Re: Ceramic head ?
There is an article in hackaday, search for "ceramic extruder". The guy who made that piece is sellin them on eBay for somewhere around $50-60. That was found using the same keyword. I've installed one of these, it is working great.

Re: Ceramic head ?
I can see no benefit over peek.
fancy exotic material, but still has a teflon liner, so still can't go over 260 degrees, and will still irretrievably gum up of you accidentally try it.
also, can you remove the nozzle to unblock it? -it doesn't look like you can!
Have I missed a point somewhere?

The nozzle still threads in
At least the whole thing does not melt like peek so you only have to replace a liner
Other than the temp limit it looks like a nice hotend idea.

Re: Ceramic head ?
The above link is where I purchased mine. I personally like it very much, as I had originally bought a hotend similar to the Therminator from some guy who built them in Poland. That style was much too bulky, with a lot of weight on the cylindrical heater block, and I could not get it to fit nicely without cutting a wider groove in the peek. This hotend is very small, lighter and shorter than the stock hotend or even J-heads, and prints nicely. It fits snug on Lawsy's MK-IV, which is also a big plus.

Hi,
I found one on the ebay link above thank you. For me the benefit is only when you gum it, you can put the ceramic part in an oven at 500°C or more and gasify PTFE and ABS, you cannot with PEEK.
Ideally one without PTFE will be better but its difficult to polish a 2 mm inner bore at good price. Exact the hotend coming from Poland is a little bit bulky but well finished.
