Precision Ceramic Zirconia Ceramic Hollow Block Structural Ceramics

Structural ceramics are advanced inorganic, non-metallic materials designed to withstand severe mechanical stress, high temperatures, and corrosive environments. Unlike conventional ceramics, these high-performance materials combine exceptional hardness, thermal stability, and wear resistance—making them indispensable in aerospace, energy, medical, and industrial applications.

Key Characteristics of Structural Ceramics:

1、Ultra-High Mechanical Strength

  Flexural strength up to 1,200 MPa (e.g., Zirconia Ceramic)

  Compressive strength rivaling some metals (2,000–2,500 MPa)

2、Thermal Resilience

  Service temperatures exceeding 1,500°C (e.g., Alumina, Silicon Carbide)

  Low thermal expansion (e.g., Zirconia: 10–11×10⁻⁶/°C)

3、Chemical Inertness

  Resistant to acids, alkalis, and molten metals (e.g., Si₃N₄ in aluminum smelting)

4、Wear & Corrosion Resistance

  Vickers hardness 12–15 GPa (e.g., B4C for armor plating)

Why Choose Structural Ceramics?
They outperform metals and polymers in extreme conditions, offering longer lifespans, reduced maintenance, and energy efficiency. Innovations like nanostructured ceramics are pushing boundaries in 3D-printed components and MEMS devices.

Performance:

1. The strong acid and alkali resistance of zirconia ceramic shall be better than other materials.

2. Zirconia ceramics are not easy to wear, with strong durability. The hardness is close to the natural diamond and light than metals, also has the gem properties such as never wear and non - discoloring.

3. Can maintain the mechanical strength under high temperature, can be used in the condition with high temperature.

4. Good surface finish quality, could get more glossy smooth surface. Small coefficient of wear, with quite good self - lubricating function, non - magnetic, electric insulation, static - free, anti interference and radiation.

Technical Parameters

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
