Preparation and Characterization of CaZrO3 as a Bone Cement

Abstract

The bio ceramic constant of zirconium dioxide and calcium oxide with a weight ratio of 1:1. It was prepared using a ceramic grinder with hardened ceramic balls for 10 continuous hours at a rotational speed of 350 rpm. The resulting powder was then collected and pressed into a mold with a pressing capacity of 5 tons, then sintering process was performed at a temperature of 850^oC for 4 hours the sintering samples of calcium zirconate subjected to milling for 24 hrs to obtain a very fine powder on the at nano scale. Structural examinations of CaZrO₃ powder were carried out by utilizing such as X-ray diffraction and scanning electron microscopy SEM, and Raman spectrum. A mixture of powder was prepared in the form of a paste by adding 30% of polylactic acid PLA for the purpose of making ceramic cement. It can be stored in ampoules for use in treating cracks in bones. The results of the hardness and toughness test of bone cement showed that the percentage of the binding material (polymer) is 30%.
