temperature of the 4 minerals in the spheroid wenjiite → kangjinlaite → zhiqinite + badengzhuite is consistent with relationships reported in 9 binary systems containing intermetallic compounds of Ge and Sn isostructural with Mn 5 Si 3 and Ho 11 Ge 10 , in 8 of which the Mn 5 Si 3 analogue melts congruently, whereas the Ho 11 Ge 10 analogue never does. Instead the Ho 11 Ge 10 analogue melts peritectically, generally to an Mn 5 Si 3 analogue and less commonly to compounds with 5:4 stoichiometry. Final crystallization of the spheroid to zhiqinite + badengzhuite is expected to be well below the temperature of 1500 °C for the congruent melting of zhiqinite in the Ti-Si system, i.e. in the range of ~1100 -1300 °C.
