Global Silicon Nitride powder market trend 2023-2029 What is Silicon Nitride Si3N4 Powder used for? by Newsncnblue

Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months.  

With a lot of deserts, Qatar suffers from water shortages, and Qatar depends on food imports for a long time. Recently, the ongoing tension in Ukraine has caused global food supply tension and rising prices.

In addition to that, the geopolitical situation also affects the supply and prices of many commodities like the Silicon Nitride powder.

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.

The negative electrode material is the carrier of lithium ions and electrons during the charging process of the battery and plays the role of energy storage and release. In the battery cost, the negative electrode material accounts for about 5%-15%, which is one of the important raw materials for lithium-ion batteries. The global sales of lithium battery anode materials are about 100,000 tons, mainly in China and Japan. According to the current growth trend of new energy vehicles, the demand for anode materials will also show a state of continuous growth. At present, the global lithium battery anode materials are still dominated by natural/artificial graphite, and new anode materials such as mesh carbon microspheres (MCMB), lithium titanate, silicon-based anodes, HC/SC, and metal lithium are also growing rapidly.
Our company provides anode materials and Silicon Nitride powder. If you need to know more anode materials and Silicon Nitride powder, please feel free to contact us.
