Abstract: Disclosed herein are methods for making a bonded refractory material, the methods comprising preparing a slurry comprising glass precursor particles having an average particle size ranging from about 1 nm to about 200 nm; combining zirconia particles with the slurry to form a batch composition comprising at least about 80% by weight of zirconia; forming a green body from the batch composition; and sintering the green body to form a sintered refractory material. Sintered high-zirconia refractory materials can comprise at least about 80% by weight of zirconia having an average grain size of 100 microns or less, wherein the zirconia is interspersed in a glassy phase, and wherein the sintered refractory materials comprise about 15% or less by weight of the glassy phase. Melting vessels having at least one interior surface comprising such sintered zirconia refractory materials are further disclosed herein.
