Property

Moissanite occupies a place in the gemstone world for its unique physical and chemical properties. Its high hardness, strong dispersion, high refractive index and stable chemical properties make moissanite a highly sought after gem material. At the same time, with the continuous progress and improvement of synthetic technology, the quality of moissanite is also constantly improving and optimizing.

Chemical characteristic

1.Chemical composition: The main chemical composition of moissanite is silicon carbide (SiC), which is a compound composed of carbon and silicon elements.

2.Stability: The composition of moissanite is silicon carbide, which is an atomic crystal with strong stability and is not easy to undergo chemical changes. Therefore, in the daily wearing process, Moissanite is not easy to yellow, fade or become blurred, and can maintain its shiny appearance for a long time.

3.No radiation and harmlessness: whether natural moissanite or synthetic moissanite, its essence is silicon carbide, does not contain harmful radiation substances to the human body.

Physical characteristics

1.Color: Moissanite has a wide range of colors, including colorless, blue, green, yellow-green, yellow, etc. Especially since the introduction of the DF grade color synchronized with diamonds in 2015, Moissanite is closer to diamonds in color and difficult to distinguish.

2.Gloss and transparency: Moissanite has the same diamond luster as diamond, and the transparency can vary from transparent to opaque. Most moissanite is transparent colorless or nearly colorless, and some are pale yellow.

3.Refractive index and dispersion: Moissanite has a refractive index of 2.65-2.69, much higher than diamond's 2.42. Its dispersion value of 0.104 is also more than twice that of diamond (0.044), which allows moissanite to exhibit a more intense "fire color" in light, that is, the colorful glow produced when light is reflected and refracted inside the stone.

4.Hardness: Moissanite has a Mohs hardness of 9.25, second only to diamond's 10, and is the second hardest gemstone in nature. This hardness makes moissanite resistant to a certain degree of scratching and wear during wearing.

5.Density and specific gravity: Moiscerite has a density of 3.20-3.24g/cm³, which is about 8.8%-10% lighter than diamond (3.52g/cm³). This difference is reflected in the actual weight of the stone, such as moissanite and diamond of the same diameter, which will be lighter. According to the standard turning of round diamonds, when the diameter is 6.5 mm, the weight of moissanite is about 160 mg, and the weight of diamonds is about 200 mg.

6.Biaxial optical characteristics: Moissanite has biaxial optical characteristics, and the observation of its ghost characteristics depends on the Angle of observation. When viewed from the main facet of the mesa, the ghosting effect is more obvious; When the mesa is perpendicular to the moissanite axis c axis, the ghosting effect will be reduced. This optical feature is completely different from the crown reflection of a single refracted diamond.

7.Fire color: The accurate Moissanite section Angle can maximize the light entering the interior of the moissanite repeatedly refracted and reflected in the interior of the Moissanite without penetrating, in which different wavelengths of light produce different refraction, and finally transmitted from the crown table. In this way, a beam of light entering the interior of the Moissanite becomes dozens or even hundreds of beams of reflected light of different colors, thus making the Moissanite appear bright and colorful.

8.Inclusions: All identified moissanites contain a number of inclusions, which are arranged in parallel needle-like patterns. In some moissanite, thin, parallel rays can be seen. The presence of these inclusions is one of the characteristics formed during the natural or synthetic process of moissanite.

9.Crystal structure: Moissanite belongs to the hexagonal crystal system, which means that its crystal structure has six axes of symmetry. Under laboratory conditions, moissanite can crystallize into 2-3 inch columnar crystals.

Application

Jewelry application

1.Fire and gloss: Moissanite has a higher refractive index and dispersion value than diamond, which allows it to show more intense fire and gloss in light. This unique optical effect makes Moissanite more visually dazzling, becoming the first choice of many jewelry lovers.

2.Color and transparency: Moissanite has a wide range of colors, including champagne, colorless, blue, green, yellow-green, yellow, etc., and most of them are transparent colorless or nearly colorless. This high transparency and rich color selection provides jewelry designers with more creative space to meet the aesthetic needs of different consumers.

Scientific research application

Moissanite has significant value in the field of scientific research, mainly reflected in the following aspects:

1. Materials science research

Composition and structure: The main component of moissanite is silicon carbide (SiC), which plays an important role in materials science. Through the study of moissanite, scientists can deeply understand the physical and chemical properties of silicon carbide and its stability under various conditions, providing a theoretical basis for the development of new materials.

Synthesis technology: The artificial synthesis technology of moissanite continues to improve, providing materials scientists with an experimental platform to study silicon carbide crystal growth, defect control and other problems. These studies help to optimize the synthesis process of moissanite, improve product quality, and promote the application of silicon carbide materials in a wider range of fields.

2. High pressure physics and quantum materials research

In recent years, scientists have used silicon carbide (moissanite) for in-situ magnetic detection of anvils under high pressure. The defect structure such as silicon vacancy color center in silicon carbide has potential application value in quantum information science. This research method provides new ideas and technical means for the research of high pressure physics and quantum materials, and helps to reveal the physical properties and behavior laws of materials under extreme conditions.

Q&A

Q:What are the synthetic methods of moissanite?

A: 1.High temperature and high pressure method (HTHP) : Raw materials such as graphite and silica are put into high temperature and high pressure equipment such as six-sided top press. Under conditions of high temperature (usually more than 2000 °C) and high pressure (usually more than 5 GPa), the raw material is broken down and recombined to form silicon carbide (SiC) crystals. After a period of growth, the required moissanite crystals are obtained. Finally, the crystal is cut into a gemstone shape and polished.

2.Chemical vapor deposition (CVD) : This process uses steam containing carbon and silicon as a raw material. At high temperatures, these vapors are deposited on a special substrate and gradually grow into silicon carbide crystals. Compared with the high temperature and high pressure method, the chemical vapor deposition method can control the crystal growth process and quality more accurately. Similarly, after cutting and polishing, the final Moissanite stone is obtained.
