I need values for compressive strength, modulus of elasticity, crack resistance, flexural strength and porosity, two of the most common calcium phosphate materials. What sources have it?
Hydroxyapatite is a calcium phosphate mineral that is commonly used in biomedical applications due to its biocompatibility and similarity to the mineral component of bone. The mechanical properties of hydroxyapatite can vary depending on factors such as the synthesis method, porosity, and microstructure of the material. Some values for the mechanical properties of hydroxyapatite are provided below:
- Compressive strength: 100-300 MPa
- Modulus of elasticity: 50-120 GPa
- Flexural strength: 50-100 MPa
- Crack resistance: 2-4 MPa*m^0.5
- Porosity: 30-80%
These values can vary depending on the specific formulation, processing conditions, and testing methods used. It is important to note that hydroxyapatite is often used in combination with other materials, such as polymers or metals, to improve its mechanical properties and functionality in biomedical applications.
There are several sources where you can find information on the mechanical properties of hydroxyapatite and other calcium phosphate materials, including scientific literature, textbooks, and online databases. Some examples of resources that may be helpful include:
- The Handbook of Bioceramics and Biocomposites by Iulian Vasile Antoniac and Ipek Akin
- The Journal of Biomedical Materials Research Part B: Applied Biomaterials
- The Journal of Materials Science: Materials in Medicine
- The Materials Project database (materialsproject.org)
- The Open Materials Science Journal
You can search these resources using keywords such as "hydroxyapatite mechanical properties," "calcium phosphate biomaterials," or specific properties such as "compressive strength" or "modulus of elasticity."
