Hybrid CO 2 laser-polishing process for improving …

3/1/2020· A novel hybrid polishing process, called laser-assisted polishing (LAP), was proposed in this study for improving the material removal rate (MRR) of polishing silicon carbide (SiC) by coining a CO2 laser source and a conventional polishing machine. The results showed that the MRR increased by 79.0% using the LAP process on the cracked and oxidized SiC sample surface as compared to that …

Our History - Insaco Inc.

At the time, it was the largest volume of flat polished sapphire ever fabried. To handle this new growth opportunity, the company completed a new 12,000 square foot facility in 1962, and changed its name to Insaco. In 1963, Robert S. Haines and his wife were tragically killed in a plane crash. In 1965, David became president of Insaco with

Silicon Carbide - an overview | ScienceDirect Topics

If silicon carbide cannot be polished efficiently at a high precision level, it becomes difficult to use this material in any optical or electrical device. As a nonmechanical or noncontact method of machining, CO 2 lasers can be used to directly machine silicon carbide without needing to worry about tool wear or low removal efficiency [5] .

Silicon Carbide - an overview | ScienceDirect Topics

2875. Silicon-carbide is commercially produced from silica sand (quartz) powder and petroleum coke (CPC)/anthracite coal in required proportion in an electric furnace. Heat at the core of such furnace reaches as high as 2600 °C. A yield of 11.3 ton black silicon carbide is obtained from a furnace charge of 75 ton by this process.
