In this study, usage of gabbro and zeolite in the manufacturing of ceramic products were investigated. Three different compositions which consist of zeolite and gabbro as starting materials were prepared to manufacture a ...

The aim of this study is to examine the effect of MgO and Y2O3 to the carbothermal reduction and nitridation of silica. The synthetic silica, MgO and Y2O3 powders were premixed (4wt% MgO-6% Y2O3, 5% MgO-5% Y2O3 and 6% ...

The MgO-Al2O3-SiO2-TiO2 glass system was prepared by melting method. The crystallization behavior and crystallization kinetics of a sample with glass ceramic composition were examined. DTA and XRD analyses revealed the ...

Hydroxyapatite (HA) is an important material for biomedical implants, because its chemical composition is similar to that of bone tissue. This study focuses on the effect of sintering temperature and the amount of reinforcement ...

In this work, the Woka 5810 powders (88% tungsten carbide-12% cobalt) were used to produce coating by high velocity oxy-fuel spraying. WC-Co is widely used as a tribological coating material providing a combination of high ...
