Global Silicon Nitride powder market trend 2024-2026 What is Silicon Nitride Si3N4 Powder used for? by Newshealthreformwatch

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 Silicon Nitride powder are still very uncertain.

Introduction to Silicon Nitride Si3N4 Powder
Silicon nitride or Si3N4 is a kind of white powdery crystal; The melting point is 1900, and the density is 3.44g/cm3 (20). There are two variants: the α type which is a hexagonal dense packing structure, and the β type which is a crystalline structure. Silicon nitride is gray when it has impurities or excess silicon. 
 

Physicochemical Properties of Silicon Nitride Si3N4 Powder
Silicon nitride hardly interacts with water. It slowly hydrolyzes to ammonium salt and silicon dioxide in a strong acid solution. Soluble in hydrofluoric acid, and does not act with dilute acid. A solution of strong alkali slowly corrodes the silicon nitride, and the molten strong alkali quickly converts the silicon nitride to silicates and ammonia. Above 600, Si3N4 can reduce transition metal oxides (see transition elements), lead oxide, zinc oxide, and stannic oxide, and release nitrogen oxide and nitrogen dioxide.
Silicon nitride is very strong, especially the hot-pressed silicon nitride. It is one of the hardest substances in the world. It is very high-temperature resistant, and it can maintain its strength at a high temperature of 1200. After heating, it will not melt into a melting body, until 1900 it will decompose. And it has amazing chemical corrosion resistance, almost all inorganic acid and 30% of the following caustic soda solution, also can withstand a lot of organic acid corrosion. It is also a kind of high-performance electrical insulation material.

Applications of Silicon Nitride Si3N4 Powder
Silicon nitride is an important structural ceramic material with hardness, lubrication, and wear resistance. It is oxidation resistant at high temperatures. And it can also resist cold and hot shocks. Even though heated to more than 1000 in the air, through sharp cooling and then sharp heating, it will not break.
Because of such excellent characteristics, it is often used to manufacture bearings, turbine blades, mechanical seal rings, permanent molds, and other mechanical components. Using silicon nitride ceramic which is resistant to high temperature and not easy to heat transfer to manufacture the heating surface of engine parts can improve the quality of diesel engines, save fuel and improve the thermal efficiency.
In the mechanical industry, silicon nitride ceramics are used as bearing ball bearings, rollers, ball seat rings, molds, new ceramic cutting tools, pump plungers, spindle sealing materials, etc.
In the chemical industry, silicon nitride ceramics are used as wear and corrosion-resistant components, such as ball valves, pump bodies, combustion carburetors, filters, etc.
In the metallurgical industry, because of its properties of high-temperature resistance, small friction coefficient, and self-lubrication, and, for most metals, the alloy solution is stable, so silicon nitride ceramics can be used to make metal material processing die, such as dial core bar, extrusion, wire drawing die, roll, transfer roll, heating fixture, hot couple set camps, metal heat treatment support, crucibles, liquid aluminum guide camp, aluminum lining, etc.
Silicon nitride ceramic materials are also widely used in the electronics, military, and nuclear industries.
