Product Characteristics and Application of Silicon Nitride Si3N4 Powder
Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation.
Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. Rising gold prices may also have an impact on the Silicon Nitride Si3N4 Powder,Overview of Silicon Nitride Si3N4 Powder,Silicon nitride Si3N4 powder application,The price of silicon nitride Si3N4 powder,Silicon Nitride Si3N4 Powder Supplier prices.
According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%.
The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation.
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.

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.
