Kanthal's new grade of silicon carbide (SiC) expands both the high-temperature performance and application range of the new heating elements. Globar SD element substantial performance improvements are due to advancements in the processing of the recrystallized SiC material. The material is less porous than other SiC materials, and a larger grain structure provides a reduced surface area exposed to the process atmosphere. This reduces the rate of increase in resistance. Designed to replace other existing SiC elements, Globar SD can be supplied as straight rods or multileg elements depending on the application. (www.kanthal.com)
