Molding Features of Silicon Carbide Products by the Method of Hot Slip Casting

The effect of the content of temporary process binder (paraffin, oleic acid, and beeswax) in the range of 10–18% on the molding of the silicon carbide products using hot slip casting has been studied. It has been determined that the flawless compact blanks based on SiC with Y 3 Al 5 O 12 can be prep...

Description
Summary:The effect of the content of temporary process binder (paraffin, oleic acid, and beeswax) in the range of 10–18% on the molding of the silicon carbide products using hot slip casting has been studied. It has been determined that the flawless compact blanks based on SiC with Y 3 Al 5 O 12 can be prepared at the TPB content of 14%. The conditions of four-stage heat treatment of the specimens during removal of TPB have been determined. The bending strength of the ceramic specimens prepared by sintering of the blanks at 1800°C is 437 ± 0.2 MPa.
