REFRACTORY MATERIALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18181345 titled 'REFRACTORY MATERIALS

The method described in the patent application involves forming a refractory component for a foundry system by creating a preform from a mixture containing a silicon carbide preceramic polymer and either a refractory powder or refractory aggregate. The preform is then heated to pyrolyze the silicon carbide preceramic polymer, resulting in a refractory material with an oxidation-resistant surface suitable for contacting molten metal.

The method includes using a silicon carbide preceramic polymer in the refractory mixture.
The preform is heated to pyrolyze the polymer and form a refractory material.
The resulting refractory material contains either a refractory powder or refractory aggregate in a silicon carbide matrix.
The refractory component has an oxidation-resistant surface for contacting molten metal.

Original Abstract Submitted

A method for forming a refractory component of foundry system includes forming a preform from a refractory mixture. The refractory mixture includes a silicon carbide preceramic polymer and at least one of a refractory powder or refractory aggregate. The method further includes heating the preform to pyrolyze the silicon carbide preceramic polymer and form a refractory material defining the refractory component. The resulting refractory material includes at least one of the refractory powder or the refractory aggregate in a silicon carbide matrix. The refractory component defines an oxidation-resistant surface configured to contact molten metal.
