Hi! I need to etch silicon out from glass surface and at the moment I have no acces to KOH. Can I use other hydroxides such as NaOH or Ca(OH)2 and expect similar results?
Silicon etchant with hydroxide but without both HF and KOH. ― You may consider: NaOH aq. + (I2, Br2, NaClO3, or Na2Cr2O7·2H2O aq.).
