Claim Text:
1. A sol-gel method for forming a material layer on a substrate, the method comprising: depositing a layer of a sol-gel material that includes a dispersed solid phase and a solvent onto at least a portion of the substrate to produce a coated substrate, wherein the substrate is exposed to constant humidity and/or solvent vapor pressure during the depositing; evaporating the solvent from the sol-gel material deposited onto the substrate by exposing the deposited layer of sol-gel material to a hot air stream, wherein the evaporating is accomplished in a time ranging from 1 second to 10 seconds under a hot air stream having a temperature of 50° C. to 200° C.; calcining the substrate with the deposited layer of sol-gel material at a temperature of 250° C. to 500° C. for 1 second to 1 hour; and cooling the calcined substrate from the calcining temperature to room-temperature or less in 3 seconds or less by at least one of contacting the coated and calcined substrate with a heat-sink or immersing the coated and calcined substrate in a volume of liquid to yield the material layer on the substrate.
