Vacuum insulated glass (VIG) window unit including hybrid getter and making same

摘要

This relates to vacuum insulated glass (VIG) window units and methods for making VIG window units. Hybrid getter(s) are utilized. In certain example embodiments, a hybrid getter for use in a VIG window unit and/or a method making same includes both evaporable getter (EG) material and non-evaporable getter (NEG) material. In certain example embodiments, the NEG material may be covered (directly or indirectly) with EG material in the hybrid getter at least prior to getter activating/flashing.

主权项

1. A vacuum insulated glass (VIG) window unit, comprising:
first and second substantially parallel substrates, a plurality of spacers and a seal provided between the first and second substrates, a cavity, at a pressure less than atmospheric pressure, located between the first and second substrates; a container, supported by the first substrate, for holding both non-evaporative getter (NEG) and evaporable getter (EG) material in an overlapping manner, the VIG window unit configured so that after activation of the NEG and EG materials non-evaporative getter (NEG) material is located in the container on the first substrate, and evaporated and deposited getter material from evaporable getter (EG) material is located on the first substrate and also on the second substrate at least in an area substantially opposite the location of the NEG material.
