Braggite is a sulfide mineral of platinum, palladium and nickel with chemical formula: (Pt, Pd, Ni)S. It is a dense (specific gravity of 10), steel grey, opaque mineral which crystallizes in the tetragonal crystal system. [3] It is the central member in the platinum …

This father-son team was awarded the 1915 Nobel Prize in Physics, "for their services in the analysis of crystal structure by means of X-rays". This revolutionized crystallography and mineralogy. The mineral braggite was the first new mineral isolated and determined by these x …

Braggite is a mineral with formula of PdPt 3 S 4. The corresponding IMA (International Mineralogical Association) number is IMA2022 s.p.. The IMA symbol is Bg.

A simple twin of braggite (Bg) in association with pyrite (Py), pentlandite (Pn), pyrrhotite (Pyh), and chalcopyrite (Ccp). The host rock is a sulfide-rich PGE-bearing norite. Vertically reflected plane polarized light digital image in air.

Name: To honor Sir William Henry Bragg (1862–1942) and Professor William Lawrence Bragg (1890–1971), Cambridge University, Cambridge, England, pioneers in the X-ray investigation of crystals, as this was the first new mineral to be discovered by X-ray methods alone.

The meaning of BRAGGITE is a mineral PtS consisting of platinum sulfide, usually containing other metals (such as palladium and nickel), and occurring in platiniferous rocks.
