Abstract

The invention belongs to the field of jewelry and handicraft production, and concretely relates to artificial pink diamond manufactured by inorganic chemical raw material and preparation method thereof. The invention is characterized in that the raw materials of the artificial pink diamond contain all or parts of PbO, ZrO2, SiO2, Na2CO3, CaCO3, Cu powder, magnesium oxide, alumina or aluminium hydroxide, zinc oxide and powdered steatile, and the preparation method contains the following steps: weighing; fragmenting, grinding; mixing, stirring; melting; cutting, polishing and polishing. According to the invention, the artificial pink diamond has brilliant pink color, high refractive index and fire brightness; simultaneously, the melting point is low, and the materials are easy to be molten and processed; simultaneously, the invention has the advantages of high hardness, high-toughness, excellent wear resistance, high temperature resistance, corrosion resistance, weatherability, good performance, stable quality, easy control, etc. The invention has the advantages of low raw material price, simple production technology, low production cost and wide application prospect.

Description

technical field [0001] The invention belongs to the field of jewelry and handicraft production, in particular to an artificial pink diamond produced from inorganic chemical raw materials and a manufacturing method thereof. Background technique [0002] Diamonds are transparent, with excellent fire and dazzling brilliance, and have been loved by people since ancient times. However, natural diamond resources are limited, and the output of colored diamonds (such as pink) is lower, and many consumers prefer pink diamonds, so the price of natural pink diamonds is high, which cannot meet the growing needs of people, so people Synthetic techniques are used to create man-made diamonds, including colored diamonds. [0003] At present, there are already a certain number of artificial diamond products on the market, which are widely used in jewelry, handicrafts, and industrial production. Among them, the artificial diamonds used in jewelry and handicrafts mainly include cubic zirconia...
