PASTE FOR POLISHING OF JEWELLERY OUT OF NOBLE METALS AND THEIR ALLOYS WITH NON-FERROUS METALS Russian patent published in 2015 - IPC C09G1/02 C09G1/00 

FIELD: metallurgy.

SUBSTANCE: polishing paste includes an abrasive material (an abrasive micropowder based on aluminium hydrate and iron oxide is used as abrasive powder), paraffin, stearine, oleinic acid and asidol. Ratio of said components is as follows, wt %: abrasive material - 65, paraffin - 15, stearine - 10, oleinic acid - 5, asidol - rest.

EFFECT: improved optical attraction of the jewellery out of noble metals and their alloys with non-ferrous metals with simultaneous increasing of the paste polishing ability to Ra 0,02 mcm, and improved ecological situation at the object.
