Developed for demanding applications requiring the combination of thermal conductivity, high wear resistance and boron nitrides corrosion resistance, Grade ZSBN boron nitride is a composite material combining the best thermal performance and machinability characteristics of hot-pressed boron nitride with the strength and non-reactivity of silicon carbide and zirconia.
Grade ZSBN is a uniquely high-performing solid that is especially suited for molten metal applications such as continuous casting breakrings where wear resistance and thermal conductivity are essential.
Chemically – Unparalleled resistance to molten metal wetting due to boron nitride content.
Thermally – Excellent high temperature operation and thermal shock resistance.
Mechanically – Excellent wear resistance and increased strength from zirconia and a small amount of silicon carbide. This feature, unique to ZSBN, results in remarkable corrosion resistance over a wide range of temperatures.
Machinability – Grade ZSBN is easily machined, even to complex shapes and forms, quickly and inexpensively. Machining tolerances of 0.002” or better are achievable.

|Like pure Boron Nitride, the ZSBN crystal structure orients itself during hot pressing. Therefore, many physical properties of CombatⓇ ZSBN are anisotropic and are reported as a function of the orientation of the piece relative to hot pressing (perpendicular or parallel).|
