Calcium Hydride

Chemistry_R_US - 3-6-2010 at 13:45

Hello. I am in desperate need of calcium hydride, or, barring that, lithium hydride. So I am looking for any one who has a quantity they would like to sell, preferably located in Canada. If I won't be able to get any, I'll have to go the costly and messy route of synthesizing it from the metal or from lime and then a magnesium reduction. Thanks in advance.

Shipping is about $12 for two

Interesting first post , stick around let us know of your results.

Chemical engineer, Volumes 6-8. 1907


The Roessler and Hasslacher Chemical Co. 100 William street, New
York, have a case full of their new peroxide products. "Oxone" is
fused sodium peroxide which upon contact with water produces
320 times its own volume of pure oxygen. "Hydrone" produces
750 times its own volume of hydrogen upon contact with water.
generators of various sizes for use with either "hydrone" or
oxone are shown.

Hydrone was 35% Na - 65% Pb.

Ahhhh I suffer from not understanding — posting a possible
alternative to Ca or Li hydride and the use of psychotropic substances.


However, if you are interested in such in such ... although
perhaps it should go under energetic materials.....

Bacon, A.E. An Experiment with the fruit of the [Acetaea ruba]
Rhodora 5: 77(1903)
In:— Plant Toxicity and Dermatitis: A Manual for Physicians
William & Wilkins 1968


Case History

The following illustrates a non-fatal case of experimental self-intoxication
produced by the ingestion of fruit from the [Actaea ruba]. The onset of symptoms
began within 30 minutes.

"At first there was a most extraordinary pyrotechnic display of blue objects of
all sizes and tints, circular with irregular edges; as one became interested in the
spots a heavy weight was lowered on the top of the head and remained there,
while sharp pains shot through the temples.

&c.

Thanks all for the responses. I'm actually planning on using the hydride for production of negative hydrogen ions in vacuum. (See "Negative hydrogen ion emission from heated metal hydride powder" from Review of Scientific Instruments).

@ Zed, I'm located in Canada.

Franklyn, thanks for the amazing find! Only 13 bucks for 2 pounds of the stuff. I can't see anything that would indicate so, but I'll order some as soon as I find out if they'll charge Hazmat for the shipping (I'm assuming by "about 12 bucks for two" you mean shipping within the states, it's possible it'll be way more out of the country). Anyone here know perhaps?

Never realized that hydrogen gas has hallucinogenic properties.

Don't ask...just order it...it's war surplus radio gear. ;)

Chemistry_R_US - 5-6-2010 at 12:34

Guess I shouldn't give them any ideas, eh :)

No, and it's been sitting quite safely in it's sealed steel container since 1944. Hardly a hazard in shipping. Average size of contents is 1 cubic inch chunks.

franklyn - 6-6-2010 at 11:45

Were actually manufactured in the early 1960's
lot 3500 , Oct 1962 to lot 3750 , Jun 1964
sealed as a can of ham would be complete with
a key to tear the metal can open.

Properly packaged , small quantities of materials
approved for transport are exempt of hazmat fees.

Back in the late 50's on NY City's Radio Row you could buy
gov. surplus H2 generators for weather balloons. They contained
lithium hydride.

Gibson Girl radios were then commonly available.What use they were is a mystery as they operated on a Gov. frequency.

A also remember Fair Radio from the 50's. To bad
R390 Radio Receivers are no longer available. The best
radio ever made... well ... using 60-year old technology.

I may have gotten the older batch...AIR the 60's versions had about 1800g CaH2 Earlier ones were about 750g LiH.
