Fused Zirconia Parts

Semicorex Ultra-High Temperature Fused Zirconia Parts are specifically engineered for extreme thermal frontiers where conventional refractories fail. By utilizing high-purity Fused Magnesium-Stabilized Zirconia with advanced grain-boundary engineering, these components maintain structural integrity and chemical stability at temperatures reaching up to 2300°C.

Exceptional Performance at 2300°C

Extreme Melting Point: Zirconia (ZrO2) possesses a theoretical melting point of approximately 2715℃, making it one of the few ceramic materials capable of surviving 2300°C environments while maintaining load-bearing capacity.

Enhanced Phase Stabilization: Our proprietary magnesia-stabilization process ensures the material remains in its high-temperature cubic/tetragonal phase, preventing the catastrophic volume expansion that occurs in unstabilized zirconia.

Zero-Contamination Melt: Even at 2300°C, the material exhibits negligible vapor pressure and extreme resistance to chemical reduction, ensuring the highest purity for molten metals or specialized glass.

High-Density Sintering: Each part is processed to achieve near-theoretical density, providing a robust barrier against the penetration of corrosive slags and gases at peak temperatures.

Extreme Heat Applications

These Fused Zirconia Parts are indispensable for "Beyond-Standard" high-heat operations:

Vacuum Induction Melting (VIM): Crucial for crucibles and flow control rings used in the melting of superalloys and refractory metals.

Advanced Aerospace Testing: Used as thermal insulators and structural supports in plasma wind tunnels and rocket engine test stands.

Nuclear Research: Serving as high-temperature shields and containment components in experimental reactor environments.

Ultra-High Temp Furnaces: Ideal for heating element supports and insulation in specialized laboratory and industrial kilns operating above 2000°C.

At these extreme temperatures, the atmosphere (oxidizing, reducing, or vacuum) and the duration of heat exposure are critical. Our engineering team can provide custom-tailored Mg-PSZ or Fully Stabilized Zirconia (FSZ) Fused Zirconia Parts to match your specific furnace atmosphere and cycle requirements.
