Abstract: Provided is a ceramic composite including boron nitride (BN) and titanium diboride (TiB2) for use in 2-D and 3-D heating element applications. The ceramic composite can be used in heater applications without a protective coating. The ceramic composite may be corrosion resistant against oxygen and moisture up to, for example, a temperature of 900° C., and may offer increased corrosion resistance against molten or vapor metal, including aluminum. The ceramic composite may be sufficiently rigid and may not require additional dielectric structural support. The ceramic composite may be sufficiently fracture resistant to enable machining of intricate and complex patterns and designs with a high aspect ratio of the coil length to width or thickness. The ceramic composite may be used with any heater shape, orientation, and size.
