Introduction

Name:Ammonium Sulphate

CAS No.:7783-20-2

Formula:(NH₄)₂SO₄

Apperance:Crystal

Specification

Application

Ammonium sulfate plays a beneficial role in neutral electroplating (electroplating except for strong acid and alkali), such as stabilizing bath solution,refining coating crystallization,and preventing coating brittleness.

1.Auxiliary complexation

Ammonium sulfate actually plays an auxiliary role in the cathodic process as a "bridge" for the smooth deposition of metals.

2.PH buffer

As a result of hydrogen evolution in the cathode process,the pH value of the cathode surface increases continuously. Therefore, pH buffer must be added to all neutral electroplating tanks. These buffers, such as boric acid, acetate and other weak acid and weak base salts, usually complete the buffering function because the ionized H⁺ions migrate to the cathode surface and neutralize the OH^- ions increased due to H₂ evolution, generating water that is difficult to ionize. In addition to completing this function, ammonium sulfate also complexed the free metal M²⁺ion, so as to improve the polarization of the metal ion on the cathode and refine the crystal structure.

3.Conductivity of reactor fluid

Ammonium sulfate has good conductivity. Its addition will effectively expand the application range of cathode current density and improve the dispersion ability of the bath.
