Carbide - Wikipedia

Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.

Rock Tuler Grit and Silicon Carbide Grit Kits

"Rock tuler grit", also known as "rock polishing grit", is a silicon carbide powder that is much harder than the types of rocks that are commonly polished in a rock tuler. If it is tuled in a barrel with rocks and water the abrasion caused by the grit particles rounds the sharp edges off of the rocks.

Smart Transformers Will Make the Grid Cleaner and More

We can now make DC-DC converters out of silicon power electronics that are efficient enough to be used for such microgrids; silicon carbide versions could have higher efficiency and even wider

Production of a high value ceramic material: Silicon carbide

Silicon carbide is often referred to as “carborundum”: this vernacular term commemorates a word coined by Edward G. Acheson in 1892 to describe crystals that he made in an experiment which had the real goal of making a diamond-like crystal from carbon and alundum. Using a primitive furnace of his own design, he in fact made SiC.
