METHOD OF PRODUCING BASE PLATES FOR FIRING CERAMIC ARTICLES Russian patent published in 2017 - IPC C04B35/577 C04B35/80 C22C47/08 

Abstract RU 2617133 C1

FIELD: construction.

SUBSTANCE: for producing such plates, the method has been developed for obtaining a two-layer silicon-carbon composite material with different silicon carbide phase content in the layers. The method for producing base plates for firing ceramic articles includes producing the layered preform from carbon felt on the ribbon of carbon and graphite fabric and its siliconization. The siliconization process is carried out by pulling the resulting preform under a capillary feeder supplying silicon melt, followed by crystallization of the melt. The tensile bending strength of the articles at 1250°C reaches 420 MPa.

EFFECT: method provides obtaining articles of large area and relatively small thickness, which can be used in reducing as well as in oxidizing media.
