Compatibility and crystal morphology of cocoa butter substitutes and cocoa butter

In this paper, we restudy the hsianghualite morphology, based on the fact that the right and left forms appear on hsianghualite morphology,it is realized that the right and left forms can not combine each other on a single crystal morphology but can compose a twin.

In this paper,we discussed some classical and basic concepts of crystal morphology(positive and negative forms,right and left forms,general and special forms).

The(influence) of different mineralizer on the morphology of ZnO crystal synthesized by hydrothermal method have been got.

According to the feature of drawing crystal shape from gnomonic projection,a data structure (the single 3 table chain structure )is presented.

Goldschmidt s gnomonic projection,a method of comparison with line and face about the identified visibility of the crystal face on gnomonic plane is given to search hidden line of mineral crystal shape.

The crystal shapes and surface structures of synthetic diamonds have been investigated with SEM.

The significance of crystal form typomorphism of pyrite in assessment of gold deposit;

Data of the crystal form are valuable for describing minerals.

Based on the researches on the crystal form and pyroelectric property of pyrite in Yi Xingzhai Gold Mine,Shanxi province,the typomophies of both crystal form and pyroelectric property of gold-bearing pyrites were set up.

Mechanism of mercury speciation transformation based on combined removal at medium-to-low temperature
