Ceramic-polymer composites obtained by a cold sintering process

Abstract

Described herein are cold-sintered ceramic polymer composites and processes for making them from inorganic compound starting materials and polymers. The cold sintering process and wide variety of polymers permit the incorporation of diverse polymeric materials into the ceramic.

Description

[0001] Ceramic composite materials and methods [0002] This application claims the benefit of priority to U.S. Provisional Patent Application No. 62 / 379,851 filed August 26, 2016, which is incorporated in its entirety as if fully set forth herein. Background technique [0003] Many ceramics and composites are sintered to reduce porosity and enhance material properties such as strength, electrical conductivity, translucency, and thermal conductivity. The sintering process involves the application of high temperatures, usually above 1,000°C, to densify and improve the properties of the material. However, the use of high sintering temperatures precludes the manufacture of certain types of materials and increases the cost of the materials to be manufactured. [0004] Traditional ceramic component fabrication requires heating and pressing ceramic materials at high temperatures, typically 0.6-0.7 times the melting temperature. Since many non-ceramic materials have lower melting t...
