2013/12/1· Electroless wet chemical etching of bulk powder in HF/HNO 3 solution to produce SiC QDs was first reported in 2007 . On the downside, this process involves extreme conditions such as harsh chemicals (HNO 3 /HF), elevated temperatures (> 100 °C), and/or a high pressure environment  ; all these often coupled to various washing and drying steps.
Silicon carbides for structural use can be classified as: Sintered, bonded by reaction, liquid phase, and sintered solid state. SiC4 bonded by reaction is a compound of a continuous matrix of SiC having silicon from 5 to 20%, and metal that fills the remaining volume.
The beta-SiC with a particulate size range of 30 nm (supplied with Jiuyuan Nano-materials Inc., Sichuan, China) and MWCNT with an average diameter of 50 nm and a length of 1–5 μm (procured from Nanotech Port Inc., Shenzhen, China) were used as the

The β-SiC conversion coatings were successfully synthesized by the SiO(v)-graphite(s) reaction between silica powder and graphite specimen. This paper is to describe the effects on the characteristics of the SiC conversion coatings, fabried according to two different reaction conditions. FE-SEM, FE-TEM microstructural morphologies, XRD patterns, pore size distribution, and

2018/6/15· The SiC grains consist of the primary SiC, which has its origin in the starting SiC powder. The impurities of the primary SiC grains are incorporated into the grains during powder production. The distribution and content of these impurities do not change during infiltration due to the low diffusion coefficients of these elements in the SiC lattice  ,  .
These powders were constituted of nanosized SiC particles homogeneously distributed in the Si3N4 particulate matrix. beta-SiC whiskers were grown at 1400 C in the pores of the matrix. At 1600 °C, the alpha -> beta Si3N4 phase transition took place, but no elemental silicon from Si3N4 decomposition was detected, evidencing the protective effect of the SiC phase
Beta”-alumina is a fast ion conductor material,it was uesd to prepare a new electrolyte for a secondary energy sodium sulfur battery. nanoeta-alumina has the advantages of high activity and small size,which can reduce the synthesis temperature of beta”-alumina.
Beta structured zeolites are widely used for automotive emission control, industrial off-gas purifiion, and reduction of VOC, NOx and N2O. As process alysts, they are ideal for fuel upgrading, production of petrochemical intermediates, and processing chemicals. The zeolites are also suitable for adsorption purposes, such as odor removal and active carbon replacement. Clariant''s
The agglomeration problem of the beta-SiC nanoparticles synthesized by ball milling was resolved to a great extent by the introduction of 2 wt% NH4Cl to the initial Si-C mixture. Under 325 nm excitation, a stable and intensive broad emission peak at 387 nm was observed in the photoluminescence (PL) spectrum of the synthetic nanoparticles, and this emission shows an obvious blueshift of bandgap.
