Contattaci Gas Speciali
Corrosive gases, such as hydrogen bromide, hydrogen chloride, and chlorine are used for etching.
The chlorine and bromine molecules are used because they form volatile products when exposed to metals. High purity is important to avoid corrosion of the gas system as well as to achieve the best process performance.
