday, June 18th to Friday, June 22, 1979. The exhibition will include actual minerals [but not metal-bearing ores or fossil fuels) as well as the machinery used to extract and process them. The latest equi,pment for drilling, refining, separating, classifying, crushing, grinding, calcining, drying and storing minerals will be seen alongside highprecision analytical and quality-control instruments. The exhibition will also provide a un’ique market-place for the display of the minerals themselves from rare earths and purified metal salts and oxides to non-metallic materials for use in the steel,making, foundry, paint, plastics, rubber, construction, ceramic and chemical industrtis. Minerals 79 International is organised by International Symposia & Exhibitions Ltd. (an Industrial Newspapers Group Company) of Redhill. Surrey, England. manufacturers and traders Suppliers, from all over the world will occupy some 4500 m2 of actual display space at Europe’s new exhibition complex in Birmingham, and the show will be of importance to all concerned with the use of production of general and highquality industrial minerals.
