What can I use instead of ferric chloride?

What are some substitutes for alum and ferric chloride? Substitutes include other aluminum and iron salts, like sodium aluminate and ferric sulfate, but these may or may not work. Proprietary products, instead of commodities, may offer a better solution.

How do you make ferric chloride at home?

To the iron add 100mL of water and 100mL of 12M hydrochloric acid. The iron will start reacting with the acid to produce hydrogen gas and ferrous chloride. If the reaction is proceeding too slowly for your liking you can heat up the mixture. A flask of cold water on top is useful to reduce evaporative losses.

How do you etch a PCB without ferric chloride?

Equal parts vinegar and peroxide. A small heap of salt. Your masked copper board/soon-to-be PCB. Optionally, a little heat to speed things up.

How do you make ferric chloride solution from powder?

If you dissolve 500 grams of Ferric Chloride powder in 1 liter of distilled water, this will give you a workable concentrated solution. I usually dilute this solution 4:1 with distilled water for etching steel. When diluting, add the concentrated solution to water slowly, as it also will get hot.

How do I make an etching solution at home?

Mix two-parts of diluted hydrogen peroxide with one-part muriatic acid. There you are, done! The hydrogen peroxide acts as an oxidizer allowing the acid to eat away the copper. Place your board to be etched in your new solution and watch it go!

Make Ferric Chloride (for etching printed circuit boards)

What can you use to etch metal?

For example, steel can be etched with hydrochloric acid, nitric acid, or sulfuric acid. Copper can be etched with ferric chloride mixed in water to form weak hydrochloric acid. Soft aluminum can be etched with ferric chloride, using acrylic polymer paint as a resist.

Is ferric chloride the same as muriatic acid?

Muriatic acid is "hydrochloric acid" (HCl) in a less pure and diluted strength for non-technical applications like cleaning bricks. Ferric Chloride is an iron "salt" of HCl that is nonetheless very acidic, though not as "strong" as HCl. Either will etch any high carbon steel, eventually.

How is ferric chloride made?

Ferric chloride is generally prepared from ferrous chloride through the action of chloride or nitric acid. It is used to make many other ferric compounds and as a chlorinating agent for silver, copper, and some organic compounds.

Is ferric chloride a salt?

Ferric chloride is a deliquescent salt.

Is ferric chloride a basic salt?

Ferric chloride is a salt of strong acid and weak base. So its solution acidic in nature.

Does vinegar etch copper?

Yes, it's also an acid and will react with copper, but slower (it's also much more diluted than ferric or muriatic).

Can you make ferric chloride with muriatic acid?

Making ferric chloride is relatively simple. Here's what you need: Muriatic Acid (Hydrochloric Acid) 0000 Steel Wool.

How do you etch with hydrochloric acid?

What kind of acid do you use to etch a knife?

Etching acids can range from powerful hydrochloric or sulfuric acid to much weaker acids — even household vinegar, citrus fruit, or mustard can be used effectively. In the video linked above, YouTuber TheSmokinApe acid-etches an ESEE blade with French's mustard.

Can you use muriatic acid to etch steel?

Choose the acid you want to etch the steel with.

Possible acids include muriatic (hydrochloric) acid (HCL), nitric acid (HNO3), or sulfuric acid (H2SO4). Certain non-acids that form acid in water, such as ferric chloride (FeCl3) or copper sulfate (CuSO4), can also be used as etching chemicals.

What is ferric chloride used for?

The primary use of ferric chloride is to remove impurities in water and for wastewater treatment. Ferric chloride is also one of the few water treatment chemicals that can sequester odors.

What happens when ferric chloride is added to water?

Ferric Chloride or Iron (III) Chloride (FeCl3) is used as a flocculant in sewage treatment and drinking water production. When small quantities of ferric chloride are added to the raw water, iron(III) hydroxide precipitates and adsorbs finely divided solids and colloids.

Where is ferric chloride found?

Anhydrous iron(III) chloride may be prepared by treating iron with chlorine: 2 Fe + 3 Cl ₂ → 2 FeCl. Solutions of iron(III) chloride are produced industrially both from iron and from ore, in a closed-loop process.

Is ammonia a chloride?

Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. In its naturally occurring mineralogic form, it is known as sal ammoniac.

What is the difference between ferric chloride and ferrous chloride?

Ferrous chloride is produced by reaction of the synthesis hydrochloric acid and ferrous oxide, while ferric chloride is produced by the chlorination of ferrous chloride. Both products are available in the technical or drinking water treatment grade.

What happens when you mix peroxide and muriatic acid?

The hydrochloric acid catalyzes an exothermic decomposition of hydrogen peroxide into oxygen and water. The accumulation of heat and non-condensable gas increases temperature and pressure in this reaction process always lead to runaway reaction and accident owing to inadvertent mixing.

Can you etch a knife with muriatic acid?

The acid etching will need to be done outside or in a well-ventilated area, and you should wear rubber gloves and goggles from here on out. In your well-ventilated area, mix together one part muriatic acid to two parts hydrogen peroxide in a container that's big enough to fit the whole blade.
