[ad. G. shandit (P. Ramdohr in Sitzungsber. d. Deutsch. Akad. d. Wissensch. zu Berlin (Math.-naturwissensch. Kl.) 1949 (1950) vi. 26), f. the name of S. J. Shand (1882–1957), Scottish geologist: see -ite1.]
A sulphide of nickel and lead, Ni3Pb2S2, found as yellow rhombohedral crystals.
1950Amer. Mineralogist XXXV. 450 On receiving this result Dr. Ramdohr intimated in a private communication (Nov., 1949) that he proposed to name the new mineral shandite, after Professor S. J. Shand,..who had suggested..the study of the Insizwa nickel ores which led to the discovery of parkerite. Ibid., Two lots of artificial shandite were prepared by fusing charges of 1 gm. and 2 gm. of the powdered elements in the proportions 3Ni:2Bi:2S. 1968I. Kostov Mineralogy 117 Shandite has a distorted spinel structure, the nickel atoms being arranged along the pseudocubic diagonals; this explains its ferromagnetic properties. |
