Silicon nitride ceramics have various applications in the biomedical field, mainly including the following aspects:

Biocompatibility: Silicon nitride ceramics have good biocompatibility and will not cause rejection or immune reactions in human tissues. Therefore, it is often used as a material for medical implants, such as artificial joints, bone repair implants, etc. These implants can bind well with human tissues, reduce postoperative complications, and promote wound healing.

Bioceramics: The chemical stability and corrosion resistance of silicon nitride ceramics make them an ideal choice for bioceramics. Bioceramics are commonly used in the manufacturing of dental restorative materials, dental implants, orthopedic restorative materials, etc., to repair or replace damaged tissues or organs.

Medical devices: The excellent mechanical properties and wear resistance of silicon nitride ceramics make them an important material for manufacturing medical devices. For example, it can be used to manufacture surgical instrument blades, surgical guides, intervertebral disc implants, etc., with good durability and stability.

Biosensors: Silicon nitride ceramics have a wide range of applications in the field of biosensors. Its excellent chemical stability and biocompatibility make it an ideal substrate material for manufacturing biosensors, used for detecting biomarkers, monitoring biological parameters, etc., and has important clinical application value.

Medical imaging: Silicon nitride ceramics have good transparency and X-ray transmittance, making them suitable for manufacturing windows or detectors in medical imaging equipment. It can be used to manufacture X-ray transmission windows, detectors for CT scanners, etc., providing important support for the development of medical imaging.
