Structure Ceramics  Manufacturers, Traders, Suppliers

Structural Ceramics:
• Zirconia (3Y-TZP/5Y-TZP) - Flexural strength: 800-1500 MPa
• Alumina (96%-99.9%) - Hardness: 15-18 GPa HV
• Silicon Carbide (Reaction-Bonded/Sintered) - Thermal conductivity: 120 W/m·K

‌Alumina Ceramic Components‌
Alumina (Al₂O₃) ceramic parts are widely recognized for their excellent electrical insulation, high mechanical strength, and superior wear resistance. With a typical alumina content ranging from 90% to 99.9%, these components exhibit exceptional thermal stability (up to 1600°C) and chemical inertness, making them ideal for applications in electronics, medical implants, and industrial machinery. Their low dielectric loss and high hardness (Mohs 9) further contribute to their versatility in demanding environments.
‌Zirconia Ceramic Components‌
Zirconia (ZrO₂) ceramics stand out for their remarkable fracture toughness (6-8 MPa·m¹/²) and transformation toughening properties, which exceed those of most engineering ceramics. Stabilized in cubic/tetragonal phases (3Y-TZP/5Y-TZP), they demonstrate exceptional flexural strength (≥1000 MPa) and biocompatibility. These characteristics, combined with low thermal conductivity and wear resistance, make them preferred for dental prosthetics, cutting tools, and thermal barrier coatings in aerospace applications.
‌Silicon Carbide Ceramic Components‌
Silicon carbide (SiC) ceramics offer unparalleled thermal conductivity (120-270 W/m·K) and oxidation resistance at extreme temperatures (up to 1650°C in air). Their unique combination of semiconductor properties, radiation hardness, and corrosion resistance enables applications in nuclear reactors, advanced braking systems, and high-power electronics. With a hardness second only to diamond (Mohs 9.5), SiC components maintain dimensional stability under severe mechanical and thermal loads.

1. Alumina Ceramics (Al₂O₃)
Electronics Industry: Preferred for IC substrates and insulators (CTE 6.5-8.5×10⁻⁶/°C) due to dielectric strength >10 kV/mm
Medical Field: HIP-processed (99.5% purity) components for prosthetics and surgical tools (ISO 6474 compliant)
Industrial Use: Wear-resistant liners in mining equipment (service life 3-5× longer than steel)
2. Zirconia Ceramics (ZrO₂)
Dental Applications: 3Y-TZP crowns with 1200 MPa flexural strength and natural tooth aesthetics
Precision Engineering: Guide rollers in textile machinery (surface roughness 15) to ensure batch consistency across applications.

Engineering ceramics are different from traditional ceramics in terms of raw materials and processes. The specific fine structure makes them have a series of advantages such as high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, insulation, superconductivity, and biocompatibility, and are widely used In the fields of national defense, chemical industry, metallurgy, electronics, machinery, aviation, aerospace, biomedicine, etc.

Engineering ceramics can be divided into oxide ceramics, nitride ceramics, carbide ceramics, boride ceramics, silicide ceramics, fluoride ceramics, and sulfide ceramics according to their chemical composition.

Industrial ceramics are advanced materials made from compounds like alumina, zirconia, silicon carbide, and silicon nitride. These ceramics are valued for their hardness, high-temperature resistance, electrical insulation, and chemical stability.
Industrial ceramics outperform metals and plastics in harsh environments, offering durability and reliability. Despite their brittleness, they are essential for high-precision, high-performance applications in modern manufacturing and technology.
