Query...
I am searching for near perfect glass or metal-glass or low density
metal spheres to be used to measure dense gas viscosity in heated
diamond anvil cells (DACs). The purpose of this study is to address
planetary science (Jovian planet) issues. There are three primary
sphere constraints,
- sphere must have a relatively high density
- sphere diameter range of 20 - 50 microns
- glass transition temperature of glass spheres must be above 300°C
About 4 years ago I attended a talk by a fellow LLNL employee (don't
remember the name) who was manufacturing such spheres for NIF IC
survey experiments/tests. About 10 years ago Exon oil (H. King et
al.) performed similar DAC experiments on very dense fluids. King's
metal spheres are too dense for my proposed application.
I would appreciate any solid leads that you can provide.
Sincerely,
Joe Zaug
