Steatite is a magnesium silicate material that has been used for many decades as insulators or enclosures for electrical components.  Additionally, it has been incorporated into many appliance, aerospace and automotive applications where moderate strength, low cost and good electrical resistance are required.  Steatite can be formed into complex shapes prior to sintering, which has led to wide usage in a variety of applications.  

In addition to standard steatite, a low loss version of the material is also available.  This material provides the same advantages as our normal steatite, but with a lower dielectric loss factor, typically higher strength and higher density.
