jewelry beads wholesale los angeles What is artificial vermiculite?

wholesale jewelry turquoise Artificial vermiculite is a kind of silicate mineral, which is the main ore to refine the metallic pupa. Its English name Cubic Zirconia. Referred to as "CZ". Artificial vermiculite vermiculite is widely existed in acidic fires, and is also produced in metamorphic rocks and other sediments. The chemical properties of artificial vermiculite are stable, so gems can also be seen in the rivers' gravel. There are many types of artificial vermiculite, and different artificial vermiculite will have different colors, such as red, yellow, orange, brown, green, or colorless transparency. At present, there are various colors of artificial vermiculite on the market, which are collectively called colorful. The production of colorful pupae is only added to the original raw materials. However, the production of black cubic oxidation is not added to the coloring agent, but it is obtained by heating to 2000C under the real conditions under the real conditions. The main ingredients of vermiculite are silicate, and the chemical molecular formula is ZR [SiO4]. In addition to the main containing tadpoles, it also often contains rare earth elements, 铌, 钽, 钍, etc. The pillar is divided into high -type vermiculite and low -type vermiculite. In the gemstone, the degree of radioactive elements in vermiculite affects the degree of folding, hardness, and density of the radioactive elements. Note that the vermiculite belongs to the square crystal system. In other words, in the face -oriented gemstone, you can see the dual shadow line of face -to -face edges. Now most of the artificial vermiculite (synthetic cubic oxidation) is the
of the so -called " Synthetic cubic oxidation "" is a common artificial vermiculite on the market, also known as "vermiculite", and it is indeed artificial gemstone, but its internal fire is higher than the diamond. , CZ (synthetic vermiculite) is 8.5), a variety of color transformations (synthetic cubic oxidation can synthesize the color -changing effect), the risk of radiation that may occur without natural vermiculite, and the extremely cheap synthetic costs, all make it all make it, all of which are made, all of which are all made. The synthetic cubic oxidation (I am referred to as CZ) has become the preferred material for making popular jewelry (unwavering jewelry). The chemical formula of CZ is "oxidation" instead of the "siliconic acid" of natural vermiculite. Therefore, there is no possible radiation that may appear naturally low, but at the same time, the important attribute of the gemstone is the value preservation effect!
2 Method Edit
First of all, add a stabilizer Y203 in the 2ro2 powder 9: 1, mix well, put in the "round cup" surrounded by the copper pipe, in the upper part of the powder, the upper part of the powder Put a certain amount of metal slices or powder, connect the power, start for 1-2 minutes, and the raw materials begin to melt. Secondly, most of the raw materials are melted. After the requirements are met, the feedback relationship between the high frequency is changed, so that the melt is stabilized for 30-60 minutes. Then the coldness decreased at a rate of 5-15mm/h, and the bottom of the melt began to crystallize due to the reduction of saturated concentrations. As the "cold" continued to decline, the melt will crystallize into crystals. After growing up, slow down the cooling for a while, and then stop heating. Finally, after cooling to the normal temperature, you can take out the product, pat it gently with a small hammer, and the crystal and beautiful cubic oxidative cymbals are presented in front of you.
The above operations from the melting of the powder to the fully melting, the time is faster, and the crystal grows for a long time. Each furnace has a maximum output of up to 120 kg. No melting ingredients and shell materials can be used next time. Add the corresponding color to the raw material when the color is growing.
The technology of the cubic oxidation of the cubic melting shell method was invented by French scientist Roulin and others in 1969, but only exploratory research was given. In 1972, Alexorov and others from the former Soviet Academy of Sciences Liebiev's Institute of Solid Physics improved the French installation, grown up large crystals, and applied for a patent. After 1976, the original Soviet Union pushed the colorless cubic oxidative cymbal crystal as the substitute for diamonds to the market, causing panic in the world's diamond industry, known as the "Soviet diamond". Subsequently, other countries have successively produced this gem and popular internationally.
3 Development process editing
The research on cubic oxidation in my country since 1982. It was put into production in 1983 and quickly occupied the market in the name of "rhinestone", which was welcomed by consumers. The successful synthesis of cubic oxidation has greatly enriched the jewelry market and met people's needs for beauty. However, my country's pigeon blood red, sapphire blue green green cubic oxidation is not yet available in the market.
4 Quality Evaluation Edit
The evaluation of artificial vermiculite is generally carried out from four aspects: color, clarity, cutting, and weight.
1, color
The most popular colors in artificial vermiculite are colorless and blue. Among them, the blue value is the highest, and its color is bright and pure. Colorless vermiculite should not have any impurities, transparent and clear as diamonds. In addition, the pure green and yellow vermiculite looks particularly bright because its refractive index is higher than that of other gems, and it is also loved by people. When evaluating the color, you should also pay attention to the stability of the color to produce color.
2, clarity
Due to the large supply of flawless artificial vermiculite, it also requires high requirements for the internal clarity inside the vermiculite. The evaluation of colorless and blue vermiculite is that the naked eye should not be observed, and pay attention to observing whether the surface ridgeline should be damaged.
3. Cutting
The proportion of cutting: The beautiful artificial vermiculite is largely derived from its high refractive index and high -color scattered. Only at the time of the cutting ratio Show very bright features.
The cutting direction: Because the artificial vermiculite has a high dual refractive index, the significant dual -shadow line will make the sample blur. Therefore, when cutting, the countertop should be strictly vertical, and this direction is also conducive to the most pure blue vermiculite to obtain the purest blue.
4, quality
The colorless and blue vermiculite supplied on the market, from a few points to 10 carats, but it is rare than 10 carats.
