“…The latter composition was confirmed in the subsequent studies of [1898Ker], [1900Lan], and[1906Gun]. The investigations of [1900Ker] and[1910Smi] pointed rather to the crystal formula Hg ∼12 Sr. [1974Bru] reported, in addition to Hg 11 Sr, the existence of Hg ∼13 Sr, but the authors were not able to obtain either its pure crystal form or the proper XRD patterns for evidence. [1998Bie] and[1999Bie] repeated thermal analyses and XRD experiments in the Hgrich composition range and found irrefutably that Hg 11 Sr peritectically decomposes at 63 ± 3°C.…”
