Alumina Biocompatibility

Journal of Long-Term Effects of Medical Implants, 2018
Alumina (Al2O3) ceramic is widely used for medical devices and its biocompatibility is well known and is reported in articles and textbooks. However, finding proof of this assertion gathered over more than 40 years can be challenging. We performed a literature review about alumina biocompatibility to compile data from the literature.

Ammonia Synthesis Activity of Alumina-Supported Ruthenium Catalyst Enhanced by Alumina Phase Transformation

ACS Catalysis, 2019
The increase of alumina calcination temperature from 800 °C to 1300 °C results in the transformation of γ-Al2O3 to α-Al2O3 phase accompanying a decrease of specific surface area and the amount of tetrahedral Al3+ sites.

Alumina-Alumina and Alumina-Polyethylene Total Hip Prostheses

2004
By the late 1960s, the Charnley hip implant system with a metallic femoral stem and an ultrahigh molecular weight polyethylene (UHMWPE) acetabular component was the primary design for successful total hip arthroplasty (THA). Many of today’s concerns regarding the Charnley system were recognized as early as 1970.
