Latest Patents

Sung Il Youn holds 2 patents that focus on advanced techniques for preparing ultrahigh-purity silicon carbide powder. His first patent describes a method for preparing an ultrahigh-purity silicon carbide granular powder. This method involves creating a gel where a silicon compound and a carbon compound are uniformly dispersed through a sol-gel process. The process utilizes liquid state silicon compounds and solid or liquid state carbon compounds of varying purities as raw materials. The gel is then pyrolyzed to form a silicon dioxide-carbon composite, which undergoes a two-step carbothermal reduction to yield silicon carbide particles with increased yield.

His second patent relates to porous silicon dioxide-carbon composites and a method for preparing high-purity β-phase silicon carbide granular powders. This method includes preparing a gel with carbon compounds dispersed in silicon dioxide network structures, followed by the creation of porous composites. The process allows for the adjustment of the average particle size, particle size distribution, and purity of the silicon carbide powder through controlled heat treatment.
