In my research and my constant need to try new things out I came across a product called 'High-Tech Ceramic'
It's a material used to make watches and jewelry.
Does anyone know anything about this product, if its available for the public to buy, how to use it etc?
When I google it I only see product info for watches, jewelry etc.

From what I can see its likely some kind of zircon based ceramic--what are you interested in using it for? The term "high tech ceramics" in that context seems to be less a trade name and more a marketing gimmick.
I'm interested in using it for my line of jewelry - always interested in new materials... I see a lot of the big name fashion houses have created bangles rings watches from this material so I'm curious!
So should I start grinding zircons into my cone 6 porcelain ??

I'm looking for something similar, for earrings that won't shatter if you drop them. In my previous life as a jeweler, I came across a material in watches that had a glossy or matte finish that seemed to hold up really well, did not scratch or shatter. I'm in Colorado, and I know that the evil Coors company has a sideline in ceramics, I think they worked on the space shuttle tiles. I haven't found much info, there are some expensive books, like this one on Amazon:An Introduction to the Mechanical Properties of Ceramics
which look interesting, but are very technical. I suspect that some of these materials are made by sintering, compressing and heating powders to form a solid, way beyond our abilities. It does seem likely though, that there may be a way to strengthen clay somewhat. Have you found out anything else?

I believe that during Prohibition, Coors converted breweries into pottery factories.

A few random refs, as you say it looks like they sinter and use some fairly exotic materials.
I suspect that they also use some sort of binder to give the mix green strength before sintering.
There is mention somewhere that the parts are sometimes cast, sintered, and then machined.
This ref appears here from time to time, and gives a low-tech way of achieving tape-casting.
... if you want 1mm porcelain sheets that can be cut and bent.
Look at http://www.keraflex.us/for details of the expensive commercial product.
I assume something similar could be used with a sinter-able body -- if you can find a suitable formulation
and firing schedule.

Ive been working on something similar, and mullite-alumina based ceramics pretty closely approximate the zircona based ceramics except at high temperatures. The trick is to eliminate any free silica with excess alumina and fire it very hot so you end up with the needle form of mullite. Cone 30 is pretty much the minimum unless you want to fire it for days, but once chemical water is gone you can heat it as fast as you like. (Think carbon arc torch blowing directly on it)
