This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

The effects of ultrasonication and HF washing on SiC nano-particles were analyzed by Zeta potential, particle size distribution and SEM. The stability of suspension of SiC in ethanol, ethanediol and mixture of the two medias with PEG as dispersant at different pH were compared. The optimum ultrasonication time for SiC nano-particles was obtained. The influence of HF washing on SiC nano-particles was discussed; and high stability of SiC nano-particles suspension was achieved at pH=10 in ethanediol with 1wt% PEG as dispersant.
