Silicon carbide is a semiconductor, which can be doped n-type by nitrogen or phosphorus and p-type by beryllium, boron, aluminium, or gallium. Metallic conductivity has been achieved by heavy doping with boron, aluminium or nitrogen.
Superconductivity has been detected in 3C-SiC:Al, 3C-SiC:B and 6H-SiC:B at the same temperature of 1.5 K. A crucial difference is however observed for the magnetic field behavior between aluminium and boron doping: SiC:Al is type-II, same as Si:B. On the contrary, SiC:B is type-I. In attempt to explain this difference, it was noted that Si sites are more important than carbon sites for superconductivity in SiC. Whereas boron substitutes carbon in SiC, Al substitutes Si sites. Therefore, Al and B "see" different environments that might explain different properties of SiC:Al and SiC:B.

In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material. In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.
In 1982 an exceptionally strong composite of aluminium oxide and silicon carbide whiskers was discovered. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced into the market.

Although Moissanite is the hardest substance in nature, it is also very brittle, and it is easy to break when it is hit or crushed by external force. Therefore, when doing sports, heavy physical labor, do not wear Moissanite jewelry, so as not to accidentally collide with hard objects, causing Moissanite to cause permanent and irreparable defects. Below Hmois will introduce you to several maintenance issues.
How to clean
Cold water immersion
Use a small bowl or teacup to soak the Moissanite in water for about 30 minutes, then use a small brush to gently scrub around moissanite Stone, then wave it in the water for a while, then take it out and wipe it with a paper towel.
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.
