Use of our moissanite crystal, rough moissanite
The use of Silicon carbide
1. Jewelry
As a gemstone used in jewelry, silicon carbide is called "synthetic moissanite" or just "moissanite" after the mineral name. Moissanite is similar to diamond in several important respects: it is transparent and hard (9–9.5 on the Mohs scale, compared to 10 for diamond), with a refractive index between 2.65 and 2.69 (compared to 2.42 for diamond). Moissanite is somewhat harder than common cubic zirconia. Unlike diamond, moissanite can be strongly birefringent. For this reason, moissanite jewels are cut along the optic axis of the crystal to minimize birefringent effects. It is lighter (density 3.21 g/cm3 vs. 3.53 g/cm3), and much more resistant to heat than diamond. This results in a stone of higher luster, sharper facets, and good resilience. Loose moissanite stones may be placed directly into wax ring moulds for lost-wax casting, as can diamond, as moissanite remains undamaged by temperatures up to 1,800 °C (3,270 °F). Moissanite has become popular as a diamond substitute, and may be misidentified as diamond, since its thermal conductivity is closer to diamond than any other substitute. Many thermal diamond-testing devices cannot distinguish moissanite from diamond, but the gem is distinct in its birefringence and a very slight green or yellow fluorescence under ultraviolet light. Some moissanite stones also have curved, string-like inclusions, which diamonds never have.

2. Steel production
Silicon carbide, dissolved in a basic oxygen furnace used for making steel, acts as a fuel. The additional energy liberated allows the furnace to process more scrap with the same charge of hot metal. It can also be used to raise tap temperatures and adjust the carbon and silicon content. Silicon carbide is cheaper than a combination of ferrosilicon and carbon, produces cleaner steel and lower emissions due to low levels of trace elements, has a low gas content, and does not lower the temperature of steel.
3. Catalyst support
The natural resistance to oxidation exhibited by silicon carbide, as well as the discovery of new ways to synthesize the cubic β-SiC form, with its larger surface area, has led to significant interest in its use as a heterogeneous catalyst support. This form has already been employed as a catalyst support for the oxidation of hydrocarbons, such as n-butane, to maleic anhydride.

Moissanite Maintenance
How to maintain
Care for the Moissanite ring, do not hit.
Moissanite is the hardest thing in the world after diamonds, but in fact it can't stand the collision. Especially the "claw-set" Moissanite, the waist is very fragile.
Care for the Mosang diamond ring, take good care of it
Professional cleaning: Moissanite stone is very lipophilic and easy to contaminate oil, so apply hand cream and remove Moissanite when washing dishes. It can't be worn while swimming, and the chloride bleach in the water will erode the Moissanitering. Classified Storage: Classify and store different gems to prevent friction between then.
Brand story
Hmois
In 1893, The French Nobel Prize winner Dr. Henry Moissan found these sparkling pieces of Sic.
In 1905, To order Dr. Henri moissan, the newly found gem was named Moissanite
Our company in order to celebrate the Dr. Henry Moissan, So named our brand to Hmois
