Super Hard Ceramics – They don’t get much tougher | …

Boron Carbide, for instance, is currently the hardest material produced in tonnage quantities and is the third hardest material known to man after diamond and cubic boron nitride. Not far behind it in the hardness stakes comes silicon carbide, more commonly known as carborundum, steeped in history since it was first mass-produced in 1893 and probably the most common of all industrial abrasives.

Silicon carbide, almost as hard as diamond, is used as an abrasive. Tungsten carbide, also very hard, is used for cutting edges of machine tools. Iron carbides are present in …

Silicon Carbide Discovered to be a Key to Developing …

Silicon carbide, which is incredibly hard and heat-resistant, is the key behind optoelectronics. Electroluminescence was first seen in silicon carbide. The material was used in the 1920s for the first LEDs. Silicon carbide LEDs were mass produced in the 1970s

Inspection, Metrology Challenges Grow For SiC

“Silicon carbide is the third hardest compound material on earth with a material hardness of 9.5 on the Mohs scale,” said Meng Lee, director of product marketing at Veeco. “Due to the high hardness and brittleness of SiC, manufacturers are facing cycle time, cost and dicing performance challenges.”

Silicon Carbide: Smaller, Faster, Tougher

Silicon-based devices are so mature and inexpensive to manufacture, it might be hard to believe that any material could shake silicon from its perch. But silicon carbide is quite special.

Hard Choices: Diamond or CBN? | Gear Solutions …

We all look forward to a better, harder-than-diamond, novel synthetic super-hard abrasive such as carbon-nitride (C3N4), which was theoretically proposed by James C. Sung in 1984. Super-hard materials are researched in the same way as manmade diamond, and synthetic CBN was developed by the successful synthesis of light elements such as boron, carbon, and nitrogen.
