From what I read, the original Scan Pan was a great item. The ceramic non-stick surface was applied over a titanium base. In effect, the titanium bas was made with microscopic peaks and valleys. The ceramic filled the valleys, creating tiny peaks of titanium that any untensils would ride over, thus protecting the non-stic surface from abuse.
Again, from what I read, the manufacturing process was changed, with the latter being inferior to the original. Suppliers received so many complaints that they refused to service the latter made pans.
The idea is sound enough, but again, when money is the prime motivation for a company, and they let quality slide, we consumers suffer.
All of what I have just written is regurgitation of info I've read in other places. I have no actual experience with the product, so take everything with a grain of salt.
In reference to ceramics in general, there are ceramics that are far tougher than steel. They are expensive and used for special purpose applications. Ceramic piston rings create less wear on an internal combustion engine, and are resistant to heat related problems. Pump bearings made from ceramics are longer lasting than there steel counterparts, are more round, and are immune to corosives.
The problem with ceramics is that they have little or no elasticity, which means that they fail catastrophically when do fail. You can warp a steel pan. You will shatter a ceramic one.
Ceramics are harder, and knives made from them hold an edge forever, but can't be sharpened at home, and are more easily dammaged by shock, i.e. if you drop them accidently on the floor.
I believe Boca, sells knives that are a fusion of ceramics and titanium that give the hardness and superior edge retention of the ceramic blade, but with the added toughness of titanium. That just might be an excellent product. I'd like to test drive such a tool.
Ceramics aren't evil, or substandard for kitchen uses, but you must understand their strengths and limitations.
