Hello have anybody idea what patent this is? It sound like lenr, deuterium stimulated UV?? I find it

I can tell you I use the basic patents and experiment with mostly changing the co-activators from Dy2O3 to various lanthanide and actinides from hydroxides
to oxides to carbonates. I have found my best results in starting with calcium metal in water and then aluminum dust to get to an aluminate. Usually say 99
percent molar strontium or calcium (one or the other) carbonates or oxides (or hydroxides) and 102 percent molar aluminum oxide, with about .05 percent molar
Eu2O3 and around 0.1 percent molar La2O3 (or Co3). Ball mill the hell out of it all, sinter at 900 C for an hour. Ball mill again, then run at 900 C to 1,100
C for an hour with 3 percent H2 and 97 percent N2 at 0.1 liter/minute. The fun is in altering the basic patents in working to find better reds (especially)
and other colors, with glow times of 24 hours from a 20 minute exposure to Uv at I have no idea what intensity the light is.
I am trying many variations on reducing the Eu from three to two, I do not like the H2 idea at all but I am experimenting with designing a tube furnace to
make this safer. I also have 4 pounds of calcium hydride and I was hoping to figure out a way to use this as the reduction and the calcium all at once with
no need to use a gas. Especially since purity is very important (the reason I use ceramic media in my ball mill and even this is not so good). So many
elements act as quenching agents that this is a hard mad science subject to do. Iron for example wipes out all hope of a glow and I don't care how small the
amount of it there is, any at all and you end up in failure. Found this out using steel balls in the mill and studying online as to what was happening. I
don't think ceramic media is so good either but I am not sure what else to use. I even bought a pound of boiling stones and experimented with these as media
for the ball mill.
Right now my main focus is all about playing with different ideas to find the impossibly bright and long lasting red. I hope. One of these days I was going
to write up some of this but I am not far enough along yet and my DSL will not allow me to FTP images to the site anyway. It will appear to log in but
refuses to list no matter what FTP method I use.
I once read about an explosion in a lab making their own aluminates from aluminum dust and calcium metal, I lost the page and never could find it again so I
try to look for it every so often as I really would like to refresh my memory as to what they did so I do not do the same thing by accident. So far I
minimize this possibility by making small amounts at a time and adding the 500 mesh Al in small amounts while hoping I do not end up on the dark side of the
moon. I am mixing this in a beaker with distilled water and Al dust isn't so happy here. Magnetic stir forever, then dry it on low in the kiln, mill, sinter,
and then go on with whatever recipe from there.
There are also experiments not using water to make aluminates but rather sintering the compounds in the kiln after ball milling well, and then going on from
there. Also adding the activator and co-activater before or after this step. Lots of room to play in this area. Like I mentioned my best results were wet
methods starting with pure calcuim and aluminum metals, but also the most dangerous I imagine.
For the most part if you have no metals on the chart around iron (or it's neighbors) and can whip the Eu reduction problem it is harder to NOT make a glow
powder than to make one. What is interesting is these very glow killing elements are the very ones that end you up with high temperature superconducting
ceramics, explain that one to me. I have done a lot of study and experiments (minus the 3 weeks of kiln rebuilding - that ITC 100 works miracles!), and for
whatever reason in this weird mad science ceramic area I keep running into the fact that superconductivity and glow are exactly opposite. At least I think
so, it seems the elements used act this way.
When I have some time I will list what patents I know of so you can read them.
