2015年9月6日 · The normal recommendation is to bite copper plates in ferric chloride in-verted or on edge to avoid precipitated ferric hydroxide clogging the etched line, thus halting etching. However, there is little need for this if the plate is bitten face up' and removed from the solution every 20 min then washed in cold running water to remove the pre ...

2014年12月17日 · I have never used any kind of ferric chloride before, so I don't know much about it. This is labeled as a "ready to use solution," not straight-up ferric chloride. The ingredients listed are iron trichloride, iron dichloride, and hydrochloric acid. The label also says "42 degrees Baumé," which seems to be a measure of density.

2017年3月17日 · Since you have muriatic acid, its really easy to make ferric chloride. All you have to do is add a scrap piece of iron or steel to the muriatic acid (or hydrochloric acid; same thing) and wait for it to dissolve. Then you can either just let the solution be open to air for a few days or add a bit of the hydrogen peroxide and boom, ferric chloride.

2019年1月21日 · Okay question time. I just ordered some Ferric Chloride. I know it's commonly used to etch blades that have been made with Damascus steel patterns. I have a general idea of how it is used and how to use it. But I do not know the exact specifics. I only ordered a little bit a .5 gallon bottle the ...

2008年2月6日 · "Copper plate etching became radically better with the introduction of the Edinburgh etch, which combines anhydrous citric acid powder with ferric chloride. Edinburgh etch cuts etching times by almost one half, and gives a razor-sharp and nearly surgically clean line, all without having to use a vertical etching tank.

2004年7月1日 · To restore the ferric chloride solution’s cutting power repeat the following routine as necessary. It’s a bit fussy, but I got it from a chemist and it is precise science. A. Remove 100 milliliters of ferric chloride solution from the etch tank. B. Add 1 milliliter of HCl acid and shake or stir for 1 to 2 minutes. C.

2011年3月28日 · The ferric nitrate for wood stays in rubber-stoppered glass, as does the straight nitric acid. Both of those are wipe-on application only (for what I do) anyway. I have also done what Dick describes, but instead of sulfuric acid I have descaled with muriatic (HCl) acid and etched with nital (95% ethyl alcohol + 5% HNO 3 by volume) in the pyrex ...

2003年8月19日 · FeCl3 is the chemical structure of ferric chloride. It is produced by placing an iron oxide compound in close proximity to hydrochloric acid, HCl. The resultant chemical reaction yields ferric chloride mixed with water, iron oxide and hydrochloric acid. FeO2 + HCl = FeCl3 + H20 + FeO2 + HCl at eq...
