Etching Silver : The following recipe seems to work well (taking up to 2 to 4  Sterling Silver - Secret Message Capsule Pendant (secret message can be enclosed forever inside the etched capsule). Esprit del Sol - Etched Southwest Sun 

etching platinum or rhodium, the etching solution has to be heated to attain a reasonable etch rate. Etch-ing of iridium requires strongly heated (boiling) aqua regia. Silver is not attacked by aqua regia due to the formation of a silver chloride passivation fi lm. Chromium,

13 Aug 2012 It was reported that during silicon etching, silver was subjected to have a controversial role. Some researchers debate that silver protects silicon  The pristine silver films prepared without nano-sponge were also fabricated as a comparison. They worked as catalyzer in the following etching process. The  Results 1 - 13 of 13 View our range of products in Etching & Patinas.

Here is the story with our findings, we  29 Oct 2014 Abstract. Copper, silver, and gold share unique properties that offer numerous application possibilities. For instance, low resistivity and high  The process of photo etching silver is just as flexible and accurate as other metal materials. However, because of how silver reacts with chemicals, we use a  .999 fine silver & .925 sterling silver can be etched using a ferric nitrate solution or nitric acid. Both these etchants are more dangerous to use than ferric chloride. Aluminum etchants include hydrofluoric acid, Kellers etch, and homemade solutions made with copper sulfate and sodium bisulfate.

Small plastic container (to etch in, so needs to accommodate whatever size you are etching) Polystyrene (to keep the silver afloat while etching) Bicarbonate of soda (to neutralize the acid afterwards) Your design printed with laser black ink Strong tape (to cover the back of the silver to stop it etching, I used double sided sellotape) I claim 1. In a process for selectively etching thin silver films on a metal oxide substrate to form a pattern which comprises applying a photoresist layer over the silver film, exposing the photoresist to light through a photomask, developing the photoresist to expose a portion of the silver film and etching the exposed film away, the improvement which comprises employing as the etchant a This book is a collection of cleaning and etching solutions extracted from the open technical literature fromabout 1940tothepresent.

This method of etching uses a ferric nitrate solution which also contains nitric acid . This "etchant" is not a pure acid, but etches fine silver and sterling silver (ferric 

925 sterling silver can be etched using a ferric nitrate solution or nitric acid. Both these etchants are more dangerous to use than ferric chloride. Aluminum etchants  You can also dilute the etch with more water if the etch rate is too fast (e.g. in thin film etching). Another etching solution for silver is Iron (III) nitrate in water, heated   I have done some silver etching. It's very different than ferric chloride and a very big step "up". But, the results are very nice and you can get just as clean an  6 Jan 2012 Ferric nitrate (I got crystals from www.megauk.com) Distilled water (from Halfords) Small plastic container (to etch in, so needs to accommodate  How to Oxidize Silver with Egg Yolks.

Acid Etching Metal Jewelry. Part 4a: Etching on Silver Using Ferric Nitrate. Part 1 of this Acid Etching Metal Jewelry series covered how to transfer designs on metal. Part 2 and Part 3 covered how to prepare an acid etch bath for copper and brass. Here in Part 4, the same techniques apply for etching on silver, except the acid is different.

14 Jan 1975 The etching solution useful herein comprises a mixture of ammonia and hydrogen peroxide diluted with methanol. This etching solution dissolves  Previous theories are found inadequate to explain the effects observed in silver, and a theory which regards the surface etching as an approach to equilibrium
