Determination of the ATZ ceramics with different SiO-=SUB=-2-=/SUB=- contents tensile strength by the "brazilian test" method
نویسندگان
چکیده
The possibility of using the "Brazilian test" method to determination tensile strength sigma t composite zirconia ceramics small-size samples were demonstrated and reliability obtained values confirmed. It was found that dependence alumina toughened (stabilized by calcium oxide) with silica addition (CaO-ATZ + SiO 2 ceramics) on concentration in them has a maximum (sigma_t=450 MPa, at C SiO_2 =5 mol.%). observed is explained an increase transformability tetragonal t-ZrO phase and, accordingly, enhanced role transformation toughening when adding into ATZ ceramics. Keywords: ceramic, strength, test", transformations, toughening.

Synthesis and Characterization of Monodisperse Metallodielectric SiO<sub>2</sub>@Pt@SiO<sub>2</sub> Core–Shell–Shell Particles
Metallodielectric nanostructured core−shell− shell particles are particularly desirable for enabling novel types of optical components, including narrow-band absorbers, narrow-band photodetectors, and thermal emitters, as well as new types of sensors and catalysts. Here, we present a facile approach for the preparation of submicron SiO2@Pt@SiO2 core−shell−shell particles. As shown by transmissi...

A multianvil apparatus ha been used to determine th pressure-temperature mel ing curve of forsterite from 9.7 to 16.5 GPa. At 10.1 GPa a singular point occurs that marks the change from congruent melting at lower pressures to incongruent melting (forsterite periclase + liquid) at higher pressures. The melting curve also passes through two invariant points. At one (15.6 GPa, 2310øC), the phases ...
متن کاملLimitations of Poole–Frenkel Conduction in Bilayer HfO<sub>2</sub>/SiO<sub>2</sub> MOS Devices
The gate leakage current of metal–oxide– semiconductors (MOSs) composed of hafnium oxide (HfO2) exhibits temperature dependence, which is usually attributed to the standard Poole–Frenkel (P–F) transport model. However, the reported magnitudes of the trap barrier height vary significantly. This paper explores the fundamental challenges associated with applying the P–F model to describe transport...
