History - Union Carbide

Union Carbide establishes Carbide and Carbon Chemicals Corporation; also, the first commercial ethylene plant is completed at Clendenin, W. Va. — the start of the petrochemical industry. 1923 Eleven acres of land in South Charleston, W. Va. are leased to set up a commercial scale plant, which will — in a few years — begin production of several ethylene-based chemicals.

Looking at the carbide on the tool, it wasn''t even scratched. The green-wheel on my hand grinder did all 32 cutting blades on my machine and barely showed any wear. If you need to sharpen carbide tools, look at other Silicon Carbide wheels.

OSA | High-quality integrated microdisk resonators in the …

In this Letter, we report, to the best of our knowledge, the first demonstration of high-quality integrated microdisk resonators (MDRs) on a 3C-silicon carbide-on-insulator (SiCOI) platform, working over a wide bandwidth from visible to near-infrared wavelengths. We show record-high quality factors for 3C-silicon carbide (SiC) MDRs of 242,000, 112,000, and 83,000 at the wavelengths of 1550 nm
