Metal Etching and Electroplating A quick guide for SCAdians

Ferric Chloride Ferric chloride is a strongly acidic chemical and gloves, vapour mask and good ventilation are required. Ferric chloride is very effective for etching steel, brass and copper. It can easily be purchased from Dick Smiths for about $10. It etches better when slightly warm and agitated (Use an fish tank air pump system).

Ferric Salt For Hot Sale Factory price

Ferric salts are much better flocculants than ferrous salts, but copperas (FeSO 4), which is oxidized to Fe 2 (SO 4) 3 during aeration or by chlorination may be used, allowing ferric chloride to be produced cheaply by chlorinating a solution of copperas. Iron doses usually vary between 10 and 90 mg Fe 3+ /L.

9.4.3 Iron salts. Ferric ions can be hydrolysed and precipitated as ferric hydroxide at pH >4.5. Poor coagulation occurs in the pH range between 7 and 8.5. The ferric ion (like the aluminium ion) hydrolyses to form hydrates and an acid. Enough alkalinity must be present to combine with the acid and maintain a suitable pH for good coagulation.

Doing so in a semi-sheltered spot out of the wind is a good concept. Being away from inquisitive neighbors or especially children is advisable. Standing upwind is also a good idea. Most of the time small amounts of ferric chloride would be needed so it is not necessary to do the process outdoors. But having adequate ventilation is a must.
