Hi
After a long due, I finally had the time to try smelting a ceramic cat converter.
I crushed then milled the sample cat which weighs 750 grams.
Took a 13.28 gram fine ceramic cat and placed it in a melting dish.
For process I used 168.6825 grams (5.950 oz) lead, which 18.8811 grams (0.666 oz) silver shots were added while it was molten.
The reason oz was used so once this process is finished any traces of PGMs collected by lead silver alloy from the cat can be detected.
I placed the lead-silver alloy on top of fine ceramic cats and melted it, my plan was to melt the lead alloy as it pours down the dish fine cat materials are coming to the surface and during this transition micro sized PGMs are collected.
As lead silver alloy melted at first nothing showed on the surface but few seconds later tiny pieces of fine ceramic cats came to surface of molten lead.
I used a stainless steel rod to stir the fine cat at beneth the molten lead as they came to the surface.
So I poured the molten lead silver into a mold, most of it poured there was a piece left in the dish as fine cats were stuck to it. It can be seen in the following;
This was what was left after I removed the molten lead.
Next I am going to cupel the lead bead, and weig the silver button also dissolve it to see if and what PGMs did it collect from ceramic cats.
Eventuallly I will take the fine to the shop where we will smelt them using our stationary furnaces which is basically working like a large melting dish.
I will also test small sample of this cat smelting with sodium bisulfate as it was briefly discussed by a member.
Best regards
