I have a used microwave that I can use for chemistry, in the chemical hood or outside, I was wondering if there are any cautions on using it. Is it
chemical ready? is ventilation sufficient for it not to explode? Any advice on this.

why don't I have permission to view the first link? This is something I am definitely interested in!(sorry to de-rail thread if I did).

I can't see it either, and I searched for it w/o success

I've used a regular household microwave to dry mostly inorganic salts, like acetates, chlorides, oxides and hydroxides with good results. But I drive
off most of the water by heating under a flame or hotplate beforehand. Water-wet calcium hydroxide in the microwave started to catch on fire (!). This
didn't happen if the salt was mostly dehydrated by heating beforehand. Doing that, I've had no problems heating for a few short minutes. I will use it
only if I need something anhydrous.

Microwave Assisted Organic Synthesis (Hardcover)
by Jason P. Tierney (Author), Pelle Lidstrom (Author)
Looks like a good book on the subject. Google will give you a free look-see.

If you happen to be in the UK, someone is offering a nice copy for only Seven Dollars and Eighty Four cents...On Amazon.
Were I there, I would buy it. Me, being in the US., creates an expensive "Postage Barrier".

Has anyone got anything on the dehydration of Calcium Hydroxide to Calcium Oxide in the MW? Now that would be a useful reaction, especially if
lithium, potassium or sodium hydroxide mixtures could be calcined in the mixture. That should give the relevant oxides (as other heating methods are
claimed to do on mixtures of the same with Ca(OH)2 are supposed to achieve), which would be phenomenal in
producing the alkali metal alkoxides - the hydration of the oxides would remove a shitload of water (that produced by the reaction) at the outset.
