As the European Union tries to reduce its dependence on Russian energy, the Russian president recently said Russia would try to shift its energy exports to the east, adding that there was no way for European countries to give up Russian gas immediately.

Russia supplies about 40 percent of the EU's gas, and western sanctions imposed over the conflict with Ukraine have complicated financing and logistical arrangements for existing agreements, hitting Russian energy exports, the report noted.  

Russia has been building closer ties with China and other Asian countries as the European Union debates whether to impose sanctions on Russian gas and oil and member states seek supplies from elsewhere, Reuters said.  

"So-called partners from unfriendly countries admit that they cannot survive without Russian energy, including gas," the Russian president said in a televised government meeting. There is no reasonable alternative to Russian gas in Europe right now."  

He also said Europe was driving up energy prices and destabilizing markets by talking about cutting off Russia's energy supplies. Russia, which produces about a tenth of the world's oil and a fifth of its natural gas, will need new infrastructure to increase energy supplies to Asia, he said.

He ordered Moscow to submit a plan by June 1, including "the expansion of transport infrastructure to countries in Africa, Latin America, and the Asia-Pacific region".  

He also sought to clarify the possibility of integrating two pipelines -- the Sakhalin-Khabarovsk-Vladivostok gas pipeline in the Far East and the "Power of Siberia" gas pipeline to China -- into Russia's unified gas supply system. In theory, connecting these routes to larger gas networks could allow Russia to divert gas from Europe to Asia.

Because of the ever-changing international situation, the supply and prices of international bulk Nano silicon powder ,Nano silica fume overview,Application of nano silicon powder,Nano silica powder price,Nano silica powder supplier are still very uncertain.

Nano silica fume overview

Nano silicon powder is a new generation of wide bandgap energy semiconductor optoelectronic semiconductor material, and it is also a high-power light source material.Silicon nanoparticles (SiNPs) are biocompatible, metal-free quantum dots with size- and surface-customizable photoluminescence. Silicon nanoparticles consist of pure amorphous nano-silica. The particle size is less than 5 nanometers, and the particle size range is narrow. 

Silicon nanoparticles are known to be absorbent and abrasive, and mesoporous silicon nanoparticles have important applications in drug delivery and nanomedicine. In the past decades, silicon nanoparticles have attracted great attention due to their interesting physical properties, active surface states, unique photoluminescence, and biocompatibility. 

Physical and chemical properties of nano-silica powder

Nano silicon powder has the characteristics of high purity, small particle size, uniform distribution, large specific surface area, high surface activity and low bulk density. It is non-toxic, odorless and has good activity. Nano-silicon powder is a new generation of optoelectronic semiconductor materials, with a wider band gap energy semiconductor, and is also a high-power light source material.

The preparation methods of nano-silicon powder include mechanical ball milling, chemical vapor deposition, and plasma evaporation and condensation. The industrial production of nano-silica fume in western countries started early, and there are specialized silicon powder product companies, such as Japan Chemicalbook, American DuPont, Germany HCStark, Canada Tekner and so on. Using the condensation method to produce a variety of high-purity nano-silica powders with different particle sizes, it is in a leading position in the world in production technology.

Application of nano silicon powder

1. Nano-silicon wires that can be used to make nano-silicon-carbon anode materials for rechargeable lithium batteries, or coating graphite on the surface of nano-spherical silicon powders as silicon-carbon anode materials for rechargeable lithium batteries. It can increase the capacity and the number of charge-discharge cycles of rechargeable lithium batteries by more than 3 times;

2. Can be used for high temperature resistant coatings and refractory materials. It can react with organic matter as the raw material of organic silicon polymer material;

3. It can be applied to coating to form nano-silicon particle film, which is widely used in solar energy;

4. Nano-spherical silicon powder and diamond are mixed under high pressure to form nano-silicon carbide-diamond composite material, which can be used as a tool to provide strength and toughness;

5. As a nano-silicon carbon anode material for lithium-ion batteries, nano-silicon powder has a high theoretical specific capacity (theoretical value of 4200mAh/g), which is much higher than that of carbon materials;

6. More than ten kinds of silicon nanoparticles/silicon oxide nanostructures have been designed on silicon nanoparticle substrates, realizing photoluminescence in the main band from near-ultraviolet to near-infrared and low-threshold electroluminescence under forward or reverse bias. Luminescence, photoluminescence and electroluminescence models were proposed, which laid the foundation for the realization of silicon-based optoelectronic integration.
