Silicon carbide ceramic square piece

Silicon carbide ceramic square pieces are advanced ceramic materials made from high-purity silicon carbide (SiC) powder through precision molding, high-temperature sintering, and post-processing techniques.

Caratteristiche principali:
High hardness and wear resistance: The Mohs hardness reaches 9.5, close to diamond, suitable for high friction and high wear environments.
Resistenza alle alte temperature e stabilità termica: It can work stably at 1600 ℃ for a long time, withstand temperatures exceeding 2000 ℃ for a short time, have a low coefficient of thermal expansion, and excellent thermal shock resistance.
Resistenza alla corrosione e stabilità chimica: It has strong resistance to acids, alkalis, molten metals, and organic solvents, and is suitable for harsh chemical environments.
High thermal conductivity and electrical insulation: The thermal conductivity reaches 120-200 W/(m · K), and it also has excellent electrical insulation performance (breakdown voltage>20 kV/mm).
Lightweight and High Strength: The density is only one-third of steel, but the bending strength can reach 400-600 MPa, balancing lightweight and structural strength.
Product form: Standard square piece (with a side length range of 5mm-300mm), adjustable thickness of 0.5mm-50mm, surface accuracy up to Ra0.2 μ m, supporting surface processes such as mirror polishing and matte treatment.

Scenari applicativi principali
Silicon carbide ceramic square pieces provide key solutions in the following fields due to their comprehensive performance:

1. Semiconductor and Electronic Packaging
   Problem solving: Traditional materials such as metals and plastics are prone to deformation, conductivity, or thermal runaway in high temperature or high frequency environments.
   Caso di applicazione:
   Power device heat dissipation substrate: Utilizing high thermal conductivity to quickly dissipate chip heat, improving device efficiency and lifespan.
   Electrostatic Chuck (ESC) components: resistant to plasma corrosion, ensuring the stability of semiconductor etching/deposition processes.
   High frequency communication filter: low dielectric loss characteristics meet the requirements of 5G/6G base stations.
2. Aerospace and energy fields
   Problem solving: Traditional materials fail due to extreme temperatures, mechanical impacts, and chemical corrosion.
   Caso di applicazione:
   Aircraft engine combustion chamber liner: resistant to high temperature oxidation and reduces thermal fatigue cracks.
   Nuclear reactor control rod guide tube: resistant to neutron irradiation and coolant corrosion.
   Fuel cell bipolar plate: low contact resistance and hydrogen permeation resistance improve power generation efficiency.
3. Mechanical seals and wear-resistant components
   Problem solving: Metal sealing rings are prone to wear and leakage, resulting in high maintenance costs for equipment shutdown.
   Caso di applicazione:
   Pump mechanical seal ring: silicon carbide paired with silicon carbide, with a lifespan 5-10 times longer than traditional carbon graphite rings.
   Sand grinder dispersing disc: high hardness reduces medium pollution, suitable for food and pharmaceutical grade grinding.
4. Optics and laser fields
   Problem solving: Ordinary lenses are prone to deformation and decrease in transmittance under high temperature or strong light.
   Caso di applicazione:
   High power laser window: high laser damage resistance threshold, transmittance>95% (visible to mid infrared band).
   Infrared detector substrate: Low thermal expansion coefficient ensures detection accuracy.
