Standard grades

Grade Description
Globar® SD Elements suitable for most applications in which silicon carbide elements are used. Globar® SD SiC heating elements feature hot zones of recrystallized silicon carbide, optimized for resistance to oxidation and common process gases. Available in rod or multi-leg designs.
Globar® AS A Dense recrystallised SiC material with approximately 20% porosity, a high Weibull modulus, much stronger than SD and our competitors’ products and particularly useful in applications that are cyclical, long span, or subject to strong mechanical vibration.
Globar® HD SiC heating elements designed for the most challenging applications where conventional silicon carbide elements are unsuitable. Globar® HD SiC heating elements feature hot zones of high density, low permeability, reaction-bonded silicon carbide, which is highly resistant to oxidation, and to chemical attack by process volatiles and reactive atmospheres. Available in rod or multi-leg designs.
Globar® SG and SR Tubular spiralled SiC elements made from Globar® HD material.

Lithium-ion battery production

The production of cathode material requires temperatures of around 800 to 1,000 degrees Celsius in the calcination process. Also, the manufacturing process has to be designed and controlled to ensure exceptionally high purity levels in the cathode materials.
