Sorry for the large post, but I wanted people to be able to see the pictures.
Katya's efforts to get an answer regarding the material used in the Aspire Bottom Vertical Coils (written out so it might come up in a search) got me pondering. Then I recalled that Todd (of Todd's Reviews) had taken one apart in a video. When I watched it again it confirmed what I thought I remembered. Here's a link to the full review of the Nautilus mini.

Now here are some screen shots of him taking apart a BVC.
The bottom comes apart like most heads: pin, then rubber gasket with wire through it.
Then he flips it over and we see the top.
Resting on the filler is a thin metal mesh disk. Todd said it
looked like stainless steel.
At this point, Todd laughed and said it looked like a cartomizer.
He then proceeded to pull it out. Do you see fibers? I do.
As he rolled it around in his fingers he commented that he wasn't sure what sort of wicking material could be used to re-wick it, but that cotton might work. Cotton. This gives us an idea of the texture.
Once apart, he again remarked that it is like a carto, but that's not true. The coil in a carto is inside of a "sock" (I seem to recall it's made of silica) and doesn't actually touch the filler.
What got me started on this search was trying to explain to someone that the term "ceramic" isn't specific. There are many types of ceramic, for different applications, made of different materials. Watching Todd's video, it's obvious that the material Aspire is using is a textile of some sort. The results of a search for "Ceramic Textiles" and "Ceramic Cloth" are mostly 3M/Nextel. Seriously, what are the chances a Chinese manufacturer is buying products from 3M?
The results of a search for "Ceramic Cloth China" is worrisome. This is just an example:
China Ceramic Fiber Cloth, Ceramic Fiber Cloth Manufacturers & Suppliers - Made-in-China.com
A sample product description:
The ceramic fiber textile includes Ceramic fiber cloth ,ceramic fiber tape, and ceramic fiber rope are very flexible fabrics, which is processed with ceramic fiber spun bulk, alkali-free glass filament and high-temperature resistant stainless alloy wires through special processing.
Insert material of metal wire and fiberglass filament are incorporated into the yarn
To increase tensile strength of the fabrics both before and after exposure to heat.
Typical applications of cloth ,tapes include gaskets, seals, furnace and welding curtains
Or pipe wrapping.
