Dear Bill:
The polymorphism of the rare earth sesquioxides is discussed in several places in Goldschmidt's papers. The most important reference for your purpose seems to be Goldschmidt, Ulrich, and Bart, Skrifter det Norske Videnskaps Akad. Oslo I. Matem.-Naturid. Klasse, 5, 15 (1925). In the case of gadolinium the type B seems to be made by heating the hydroxide or nitrate to temperatures above 880°C., whereas the type C is obtained at temperatures below about 880°. Type C is cubic, and I feel that it should show the smallest value of Δ. Type B seems to consist of two or more submodifications, one rhombic or monoclinic trigonal and the second trigonal. The crystal structure of the B type is not known. Type A, which is hexagonal, has not been prepared for gadolinium but by consideration of the other rare earths it seems probable that it could be formed at temperatures above about 2500°. From the description of your method of preparation as involving boating to a red heat, it seems to me that you might have either B or C. If you would like a powder photographs taken of your material to decide the question, send me a small sample (0.1 gm.) and I will have it photographed.
With best regards, I am
Sincerely yours,
Linus Pauling
