The way to show that chromites are as good would be to dig out a half dozen or so of those articles, go through the lists of advantages cited for hex chromates, and challenge them ALL as no longer accurate. I would be interested in hearing from others about their experiences with situations like that in Willits. From what I have been told, this may end up being the biggest yet toxic waste lawsuit. Since the patents are about to issue, our lawyers are allowing us to share our discovery. The coating is formed in an electrolitic bath, replacing the chromate bath in our plating line.
Secondary rinses are reqd to seal the mineral.
The process is similar to the epithermal metasomatism process found in nature. It appears the mineral can tolerate temps. Since the minerals we form are different than what is found in nature the patent office has allowed patents on the minerals and now the process patents are soon going to issue. Two universities, specializing in surface oxides are chacterizing the different minerals. Our approaching method was similar to phos but rather than building a mineral on the surface we modified the existing oxide or sometimes create a uniform oxide and the convert it to a complex oxide.
