Anisotropic etching of SiC whiskers.
We have demonstrated a method of producing nanoplatelets or complex well-ordered nanostructures from silicon carbide (SiC) whiskers. Preferential etching of SiC whiskers in a mixture of hydrofluoric and nitric acids (3:1 ratio) at 100 degrees C results in the selective removal of cubic SiC and the formation of complex structures resembling a pagoda architecture. Possible mechanisms governing se...
متن کاملThe Role of Nano Sic Whiskers on the Strength and Density of Aluminum Silicate-SiC-C Compounds as a Reinforced Steel Refractory
This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...
متن کاملEffects of Ferrosilicon Addition and Formation of Insitu SiC Nano-whiskers on MgO-C Refractories
Nowadays, SiC is one of the refractory materials which is used widespread because of its unique properties like structural stability in high temperatures. SiC nano whiskers are important in reinforcement of different kinds of composites like ceramic base materials, thanks to their outstanding mechanical, thermal, and chemical properties like low expansion coefficient, high thermal resistant, hi...
متن کاملElasticity, Stability and Ideal Strength of β-SiC in plane-wave-based ab initio calculations
On the basis of the pseudopotential plane-wave(PP-PW) method and the local-density-functional theory(LDFT), this paper studies energetics, stressstrain relation, stability and ideal strength of β-SiC under various loading modes, where uniform uniaxial extension and tension, biaxial proportional extension are considered along directions [001] and [111]. The lattice constant, elastic constants an...
متن کاملUltrarapid Multimode Microwave Synthesis of Nano/Submicron β-SiC
This paper presents the design, development and realization of a fast and novel process for the synthesis of 3C silicon carbide (β-SiC) nanorods and submicron powder. Using SiO₂ (or Si) and activated carbon (AC), this process allows β-SiC to be synthesized with almost 100% purity in timeframes of seconds or minutes using multimode microwave rotary tube reactors under open-air conditions. The sy...
