The use of Silicon carbide

1. Carborundum printmaking

Silicon carbide is used in carborundum printmaking – a collagraph printmaking technique. Carborundum grit is applied in a paste to the surface of an aluminium plate. When the paste is dry, ink is applied and trapped in its granular surface, then wiped from the bare areas of the plate. The ink plate is then printed onto paper in a rolling-bed press used for intaglio printmaking. The result is a print of painted marks embossed into the paper.

2. Graphene production

Silicon carbide can be used in the production of graphene because of its chemical properties that promote the epitaxial production of graphene on the surface of SiC nanostructures.

When it comes to its production, silicon is used primarily as a substrate to grow the graphene. But there are actually several methods that can be used to grow the graphene on the silicon carbide. The confinement controlled sublimation (CCS) growth method consists of a SiC chip that is heated under vacuum with graphite. Then the vacuum is released very gradually to control the growth of graphene. This method yields the highest quality graphene layers. But other methods have been reported to yield the same product as well.

Another way of growing graphene would be thermally decomposing SiC at a high temperature within a vacuum. But this method turns out to yield graphene layers that contain smaller grains within the layers. So there have been efforts to improve the quality and yield of graphene. One such method is to perform ex situ graphitization of silicon terminated SiC in an atmosphere consisting of argon. This method has proved to yield layers of graphene with larger domain sizes than the layer that would be attainable via other methods. This new method can be very viable to make higher quality graphene for a multitude of technological applications.

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.

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
