Product Details
Silicon carbide (SiC), also known as carborundum /kɑːrbəˈrʌndəm/, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance.
Wide-scale production
Wide-scale production is credited to Edward Goodrich Acheson in 1890. Acheson was attempting to prepare artificial diamonds when he heated a mixture of clay (aluminium silicate) and powdered coke (carbon) in an iron bowl. He called the blue crystals that formed carborundum, believing it to be a new compound of carbon and aluminium, similar to corundum. In 1893, Ferdinand Henri Moissan discovered the very rare naturally occurring SiC mineral while examining rock samples found in the Canyon Diablo meteorite in Arizona. The mineral was named moissanite in his honor. Moissan also synthesized SiC by several routes, including dissolution of carbon in molten silicon, melting a mixture of calcium carbide and silica, and by reducing silica with carbon in an electric furnace.
Acheson patented the method for making silicon carbide powder on February 28, 1893. Acheson also developed the electric batch furnace by which SiC is still made today and formed the Carborundum Company to manufacture bulk SiC, initially for use as an abrasive. In 1900 the company settled with the Electric Smelting and Aluminum Company when a judge's decision gave "priority broadly" to its founders "for reducing ores and other substances by the incandescent method". It is said that Acheson was trying to dissolve carbon in molten corundum (alumina) and discovered the presence of hard, blue-black crystals which he believed to be a compound of carbon and corundum: hence carborundum. It may be that he named the material "carborundum" by analogy to corundum, which is another very hard substance (9 on the Mohs scale).
The first use of SiC was as an abrasive. This was followed by electronic applications. In the beginning of the 20th century, silicon carbide was used as a detector in the first radios. In 1907 Henry Joseph Round produced the first LED by applying a voltage to a SiC crystal and observing yellow, green and orange emission at the cathode. Those experiments were later repeated by O. V. Losev in the Soviet Union in 1923.

Moissanite Maintenance
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.
The Moissanite ring should be removed when doing heavy work, so as to avoid the deformation of the ring and the Mosang stone.Maintenance Moissanite ring, 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. It is recommended to choose professional jewelry cleaners and instrument cleaning. Maintenance Moissanite Ring, 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
