Re: Capillary tubes.

... Capillary action is partially responsible for liquid phase sintering of
materials. According to Introduction to Ceramics by Kingery et at., "for
submicron particle sizes, capillaries with diameters in the range of 0.1
to 1 micron develop pressures in the range of 175 to 1750 psi for silicate
liquids and in the range of 975 to 9750 psi for a metal such as liquid

9750 psi is 663 atm or 504 meters of Hg (or 4.2 miles of water) !
Amazing!

P.S. Does anybody know where can such capillary tubes
(diameter ~ 1 micron) can be purchased?
