Fabrication and microstructure of quartz ceramics with orderly–arranged carbon filler
Heliyon, 2018 Ceramics with tailored pore structure are showing potential applications in some special fields. For fabricating quartz ceramics with orderly–arranged carbon filler, a combination of 3D printing, vacuum suction filtration and sintering was explored to ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Preparation of porous carbides by reactive sintering
工程科学学报, 2015 Three porous carbide ceramics (Cr3C2, TiC and WC) were successfully prepared through a reactive sintering process by reducing their oxides (Cr2O3, TiO2 and WO3) with methane.

Advanced Engineering Materials, EarlyView.A statistical framework is applied to quantify the distribution of electrical resistivity among individual filaments of two commercially available carbon fiber types. Correlations between filament resistivity, tensile modulus, and diameter are examined and complemented by TEM analysis to provide new insight into filament‐level variability relevant for ...

Advanced Engineering Materials, EarlyView.The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Porous ceramic bodies for drug delivery
Journal of Materials Science: Materials in Medicine, 2000 An approach to the production of ceramic drug delivery devices is proposed. Two examples of possible ceramics are dealt with: hydroxyapatite weakly modifiable by living tissue and the bioinert alumina. The possibility to control the formed porosity was taken into consideration for both materials. The ratio between the acquired porosity and the quantity
