Hi:
Isotopes of an element differ in the number of neutrons. The chemical reactions of an element are governed by the
electrons, which are the same for all isotopes, so chemical means can not be used to separate the isotopes.
There are a number of ways of making the separation, for Uranium see:

It's not clear to me how the isotopes of water are accounted for in it's physical properties. Have these been refined
and defined for each isotope? This may be important since the properties of water show up a lot as the basis for other
definitions.

PS One of the names of the company I worked for was FEI Microwave. There was a rumor that the funder of that company had
a bunch of very special quartz in the vault and that crystals cut from that material had better phase noise than off the
shelf crystals hence he had an advantage over other vendors.

Single isotope diamond is 50% better thermal conductivity of normal diamond.
It has been used in laser optics and thermal transfer applications
(semiconductor heatsinks). I think the highest reported thermal transfer rate
used isotopically pure diamond etched with micro-fluidic channels fed with
coolant. GE makes the diamond material... it was developed as part of
Reagan's Star Wars project.
Isotopically pure silicon has 60% better thermal conductivity than natural
silicon.
Isotopically pure platinum has been used in RTD temperature sensors.
