Abstract
The invention discloses a white artificial diamond purifying process. The white artificial diamond purifying process comprises the following steps: adding a mixed solution of hydrochloric acid and nitric acid into a container with a white artificial diamond, heating for boiling, cooling, and washing the white artificial diamond for 5-6 times; then sequentially adding sulfuric acid and nitric acid, heating for boiling, cooling, and washing the white artificial diamond for 5-6 times; then adding hydrofluoric acid, soaking for 8-10 h, and washing the white artificial diamond for 8-10 times. The white artificial diamond purifying process has the beneficial effects as follows: by the white artificial diamond purifying process, a metal wrapper on the outer surface of the white diamond can be effectively removed, the white diamond is higher in transparency and brighter in color, and the quality of the purified white diamond is improved by 80% or above.
Description
Technical field
The invention belongs to artificial diamonds technology field, more particularly to a kind of purifying technique of white rhinestone.
Background technology
Rhinestone is a kind of polycrystalline diamond of the diamond crystalline polymeric by 10 to 30 nanometers of diameter, synthesizing diamond
It is in mainly yellow and yellowish-brown.With rhinestone the aspects such as equipment, technology and technique improvement, white rhinestone at present
Synthetic technology have been achieved with successfully, being widely used in bullion processing industry field.But it is outer after white artificial synthesizing
Table Metal Inclusions are difficult to remove totally, cause significant drawback to white quality of boring, and lead to overall white brill quality decline.
Content of the invention
The purpose of the present invention is that and overcomes above-mentioned deficiency, provides a kind of purifying technique of white rhinestone.
For reaching above-mentioned purpose, the present invention is to implement according to technical scheme below:
A kind of purifying technique of white rhinestone, comprises the following steps:
(1) 1500ml concentration is the hydrochloric acid of 36%-38% and nitric acid mixing that 500ml concentration is 65%-68%, obtains acid solution a；
(2) the white rhinestone after synthesis is put in container, is slowly added to acid solution a, heated and boiled 5-6h, cools down 20min,
Liquid is poured out, white rhinestone pure water is cleaned 5-6 time repeatedly；
(3) sequentially add the sulphuric acid that 150ml concentration is 95%-98% into container, 50ml concentration is the nitric acid of 65%-68%, heating
Boil 1-3h, cool down 20min, liquid is poured out, white rhinestone pure water is cleaned 5-6 time repeatedly；
(4) pour Fluohydric acid. into container into, soak 8-10h, liquid is poured out, white rhinestone pure water is cleaned repeatedly
8-10 time, you can.
Compared with prior art, the invention has the benefit that
The purifying technique of the present invention can effectively remove the white Metal Inclusions boring appearance, makes the transparency of white brill higher, color
More beautiful, after purification, the white quality bored improves more than 80%.
Specific embodiment
With reference to specific embodiment, the invention will be further described, illustrative examples and explanation that here is invented
It is used for explaining the present invention, but not as a limitation of the invention.
