METHODS OF FORMING SILICON CARBIDE BY SPARK PLASMA SINTERING, METHODS OF FORMING ARTICLES INCLUDING SILICON CARBIDE BY SPARK PLASMA SINTERING, AND RELATED STRUCTURES
A method of forming silicon carbide by spark plasma sintering comprises loading a powder comprising silicon carbide into a die and exposing the powder to a pulsed current to heat the powder at a rate of between about 50° C./min and about 200° C./min to a peak temperature while applying a pressure to the powder. The powder is exposed to the peak temperature for between about 30 seconds and about 5 minutes to form a sintered silicon carbide material and the sintered silicon carbide material is cooled. Related structures and methods are disclosed.
