Abstract
A vacuum insulated glass (VIG) window unit includes an array of spacers provided between at least a pair of substrates, such as glass substrate. Certain example embodiments relate to a VIG window unit including spacers (e.g., pillars) of or including a metal alloy. The metal alloy of the spacer may be an amorphous metal alloy (e.g., Zr and/or Cu based amorphous alloy). Such metal alloy spacers advantageously reduce the thermal conductivity of the spacer array and can increase the center of glass R-value of the VIG window unit.
