Description
Yttrium is relatively stable in air but darkens when exposed to light. At temperatures above 400°C, fresh interfaces may ignite. Finely dispersed yttrium is relatively unstable. Yttrium has a low neutron capture cross-section.
It is usually trivalent in its compounds. However, there are cluster compounds in which yttrium can adopt oxidation states <3.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on unbonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
