High BET Surface Area Silica Felcosil-300
Physical Properties
This white powder is an ultra-fine silica dioxide, which is produced through a specific manufacturing process. It has unique solubility properties, being soluble in sodium hydroxide and hydrogen fluoride, yet insoluble in other acids, water, and organic solvents. The exact method of synthesis involves advanced techniques such as vapor deposition, chemical vapor reaction, sol-gel method, or other specialized production processes. The resulting powder exhibits high chemical stability and unique interaction with certain chemicals.
