etching solution

Nanometer copper powders were prepared from acidic waste etching solution containing copper using hydrazine hydrate as a reductive agent.

Regular pyramids would form on then-GaN surface. We use KOH solution to be the etching solution of PEC process.

This paper describes analysis adjustment and maintain of persulphate etching solution in PCB production.

In aluminium anodizing process, concentration of NaOH, Al 3 and additives in alkaline etching solution were determined.

Resistant to alkaline etching solution and removal hy alkali.

Etching solution is mixed with 18 wt% hydrochloric acid and saturated oxalic acid.

with the increase of etching solution concentration, the taper length becomes shorter and the surface becomes rougher;

Liquid waste will be etched for regeneration, renewable by the etching solution can be recycled;
