Hi, I precipitated Pt and Pd from aqua regia using Ammonium Chloride. I then had PGM powder(32%Pt, 1.5%Au, 1%Pd, 50%Fe, and some base metals). When I burn this powder using a toch, the powder just burns away without forming a button. Also never used Borax. What am I doing wrong?

Hi there,
I'm not sure i understand which powder you tried to burn. Was it the ammonium salts of Pt and Pd? Or the other powder you mentioned (32%Pt, 1.5%Au, 1%Pd, 50%Fe, and some base metals)?
