For caustic services, namely NaOH, API 682 recommends a particular classifiion of Silicon Carbide known as Sintered Silicon Carbide for both seal faces. This classifiion of Silicon Carbide is “chemically inert in virtually all corrosive environments” due to its manufacturing process (API 682 4thedition, B.2.3.3).
Sintering | definition of sintering by Medical dictionary
The glassy phase was formed by eutectic reaction between [Ta.sub.2][O.sub.5] and Zr[O.sub.2] at the sintering temperature of 1900[degrees]C, because eutectic temperature is less than 1887[degrees]C in the [Ta.sub.2][O.sub.5]-Zr[O.sub.2] system.3) During the sintering process, the compact is heated, usually in a protective atmosphere, at a temperature below the melting point of the main
