Product Name: Nano Silicon Powder

Description:

Direct current arc plasma evaporation method was used in this paper for the industrial preparation of high purity and highly-dispersed nano-silicon powders and the development its high-tech nano products. The influence of cathode current, filling pressure, pressure ratio of Hydrogen to Argon (PH2/PAr) on the particle size and the yield of nano-silicon powders was studied by orthogonal design method in experiment.

The evaporation mechanism was also discussed in this paper. The results showed that high purity of 99.93 wt% was achieved with near spherical shape and cubic crystal structure. The average particle size of nano-silicon powders produced in the process in this paper ranged from 35 nm to 63 nm with the yield of 9.2 g h−1–175.2 g h−1. The mechanism of silicon powders evaporation was discussed in the paper, which led to the findings of high yield attributed to the co-existence of molecular evaporation and boiling evaporation coexist.

Product Name: Silicon Nanoparticles

Description:

Silicon (Si) Nanoparticles, nanodots or Nanopowder are spherical high surface area metal particles. Nanoscale Silicon Particles are typically 5-25 nanometers (nm) with specific surface area (SSA) in the 30 - 70 m2/g range and also available with an average particle size of 80 -100 nm range with a specific surface area of approximately 5 - 10 m2/g. Thin film deposition of Silicon Nanoparticle quantum dots on the polycrystalline silicon substrate of a photovoltaic (solar) cell increases voltage output as much as 60% by fluorescing the incoming light prior to capture.

Silicon Nanoparticles are also available in ultra high purity and high purity and carbon coated and dispersed forms. They are also available as a dispersion through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers.

Storage Conditions:

Airtight sealed, avoid light, and keep dry at room temperature.

MoSi2 is the intermediate phase of the Mo-Si binary alloy system with the highest content of silica. It has the characters of both metal and ceramic. MoSi2 has good high-temperature oxidation resistance, high-temperature plasticity, heat-conductibility, electro-conductibility, and mobility. And it has a wide range of applications in high-temperature structural ceramics. MoSi₂ is mainly used as a heating element, integrated circuit, high-temperature oxidation resistant coating, and high-temperature structural materials. As a structural material, MoSi₂ can be used in aviation, spaceflight, high-temperature components of automobile gas turbines. Spherical molybdenum disilicide is the core product.

Zirconium Oxide Nanopowder

Stefanic et al. have study the influence of processing parameters (pH value, type of anion, and reaction temperature) on the properties of hydrous zirconia. They mix zirconium n-isopropoxide in isopropanol with aqueous solutions of different pH values and ion types. After that, they calcined the sample at 400°C. They obtain tetragonal zirconia as the dominant phase after calcination.

Stocker & Baiker have prepared zirconia aerogel by sol-gel method using tetra-n-butoxy zirconium (IV) and acid catalysis. They vary the acid to alkoxide ratio and types of alcoholic solvent in the reaction. They found out that zirconia aerogel prepared with an acid-to-alkoxide ratio of 0.95 and butanol have the largest BET surface area (205 m2g-1).

Beena et al. synthesized nanocrystalline zirconia using sol-gel and precipitation techniques. For sol-gel synthesis, they dilute zirconium propoxide to 30wt% by adding propanol and then hydrolyze with dropwise ammonia solution under continuous stirring until pH 10-10.5. For precipitation synthesis, they dissolved zirconium oxychloride in distilled water and then hydrolyzed with dropwise ammonia solution under continuous stirring until pH 10-10.5. The precipitates are then filtered and washed with distilled water to remove chlorine ions. Both sol-gel and precipitate samples are dried in an oven as well as under vacuum in rotavapor before calcined at different temperatures (400-700°C).
