AI Technical Summary
Technical Problem
Conventional methods for forming monolithic articles are not cost-effective and have limited scalability, while also failing to achieve improved mechanical strength.
Method used
A method involving extruding a composition of binder, inorganic particles, and graphite particles, followed by drying, debinding at temperatures less than 650 °C, and sintering at temperatures greater than or equal to 650 °C in a low oxygen atmosphere to form a monolithic article with enhanced mechanical strength and electrical conductivity.
Benefits of technology
The method results in a monolithic article with a modulus of rupture of the exterior skin at least 150% greater than that of the core, and the article is electrically conductive, achieving improved mechanical strength and cost-effectiveness.

Abstract
A method of forming a monolithic article includes extruding an extrudable composition to form an extrudate, the extrudable composition including a binder, inorganic particles, and graphite particles, the extrudate including an exterior skin and a core disposed within the exterior skin; drying the extrudate; debinding the extrudate in a debinding atmosphere at one or more debinding temperatures to remove the binder from the extrudate; and sintering the extrudate in a sintering atmosphere at one or more sintering temperatures to remove the graphite particles from the exterior skin of the extrudate and to sinter the inorganic particles of the extrudate, to thereby form the monolithic article. The one or more debinding temperatures are less than 650 °C. The one or more sintering temperatures are greater than or equal to 650 °C and the sintering atmosphere includes an oxygen concentration less than or equal to 2.5%.
