"Cobalt is a common minor element in meteorites. Phosphides are next to metallic phases important collector of this element. The phase relations within the system Fe-Ni-P and Co-Fe-P are well known. On the contrary the phase relations within the Co-Ni-P and Co-Fe-Ni-P have not been studied yet. The main goals of the project are investigation of phase relations within the ternary Co-Ni-P and quaternary Co-Fe-Ni-P systems and crystal chemical characterisation of phases within these systems. The knowledge of phase relations within these systems and knowledge of crystal chemistry of Co containing phosphides will help to understand the chemistry of meteoritic phosphides. It is be very important information forward understanding the origin of meteorite parent bodies and thus about the development of our Solar System. In addition to that, there are also some implications for material science."@en . .
