FIELD: chemistry.
SUBSTANCE: invention relates to ceramic composite materials and can be used to make parts and structures for use in machine building, medicine, automotive industry, particularly a composite ceramic-polymer rod for layer-by-layer 3D printing by extrusion of material. Rod contains polyamide 12 in amount of 4.8–10.0 wt.% and aluminium oxide in amount is balance, and it additionally contains paraffin P-2 in amount of 2.7–8.5 wt.%, stearic acid in amount of 1.5–2.5 wt.% and polyvinyl alcohol in amount of 4.53–5.09 wt.%.
EFFECT: technical expansion of operational capabilities of composite ceramic-polymer rod for production of dense sintered ceramic articles, reduced complexity of production of complex-shape ceramic articles, as well as reduced duration of the process of their manufacture.
