Vacuum insulated glass units having layered pillars. The glass units include two glass panes and an edge seal between the glass panes with a substantial vacuum gap between them. A plurality of pillars are located between the glass panes as spacers to maintain the vacuum gap. The pillars have a sintered ceramic, alpha alumina, or zirconia body with a tapered sidewall and a functional layer on a surface of the body.
1. A pillar for use in a vacuum insulated glass unit, comprising: a body comprising sintered ceramic, alpha alumina, or zirconia; anda functional layer on at least a portion of the body,wherein the largest dimension of the pillar is equal to or less than 600 microns, and a compressive strength of the pillar is equal to or greater than 400 MPa,wherein the body has a tapered sidewall with a draft angle between 95° and 100°; andwherein the functional layer comprises a compliant planarization layer including a compliant layer polymeric binder comprising silo...
