Synopsis. Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." Some reagents are just a single element. However, most processes require reagents made of chemical compounds.Some of the most common ones are listed below. Composition of concentrated reagent grade acids, ammonium hydroxide, and sodium and potassium hydroxide solutions (with dilution directions to prepare 1N solution) Chemical Name: Molecular Formula: Approx.

Kallings 2 reagent composition




However, short-range diffusion in the layered structure zones led to different chemical composition among different phases (δ, γ and σ), such that the electrical potential of each phase is different. Therefore, it is easy to etch the layered structure in 310S-WM after PWHTs using relatively weak acid (Kalling’s reagent).

Electrolytic 5 to 7 amps The microstructural features were revealed by Kalling's reagent number 2 (100 ml HCl -100 ml ethanol -5 g CuCl 2 ) as the standard chemical etchant for nickel-based superalloys [25, 26].
