What are Structural Ceramics? How much do you know about its features?

Have you ever wondered why a ceramic backplate in a smartphone is not only aesthetically pleasing, but also provides excellent resistance to abrasion and scratches? How do high-temperature structural ceramic materials in automobile engines improve performance and efficiency? Why are medical devices and ceramic surgical implants favored to help improve the patient experience?

What kind of power is behind these seemingly ordinary ceramic materials? Today, Supreme Ceramic Materials Co., Ltd. will take you through what "Structural Ceramics" is.

1. Definition of structural ceramics

Structural ceramics, also known as engineering ceramics or high-temperature structural ceramics, are advanced ceramic materials used in high-temperature, high-stress and corrosive environments. They have excellent mechanical properties, high temperature resistance, corrosion resistance, wear resistance and other characteristics, and can be used under harsh working conditions that are difficult for metal materials and polymer materials. Therefore, structural ceramics play a key role in promoting the development of certain emerging technologies, and show broad application prospects and potential economic and social benefits in the fields of electronic engineering, energy, machinery, automotive, metallurgy, chemical industry, biology and medicine.

Second, what are the structural ceramics

1. Classification according to structural ceramic materials

(1) Oxide ceramics: such as alumina, yttrium oxide, zirconia, mullite, toughened zirconia, zircon, aluminum titanate, etc.;

(2) Nitride ceramics: such as aluminum nitride, silicon nitride, boron nitride, Sialon, etc.;

(3) Carbide ceramics: such as silicon carbide, titanium carbide, boron carbide, etc.:

(4) Boride ceramics: such as titanium boride, zirconium boride, etc.

2. Classification according to the field of use of structural ceramics

(1) Electronic ceramics: electronic structural ceramic materials are valued for their excellent electrical insulation and thermal conductivity, and are widely used in electronic components, sensors and power devices.

(2) Mechanical ceramics: Mechanical ceramics are widely used in various mechanical components such as mechanical ceramic seals, cutting tools, bearings, gears, etc., mainly due to their high wear resistance and high hardness characteristics.

(3) Engine ceramics: Thermal insulation engines made of ceramic materials are widely used in gas turbine blades, piston tops and inserts and other components due to their heat resistance, damage resistance, high strength, high toughness, light weight and excellent thermal insulation performance.

(4) Chemical ceramics: The corrosion resistance of ceramics makes them ideal for smelting crucibles, heat exchangers and various corrosion-resistant parts of non-ferrous metals and rare metals.

(5) Bioceramics: Bioceramics are often used in the medical field due to their excellent biostability and compatibility, such as: bone repair and regeneration, orthopedic implants and dental restoration materials.

3. Characteristics of structural ceramics

1. High temperature resistance: With high melting point and extremely low expansion coefficient, structural ceramics can still maintain stable physical and chemical properties in high-temperature environments, or can withstand sudden temperature changes without deformation or rupture in the case of quenching and hot and cold occasions, ensuring the durability and reliability of ceramic materials under high-temperature operation.

2. High strength and hardness: The compressive strength and hardness of structural ceramics are impressive because of their dense crystal structure, which can easily cope with the challenges of high mechanical stress.

3. Corrosion resistance: Structural ceramics, such as silicon nitride and alumina, exhibit good corrosion resistance to most chemicals due to their inherent chemical stability and non-metallic properties, and are suitable for harsh environments such as chemical smelting.

4. Electrical insulation: The electrical insulation of structural ceramics can effectively block the flow of current, coupled with its low dielectric constant, it further enhances the ability to prevent current leakage and short circuit, and becomes an ideal choice in the field of insulators, precision electronic components and high-voltage equipment, ensuring the safe and stable operation of the electrical system.

5. Abrasion resistance: Structural ceramics have high surface hardness and good wear resistance, which is suitable for use in working environments with severe abrasion, such as cutting tools and abrasives.
