In the present study, varying amounts of zirconia (ZrO2)(1, 2, 3 and 5 wt%) was doped with
hydroxyapatite (HA) and their sintering behaviour was evaluated. A simple wet precipitation …

Abstract Zirconia (ZrO2) powder from 1 weight percentage (wt%) to 5 wt% in comparison of
wt% of Hydroxyapatite (HA) was added to form HA-ZrO2 composites to produce HA-ZrO2 …

Zirconia doped Hydroxyapatite (HAP) nanocrystals [Ca10 (PO4) 6− x (ZrO2) x (OH) 2];(0≤
x≤ 1 step 0.2) were synthesized using simple low cost facile method. The crystalline phases …

Hydroxyapatite (HA) is the main mineral component of bone tissue, representing ca. 69 vol%
in bone and up to 98 vol% in dental enamel. Its chemical composition close to the mineral …

One of the reasons of implants failure are the stress forces appearing in the material–tissue
interface due to the differences between their mechanical properties. For this reason, similar …

Homogeneous composite nanopowders of hydroxyapatite/30wt% yttria-stabilized zirconia
(HA–YSZ) containing 0, 3, 5, and 8mol% Y2O3 (namely; HA–0YSZ, HA–3YSZ, HA–5YSZ …

Wollastonite (CaSiO 3) is mainly used for traditional ceramics. In this study, wollastonite-
based ceramics was obtained by solid state reaction. The starting powders were sintered at …

OBJECTIVES: Titanium plates and apatite blocks are commonly used for restoring large
osseous defects in dental and orthopedic surgery. However, several cases of allergies …

The biofunctionalization of metal implants with bioactive ceramics arises as an appealing
strategy for promoting their osseointegration, without impairing implants' good mechanical …

This study aimed to produces and characterize bovine hydroxyapatite (HA) bioceramic with
3Y-TZP addition and analyze different sintering curves. HA was extracted from bovine bones …
