I take it your research into high-K dielectrics deals a lot with BaTiO3. Have you used 100 nm barium titanate powders with 100 nm strontium zirconate powder for a curie-point shifter? I also found some methods for creating 30-50 nm BaTiO3 powders.
My biggest problem is that my oven will barely hit 1100 C, which is about 80 C too cold for the right firing temperature. Higher temp ovens run much higher price.

Kevin,
"If" ? Sure you can have a piece or two, but...
Gewis,
Your postscript quote is what I was just thinking.
Yes, we have used BaTiO3 as one of our bases, and have used strontium ziconate, but not at 100 nm. We have stayed away from the lead titanates/zirconates, and other toxic materials. We're trying to be as environmentally friendly as possible.
We had a small pottery kiln that went up to cone 10, but we sold it off last year when we shifted gears. We now use a proprietary method to achieve 98% density and much higher temperatures in a fraction of the time.
We've accidentally melted several pure BiTiO3 samples (M.P. 1625 C), which gets messy, because at that temperature it eats right into our equipment. Kind of funny, actually, I was poking around with an early, small slag heap, and that's how we got onto that line of thought in the first place. Good thing I'm accident prone
Our biggest problem was that we were creating large, thin discs, and were running into radial stress cracks vs. warping. Just with any ceramics, the addition of additives vs. desired characteristics (Ke) came into play. In the end, it looked like a design issue to be worked around, though.

"That's funny..." is usually how the best discoveries go. So you're saying that if I turn some good ceramic dielectric into a slag heap, I might come across the secret of RTSCs?Chris Knight wrote:Kevin,

Too bad your methods are proprietary. It'd be interesting to compare proprietary notes some day. Maybe when Trickfox beats us both?

thats interesting
A two directional something, something. Shows you how much I know.
Waiting to hear what more you have to say, thats for sure.
And I agreee with you from another post. I don't think its been built yet either. But if not, when? And by whom? Or are we seeing that happening now? I suspect so, both right in front of us and in other parts of the world, maybe unknown to us.
And I suspect there are many levels between where we are now and to the lady in Hawaii who can shape the rocks in her own hands. Not possible to take the direct route to her level, so learning to build along the way seems rational to me. Many questions to be answered yet.
So Mikado? What is the thing? JDB

Mikado,
Your illustration has elements that remind me of the circuit symbol for a diode. A diode allows current to flow in one direction, but not the other. I therefore guess that this illustration is of Dr Brown’s VERY SPECIAL ‘tunnel’ diode (which should not to be confused with common or garden tunnel diodes readily available in electronic stores).
I also guess that this diode allows information to ‘tunnel’ between the electro-magnetic realm and the electro-gravitic realm, and that the two ‘red triangles’ and the short ‘control line’ indicate that this device is switchable to allows the information to flow in one, the other, or both directions.
I imagine that the device consists mainly of ‘rock’.
I guess that the loudspeaker utilised such a device, as would an identical microphone.
Having said all that, I guess that I’m not very imaginative!
Look forward to seeing what others make of it.
Geoff

Barber pole
OK.... I know this...
It's a barber pole.....
no..... it's a teeter todder....
or maybe it's a maypole with an extra post.
Aww shoot..... it's a FLUX CAPACITOR (no it can't be because it does not have a "y" shape)
Aw shucks I give up
anyhow, I like Geoff's explanation better than mine
Nice to hear from you Geoff.
Can you tell us more about how you understand the tunnel diode thingy

A triode amplifier ?
That's the best idea I've got here...

design
I could turn that into a design for a fabric .... commercially turn it over to some major dressmaker .... have it printed on dresses and sheets and all kinds of other fabric and then turn it loose on the world .... and we would all have something probably pretty important right under our nose.
Oh but wait. Maybe thats already happened. Victoria

Its got sort of a Triac vibe to it. But not exactly. Hmmm

your reaction
I would like to hear your reaction Gregg to the new two chapters just posted. Maybe the most important of the whole book. Take a look .... and then let me know what your thoughts are, please.
And Flow? Mikado? Andrew? Victoria? ( Now I see why you absolutely had to have the first pole position!) Trickfox? Grady? Griffin? Geoff, Gewis? JDB? Linda B?
EVERYBODY ... even if you have never posted your thoughts before. Now is the time! And Elizabeth? Mr. Twigsnapper?
Here we all are and Paul has made it to " THE END" ... whistles and stomps and a big yahoo!!!!!!
And Gregg ....As far as the envelope where you are. My advice?...... Move. MarkC
