  • Process for producing non-porous coating for corundum substrates
    Patent number: 4004052
    Abstract: A process for producing a non-porous coating for corundum substrates with a corundum content of 90 to 100% the process comprises applying a barium, calcium or strontium alumosilicate glaze to the substrate, followed by heat treatment of the substrate at a temperature within a range of from 1,350 to 1,650.degree.C at a heating rate of from 100.degree. to 500.degree. C per hour, and thereafter cooling at a rate of about 150.degree. C per hour, thus giving a glass-ceramic coating on the substrate. The process is useful, mainly, for producing integral circuits and other micro-circuits and precision resistors.
