Y. 100)7 January 17, 1964 SUBJECT) SVPRLSKENT TO LEAD IN THE CERAMIC INDUSTRIES To Henbers of the Load Industries Association, Inc,: Encloeod Is a press release and the latest eupplecent to our conus!c data book, LEAD IN THE CERaKIC U.DUSTRIE3. The release, which briefly describes the eupplecent, was sent to the appropriate trade Journal-), newspapers and magazines. The eupplecent has been called to all who now possess the binder, and single copies will be offered in response to inquiries generated by the release and publicity In LEAD carszlne. As we note In the release, it is expected that this eupplecent will bo of assistance not only to researchers In tha electroceramles field, but also in such cisfellaneoua fields as glass, enanels and glazes. Data for ths eupplecent was developed under research directed by tha International Lead Zinc Research Organization and carried out at the Penn sylvania State University, The Supplement was prepared by Jeroce Soith of our staff with the cooperation of f. A.

Considerable effort has been devoted In the eltctroceraaics field towards the development of bodies and glasses with the desired characteristics, and this new publication on phase diagrams gives results of setae of this work. To assist further research and as a basis for irr.ediite application, a one-page summary of important dba in the system PIC--BiO--ligO--EiOj has Just boon issued by the Lead Industries Association Inc 292 Xadiscn Avcr.ue, Kew Tork, N.Y. (10017). Eight diagrems from this system, two teri-ary and six binary, havo boen selocted for publication frets the thesis of J. F. Argyle. Kr. Argyle was working under grants froa the International Lead Zinc Research Organisation at The Pennsylvania State University for the period August, 1958 to June, 1963, and his work was directed by Professor F. A. Hucoel, Head of the Departnent of Ceramic Technology. It is expected that these diagrams will also serve as a basis for further research in such aroas as glass technology, enamels, and glazes. The data shoot was issued as a supplement to the ceramic data book, LEAD IN THE CETIAMIC It'l'.'.'.y'UES. A single copy r j be obtci.nti free of charge by writing the Lead Industries Association at the above address. EPI7WS NCIE. If you would like a copy of tills supplement or if you would like a copy of LEAD IN THE CEPAMIC INIXJSTREIS, ploaoo feel free to write or call.
