Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.
Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."
According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.
The volatile oil prices in the international market will continue to affect lots of industries and the supply of many 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.
