Application area:
Physical and chemical properties of high-purity carbon dioxide gas: One of the carbon oxides, an inorganic substance, non-flammable, usually does not support combustion, and is non-toxic. It is a colorless and odorless gas at room temperature, with a density slightly higher than that of air (1.977g/L, so the upward exhaust method can be used to collect carbon dioxide in the laboratory), soluble in water, and has no flash point. Colorless and odorless.
Uses of high-purity carbon dioxide gas: oxidation, diffusion, chemical vapor deposition, supercritical cleaning gas in semiconductor manufacturing; also widely used in food, aerospace, welding, etc.
