This book was released on 1968 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of long-term studies on rats and rabbits, injected intratracheally with well-characterized key samples of beryllium oxide prepared by calcining beryllium hydroxide for 10 hours at 500, 1100 and 1600 C, respectively, show clearly that there is a definite gradation in biological response depending upon the oxide administered. Thus, the oxide calcined at 500 C was highly active as judged by histopathological examination of the lungs, incidence of tumors, and translocation of beryllium from the lungs to other tissues. In contrast, the oxide calcined at 1600 C showed only minimal effects. Dose-response studies were carried out, using carefully prepared subsamples of 'respirable particle size' (1 to 5 microns) of the three key oxides; results showed a definite gradation in response which diminishes with decreasing dosages of the administered oxide. Investigations on motor exhaust products show that some samples have chemical, physical, and toxicological properties similar to the beryllium oxide calcined at 1600 C. On the other hand, other samples are heterogeneous, contain considerable quantities of water-soluble beryllium, and vary in toxicity. The mechanism of toxic action of beryllium oxide was investigated through study of chemical and physical properties, solubility and adsorption studies, serum electrophoretic analyses, and immunological experiments. Suggestions are made for further studies. (Author).

Book excerpt: S>The primary objective of the literature search was to determine the best values for the properties involved in the thermal stress parameter. Comparison of data from various investigators indicates that thermal expansion of beryllia is independent of density. A wide variation was found in the thermal conductivity values of beryllia. Graphs and tables are presented which summarize and compare data from various sources. A bibliography of 53 references for some of the major items of the stress parameter (thermal expansion, thermal conductivity, and modulus of elasticity) as well as for general properties of beryllia is given to books, journals, and reports published from 1914 to 1960.
