Ferric chloride

Ferric chloride is being used as a mordant for copper and zinc a long time. There are advantages in comparison with etching with nitric acid:

  • it etches more regularly than nitric acid
  • "under etching" is less an issue than with nitric acid
  • less aggressive with makes it more precise
  • safer, no aggressive fumes
  • it is a salt and not an acid.

Disadvantages:

  • it etches slower than nitric acid
  • the liquid is not transparent, you cannot see the etching process visually.

IJzerchloride granulaat (kristallen)
Voor het maken van vloeibare ijzerchloride mengt men 1 gewichtsdeel ijzerchloride met 1 gewichtsdeel water.
Men kan ook de korrels gebruiken om toe te voegen aan bestaande vloeibare ijzerchloride. Gebruik dan de zuurweger om te bepalen of de gewenste concentratie bereikt is.
Let op: Een sterkere concentratie ijzerchloride is niet hetzelfde als een aggressiever etsmiddel. Vaak ets een lagere concentratie ijzerchloride sneller dan een hoge concentratie. Uitproberen dus.

Citric acid is used to accelerate the etching process of copper in ferric chloride. It reduces the formation of deposits in the etched lines.. See "Edinburgh Etch"
