2009/2/12· The silicon carbide crystal may be eodied as a boule of silicon carbide, where a “boule” may be considered a synthetic formed mass with atomic structure being largely single crystal. The boule may have sufficient thickness so that it can be used to produce freestanding wafers, gemstones or other macroscopic objects.
Lapidary Fundamentals: Cabochon Cutting
They come in silicon carbide or diamond and in grits from 100 to 50,000. In the long run, these belts cost more than wheels with eedded diamond, but the difference isn’t as significant as with the silicon carbide grinding wheels.
Model aggregation: a building-block approach to …
Motivation: Models of regulatory networks become more difficult to construct and understand as they grow in size and complexity. Modelers naturally build large models from smaller components that each represent subsets of reactions within the larger network.
Silicon carbide monoliths are manufactured through extrusion from SiC powder. The pore network is formed during the extrusion process, as a result of the granular geometry of the raw material, although additives may be also used to modify pore characteristics  .

Submersible Pump for Sewage Bypass between Manholes …
The KRSU822 submersible pump features a maximum head of 26.5 m, a maximum capacity of 5.7 m 3 /min, and a compact space-saving design of just 546 mm in diameter. Normally, with engine pumps, it is difficult to suck up fluid from a depth of 7 m or more, but the KRSU822 pump can fit in the deep limited confines of a manhole and there play an active role in draining the manhole.

End-face mechanical seal - Wikipedia
Earlier pump models used mechanical packing (otherwise known as gland packing) to seal the shaft. Since World War II, mechanical seals have replaced packing in many appliions. An end-face mechanical seal uses both rigid and flexible elements that maintain contact at a sealing interface and slide on each other, allowing a rotating element to pass through a sealed case.
Renewable fuel from carbon dioxide with the aid of solar …
When the silicon carbide is heated, the silicon is vaporised, while the carbon atoms remain and re-construct in the form of a graphene layer. The researchers have previously shown that it is possible to place up to four layers of graphene on top of each other in a controlled manner.
Researchers ''iron out'' graphene''s wrinkles
In their new paper, Kim and his colleagues discovered that the layer-resolved graphene transfer irons out the steps and tiny wrinkles in silicon carbide-fabried graphene.

Innovation never stops – Aerospace Manufacturing
Most cutting tools continue to be manufactured from cemented carbide. Over recent years, Iscar has introduced several carbide grades designed specifically for aerospace materials, including IC 5820. The grade coines the advantages of a new submicron substrate, a progressive hard CVD coating, and a post-coating treatment to substantially increase impact strength and heat resistance.
Vertical GaN Devices – the Next Generation of Power …
Silicon carbide (SiC) is another alternative to silicon, but a GaN generally has more attractive fundamental material properties. Current GaN devices are made on hybrid substrates: thin layers of GaN on silicon or silicon carbide creating GaN-on-Si or GaN-on-SiC HEMT (high electron mobility transistor) structures (Figure 3).

To synthesize graphene layers, silicon carbide can be used. When Silicon atoms are sublimated, the left out portion of the silicon carbide becomes a thin graphite surface. These days it has become easy to control the nuer of graphene layers and to get a supreme quality over a large area.

Ceramic - Wikipedia
A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick.The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous (e.g., glasses).
