Overview of Silicon Nitride Si3N4 Powder

Silicon nitride Si3N4 Powder is a compound of silicon and nitrogen. Si3N4 is the most thermodynamically stable in silicon nitride. It is a white, high melting solid, relatively chemically inert, attacked by dilute HF and hot H2SO4. It works very hard (MoHS is 8.5) and has high thermal stability.

Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, lubricity and wear resistance, and is an atomic crystal; it is resistant to oxidation at high temperatures. And it resists the effects of cold and cold, heats into the air to 1000°C or more, then cools sharply and then heats, it won't break. It is because of the excellent properties of silicon nitride ceramics that they are often used to manufacture mechanical components such as bearings, air turbine blades, mechanical seals, permanent molds, etc. If silicon nitride ceramics are resistant to high temperature and difficult to transfer, the heat absorption surface of engine components can be improved, which not only has good quality, but also saves fuel and improves thermal efficiency.

Product Characteristics of Silicon Nitride Si3N4 Powder

Low density, high temperature strength, excellent thermal shock resistance, excellent wear resistance, good fracture toughness, mechanical fatigue and creep resistance, good oxidation resistance.

Silicon nitride Si3N4 Powder is difficult to produce as a bulk material - it cannot be heated above 1850°C because it breaks down into silicon and nitrogen, which is well below its melting point. Therefore, the application of traditional hot pressing sintering technology is problematic. Bonding of silicon nitride powders can be achieved at lower temperatures by adding additional materials (sintering aids or "binders") that typically cause some degree of liquid phase sintering. A cleaner alternative is to use spark plasma sintering, where very rapid (several seconds) heating occurs by pulses of electrical current through the compacted powder. Dense silicon nitride compacts were obtained by this technique at temperatures of 1500–1700 °C.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.  

The EU foreign ministers' meeting was held in Brussels.  The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.  

EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.  

Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.  

A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.
