Understanding the strength and fracture toughness of different ceramic products is crucial for industries seeking durable and reliable materials. In this article, we will explore the exceptional characteristics of strength and fracture toughness exhibited by various industrial ceramic products offered by Vhandy Ceramics.

Alumina Ceramics: Strength and Reliability

Alumina ceramics, renowned for their excellent mechanical strength and reliability, offer a tensile strength of up to 400 MPa and a fracture toughness ranging from 3 to 4 MPa·m^(1/2). These ceramics provide exceptional resistance to wear, corrosion, and thermal shock, making them ideal for applications in industries such as aerospace, automotive, and electronics.

Zirconia Ceramics: Toughness and Durability

Zirconia ceramics possess remarkable toughness and durability, with a fracture toughness ranging from 8 to 14 MPa·m^(1/2). These ceramics exhibit high flexural strength, exceeding 1000 MPa, and exceptional resistance to cracking and wear. With their biocompatibility and low thermal conductivity, zirconia ceramics find extensive use in dental and medical devices, cutting tools, and wear-resistant components.

Silicon Carbide Ceramics: Strength and Hardness

Silicon carbide ceramics are renowned for their exceptional strength and hardness. These ceramics offer a flexural strength of up to 500 MPa and a Vickers hardness of around 2400 to 2800 HV. With their high thermal shock resistance and excellent wear resistance, silicon carbide ceramics find applications in high-temperature furnaces, kilns, and abrasive products.

Boron Nitride Ceramics: Thermal Stability and Strength

Boron nitride ceramics exhibit excellent thermal stability and high strength. With a flexural strength ranging from 100 to 300 MPa, these ceramics provide exceptional electrical insulation and thermal conductivity. Boron nitride ceramics are widely used in the semiconductor, aerospace, and nuclear industries due to their outstanding thermal stability, lubricating properties, and resistance to chemical attack.

Mullite Ceramics: Thermal Shock Resistance and Reliability

Mullite ceramics offer remarkable thermal shock resistance and reliability. These ceramics possess a flexural strength of up to 200 MPa and exhibit low thermal expansion. With their excellent chemical stability and resistance to high temperatures, mullite ceramics find applications in refractory linings, kiln furniture, and thermal insulation components.
