Product Description

Zirconia Material Solution for Aerospace & Aero-engine Industry

Core Performance Advantages

This fused zirconia series adopts exclusive fused desilication technology, boasting ultra-high purity with total ZrO₂+HfO₂ up to 99%, while impurities like silicon, iron and titanium are controlled below 0.2% to eliminate casting stains and coating defects, satisfying aerospace zero-defect manufacturing standards.

With a melting point of 2700°C, yttria-stabilized zirconia operates stably at 1200-1600°C with ultra-low thermal conductivity. Its rare-earth composite formula suppresses phase transformation under frequent heating-cooling cycles from engine operation, delivering outstanding thermal shock resistance to avoid coating spalling and component cracking.

Dense fused crystal structure provides strong resistance to molten metal and high-temperature gas erosion, and the material stays chemically inert against molten titanium and high-temperature alloys to prevent mold adhesion and corrosion failure. Customizable spherical spray powder and graded granular raw materials fit all core aerospace manufacturing processes including thermal spraying, investment casting and shot peening.

Comprehensive Competitive Strengths

Independent proprietary production technology realizes localized substitution of imported aerospace-grade zirconia, with products passing strict aerospace performance verification for mass supply to aviation manufacturers and research institutes.

The full product portfolio covers thermal spray yttria zirconia powder, high-purity fused yttria, monoclinic zirconia and ceramic blasting beads; stabilizer proportion, particle size and shape can be customized to match engine thermal coating, titanium casting and surface strengthening requirements.

Large-scale standardized production lines guarantee stable batch delivery, supported by full-process physicochemical testing and complete batch inspection reports, offering shorter lead times and lower overall costs than imported materials.

A professional R&D team provides one-stop technical guidance on coating parameters, casting shell formulation and shot peening processes to resolve typical engineering issues. Confidential customized production service is available for defense and manned space projects.

Key Aerospace & Aero-engine Applications

Aero-engine thermal barrier coatings: Spherical yttria-stabilized zirconia powder forms heat-insulating layers on turbine blades and combustion chambers to resist high-temperature gas corrosion and extend engine service life.
Titanium alloy investment casting: High-purity zirconia serves as shell surface material for fuselage and landing gear components, eliminating oxidation defects and raising casting yield.
Spacecraft supporting parts: High-purity zirconia is used for optical window substrates, while zirconia kiln furniture and thermal coatings support space thermal-end components.
Component surface strengthening: Zirconia blasting beads deburr titanium/aluminum alloy parts and boost surface fatigue strength with heavy-metal-free composition.
Aircraft high-temperature sensors: Yttria-stabilized zirconia electrolyte enables real-time combustion monitoring for aero-engine oxygen sensors.
