METHOD FOR PRODUCING HIGH-TEMPERATURE CERAMIC COATINGS Russian patent published in 1995 - IPC

Abstract RU 2030817 C1

FIELD: semiconductor devices. SUBSTANCE: method involves mixing of YBa2Cu3O7-δ power with organic binder to prepare suspension, application of suspension to substrate using thick-film procedure, drying-out, air calcination, and heat treatment in oxygen environment at 945-950 C. Triethanolamine is used as organic binder; heat treatment in oxygen environment is carried out under the following conditions; heat treatment temperature is raised to maximum value within 2-5 min and then coating is cooled down to room temperature within 1 h + 1 min. EFFECT: improved quality of ceramic coating. 4 tbl
