A friend of mine has an urgent problem and would be pleased 
if somebody could answer at least to one of the following
questions (when I'm wrong in this newsgroup, please let me 
know if there exists a more suited one):

 o) In what way is it possible to produce spherical 
    particles of size 10 micron, made of crystallized
    calcium phospate and/or glass (silica)?
    Maybe also: is it possible to obtain them from
 o) Are there alternative methods to the "sol-gel" resp.
    "spherilizing" process?

Thank you in advance,
U. Winkler
