Abstract
The invention discloses a preparation method of cyan Karat gold, which comprises the following steps: (1) preparing 15.8 wt% of silver, 4.4 wt% of iron, 2.5 wt% of copper, 1.4 wt% of cadmium, 0.2 wt% of rare earth and the balance of gold, and calculating the weight of each substance according to the weight of the prepared alloy, wherein the rare earth at least comprises one of indium, palladium, rhodium, thorium and holmium; (2) adding a gold block into a crucible, heating to 1100-1200 DEG C to completely melt the gold block; (3) sequentially adding the silver, iron, copper and cadmium according to the formula, finally adding the rare earth, stirring uniformly, and keeping the temperature at 1400-1550 DEG C for 15 minutes; and (4) reversing the mold to form. The method effectively improves the processability of the cyan Karat gold on the premise of ensuring the cyan of the Karat gold, and enhances the ductility of the cyan Karat gold, so that the cyan Karat gold can be processed and applied in more accessories.
Description
Technical field
The present invention relates to the alloy of gold, be specifically related to formula and the making method of cyan k gold.
Background technology
Handsel color is generally formed by yellow, white, rose-colored three kinds of color combination, and quality generally adopts 18K gold (Gold Content is 75%).The color of handsel is formed by gold+repaired mouth really.Repaired mouth is exactly not outer 25% composition contained in 18K handsel.General repaired mouth is K yellow repaired mouth, the white repaired mouth of K or the red repaired mouth of K.18K gold adds that these three kinds of repaired mouths just can form three kinds of colors above.With the ring that handsel is made, that is this ring platinum and gold fusion are made.Because handsel is the jewellery material that European is delithted with always, " happiness,position and longevity " that its implied meaning just finds in emerald with Chinese is the same, represent the hope that people are fine, so handsel jewellery are in the situation steadily risen in the sale of China always, become the ornaments that extremely people praise highly.Handsel ornaments also because its lighter in weight, price are slightly low, technique is exquisite, fashionable, be more and more subject to everybody liking.Cyan karat gold is comparatively rare on the market, and cyan represents honesty, illusion, the positive effect such as salubrious, is the color that youngster likes.
Summary of the invention
The object of the present invention is to provide a kind of be convenient to process the formula of cyan karat gold and preparation method.
The present invention is implemented by following technical measures. a kind of preparation method of cyan karat gold, is characterized in that comprising the following steps:
