چکیده
In this study, mullite (3Al2O3.2SiO2) and 10 mol % magnesia added zirconia (10 MgO - 90 ZrO2) ceramic powders were synthesized by conventional production processing route. The mixtures prepared mechanical alloying method in acetone environment with ball mill. dried oven at 110 ºC for 24 hours before mixing. Mullite mol% (MgO-ZrO2) reaction sintering from the made up of stoichiometric proportions Al2O3, SiO2, ZrO2 after being homogenized mills. air 1600 oC 3 h 1300 2 h, respectively. Then, phases formed ready to form composites crushing, grinding sieving processes. Then 0 10% weight (M) doped (MgZ) powder metallurgy method. wet milled mill sieved. After drying, compacted preforms 56x12x10 mm uniaxial pressing 200 MPa. green compacts sintered 1500-1600 1-5 conditions using a heating rate 5 min-1 high temperature furnace. microstructure (SEM), phase analysis (XRD), (hardness, 3-point bending wear) physical properties (% shrinkage, water absorption, porosity density) tests performed on composites. whether there is change mixture temperatures effect additive was investigated. data obtained presented graphs tables their comments made.

Mullite-alumina functionally gradient ceramics
Cracks free mullite-alumina Functionally Gradient Ceramics (FGC) have been obtained by sequential slip casting of Mullite-alumina slurries with diserent mullite/alumina ratios. These slurries were prepared with 65 % solids content and viscosities rangingpom 10 to 40 mPa.s. 7he presence of cracks perpendicular to the FGC layers have been attributed to residual stresses developed because of the m...
متن کاملMullite and Mullite/ZrO2-7wt.%Y2O3 Powders for Thermal Spraying of Environmental Barrier Coatings
Mullite and mullite/ZrO2-7wt.%Y2O3 coatings could be thought among the main protective layers for environment barrier coatings (EBCs) to protect Si-based substrates in future gas turbine engines. Considering that feedstock of the compound powder is not commercially available, two powder processing routes Spray Drying (SD) and Flame Spheroidization (FS) were implemented for both types of powders...
متن کاملPorous Composite Materials ZrO2(MgO)-MgO for Osteoimplantology
The pore structure and phase composition of ceramic composite material ZrO2(Mg)-MgO at different sintering temperatures were studied. The main mechanical characteristics of the material were determined and it was shown that they are close to the characteristics of natural bone tissues. It was shown that material structure has a positive effect on the pre-osteoblast cells proliferation. In-vitro...
