As the heat treatment temperature increased, the crystallinity of the frustules increased from 9. Applying a ball milling reduced the mean particle sizes of the as-received and nano kırılmaz nedir frustules from

Bioceramic term is used to name ceramics used for the repair and reconstruction of diseased or damaged parts of the skeletal system. This class of materials can be bioinert alumina, zirconia , resorbable tricalcium phosphate , bioactive hydroxyapatite, bioactive glasses, and glass-ceramics , or porous for tissue ingrowth hydroxyapatite-coated metals, alumina. Hip, knees, teeth, tendons, and ligaments replacements and repair for periodontal disease, maxillofacial reconstruction, augmentation and stabilization of the jaw bone, spinal fusion and bone fillers after tumor surgery are some of the application fields. Despite having comparingly low fracture toughness then metallic materials, ceramics are the materials that mimic the bone tissue the best. In last decades patients have become more demanding regarding esthetic and biocompatibility aspects of their dental restorations, ceramic material has become a main object of scientific interest especially from the material point of view. The alumina-zirconia composites are one of the relatively good and promising candidate for biomaterials application, due to biocompatibility and their mechanical properties that combines high flexural strength with a high toughness. Aluminium oxide is one of the most widely used ceramic oxides.

These particles are located on the grain boundaries of the matrix grains, which inhibits abnormal grain growth and enhances the strength of the materials. Human osteoblast cells hOB were plated on samples for 7 days to check the viability of these cells. Alumina and zirconia based bioceramics have found their wide application in the field of load bearing orthopaedics total hip and knee replacement and dental implants. The microscopic observations showed the presence of nano-silica powder, proving an efficient load transfer from matrix to powders on the fracture surfaces, confirming a strong interface between silica powders and matrix. However the long-term use of zirconia in orthopaedics has had controversial results. Applying a ball milling reduced the mean particle sizes of the as-received and heat-treated frustules from Two dimensional graphene plates are thought to provide matrix-reinforcement interface interactions that are not provided by dimensionless nanoparticles and one-dimensional carbon nanotubes CNTs. The prepared nano-silica powders were further used as a filler in an epoxy matrix. For this purpose, a variety of reinforcing nano and submicron particles, such as MgO, SiC, ZrB2, ZrO2 have been incorporated to make alumina based composites. Alumina, zirconia or alumina—zirconia-based composite bioinert ceramics are currently used as femoral heads, acetabular cups for hip replacement, and dental implants. In last decades patients have become more demanding regarding esthetic and biocompatibility aspects of their dental restorations, ceramic material has become a main object of scientific interest especially from the material point of view. Alumina has been widely used in the acetabulum and femur head and articulations digitorum manus.

Zirconium oxide Zr2O is one of the most important components which increases the fracture toughness of alumina. Recently, many studies have been carried out on the use of various carbon sources as reinforcing materials for composites. Alumina is extremely stable in the human body and cannot be dissolved by strong acids or bases. In the recent studies, mechanical and electrical improvements were observed in graphene-doped nanocomposites. Polymeric composites Nanocomposites Materials Diatom frustules Acid leaching.

Despite having comparingly low fracture toughness then metallic materials, ceramics are the materials that mimic the bone tissue the best. Graphene, the elementary structure of graphite, is an atomically thick sheet composed of sp2 carbon atoms arranged in a flat honeycomb structure.
