Abstract

1,075,177. Synthetic garnet. WESTERN ELECTRIC CO. Inc. June 30, 1964 [July 10, 1963], No. 26927/64. Heading H1H. Bismuth substituted garnets of formula Bi x M 3-x [Fe y Mt1 2-y ](Fe z M11 3-z )O 12 where M represents cations of, say, the rare earths, alkaline earth metals, manganese in dodecahedral garnet sites, M1 and M11 represent cations of e.g. titanium, zirconium, hafnium, magnesium, zinc, gallium, indium, silicon, germanium, tin chromium, manganese, cobalt, nickel, scandium, aluminium in octahedral and tetrahedral sites respective, x is 0.05 to 1À5, y is 1 to 2, z is 0À5 to 3.0 and at least 2À5-y, are synthesized by mixing stoichiometric proportions of the oxides, or oxide equivalents, of each cation and firing the mixture at 900 C. to 1400 C. to form a single phase garnet. The starting material may be precalcined at 500 C. increasing to 900 C., e.g. for I hour, and successively ground and fired over a variety of temperatures and times with, say, increase or decrease in temperature, cooling, regrinding and mixing between each temperature variation. A bismuth excess of up to 10% may be added to the starting material to compensate for vaporization losses, or extra bismuth added at a stage in the firing schedule, or the container may be sealed off during firing or an internally introduced bismuth-containing atmophere used.
