Type ZK

Type ZK is a relatively-soft, low-viscosity, washcoat-type of Zirconium Oxide (ZrO2) coating that provides very high purity (>99.9% pure) ZrO2 which is usable in vacuum and inert atmospheres to 2000 C (3632 F). This coating should NOT be used in air atmospheres (use Z-Aerosol there). Type ZK gives minimal outgassing, complete by 350 C (662C).


Key Attributes

1. Provides the good properties of ZrO2

  • very low thermal conductivity
  • resistant to reactions with many molten or solid materials
  • low electrical conductivity

2. Applies like house paints,

3. Completely outgassed at low temperature — ideal for mold coating

Ideal Uses

  • Graphite crucibles and molds
  • Anti-stick with diffusion bonding
  • Superplastic forming lubricant
