Abstract
Official abstract text for this publication.
The present disclosure describes silicon carbide articles useful at high temperatures, and the method of making them. The method includes: providing a plurality of silicon carbide parts; providing a mullite gasket; placing the gasket between the ends of the parts to be joined to thereby form an assembly; applying a load in the range of 15-25 pounds per square inch to the parts' ends distal from the gasket to thereby press the gasket; heating the assembly in a muffle furnace under load to a temperature in the range of 1450° C. to 1550° C.; increasing the load on the to range of 30-50 pounds per square inch and holding the assembly at the temperature for a time in the range of 2-5 days to adhere the mullite gasket to the ends of the silicon carbide parts.
First claim
Opening claim text (preview).
We claim: 1. A method for joining and sealing at least two silicon carbide parts, the method comprising: placing a solid fully dense mullite gasket between and in contact with ends of at least two silicon carbide parts to be joined to thereby form an assembly, wherein said solid fully dense mullite gasket comprises a combined Al 2 O 3 plus SiO 2 content of at least 97 wt. % and 3 wt. % or less of oxide modifiers; and heating the assembly so that the solid fully dense mullite g…
