WRIGHT ETCHANT – SILICON AB ETCHANT – GALLIUM ARSENIDE. Wright Etchant reveals crystal dislocations, stacking faults, swirls, striations and slip lines. The etchant is applicable to (100) and (111) crystal orientations, for both p and n type crystals over a wide range of resistivities. Both float zone and Czochralski crystals may be

Also known as ‘waterless’ Kalling’s, this solution reveals the general structure of; Iron + (12–30%) Chromium + (<6%) Nickel (400 Series) Iron + (15–30%)Chromium + (6–40%)Nickel + (<5%) other elements (Series 300) Ni-Cu alloys and Superalloys. Kalling’s No.2 Reagent (AKA Kalling’s etch, waterless Kalling’s) is a metallographic etchant for etching Ni-Cu, nickel-based superalloys, ferritic and martensitic 400 series stainless steels. This etchant will darken martensite, attack ferrite readily and etch austenite slightly. It will not attack carbides.
