Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for Mg3N2 powder.
What is Magnesium Nitride?
Magnesium nitride, is an inorganic compound with the chemical formula Mg3N2. It belongs to the cubic crystal system. At room temperature, pure magnesium nitride is a yellow-green powder, but magnesium nitride containing a portion of magnesium oxide impurities is grayish white.
The molar mass of magnesium nitride is 100.95g/mol. Its density is 2.712g/cm3. Magnesium nitride is completely dissolved in acid and water, but partially dissolved in ether and ethanol.
The melting point of magnesium nitride is 1500 degrees. Magnesium nitride, like many metal nitrides, reacts with water to produce ammonia. Often used as a catalyst. React with acid or aqueous nonmetallic oxides to form ammonium salts and magnesium salts.
Magnesium nitride is ceramic in nature. Magnesium nitride has high corrosion resistance and greatly improves production efficiency. Magnesium nitride also has high thermal conductivity, as well as high corrosion resistance and temperature resistance. Magnesium nitride has another great importance because it is used as a catalyst for the synthesis of boron nitrogen.
What is Magnesium Nitride Used For?
Used as a catalyst when prepare the nitride of other elements with high hardness, high thermal conductivity, corrosion resistance, wear resistance and high temperature resistance. In the first successful synthesis of cubic boron nitride, the catalyst was magnesium nitride.
Used for high strength steel smelting additives. Magnesium nitride (Mg3N2) replaces desulphurized magnesium in construction steel smelting, which is beneficial to improve the density, strength, tension and bearing force of steel. In addition, the use of magnesium nitride (Mg3N2) desulfurization, can reduce the amount of other additives, thus helping to reduce the production cost of construction steel;
3. Used to prepare special ceramic materials;
4. For the manufacture of special alloy foaming agent;
5. For manufacturing special glass;
6. For catalytic polymer crosslinking;
7. For the recycling of nuclear waste;
How to Produce Magnesium Nitride?
At present, the main preparation methods of magnesium nitride include direct reaction method of magnesium powder with nitrogen, reaction method of magnesium with nitrogen in nitrogen plasma flow, magnesium coil explosion method in nitrogen atmosphere, low pressure chemical gas complementary product method, self-propagating high temperature synthesis method, nano magnesium nitride synthesis method, etc.
Recently, G. Soto et al. prepared amorphous magnesium nitride films with different Mg∶N ratios on Si substrates in a molecular nitrogen environment by pulse laser deposition. These methods limit their industrial production due to high cost, long process, complex equipment operation, or low yield of magnesium nitride.
Although the direct reaction of magnesium powder with nitrogen has industrial value, the production of magnesium nitride powder needs higher reaction temperature and longer reaction time, and the shape of particles is incomplete and easy to agglomerate, which can not meet the requirements of industrial quality. NH3 can be decomposed into N- with broken bonds more easily than N2, and the decomposed H2 can inhibit the formation of MgO, so ammonia gas can be used as the nitrogen source. Chen Faqin et al. used liquid ammonia as nitrogen source to prepare magnesium nitride powder by direct nitriding of magnesium powder. The following conclusions could be drawn: Through thermodynamic analysis, liquid ammonia could react with magnesium powder more easily than nitrogen to prepare magnesium nitride; High quality magnesium nitride powder with high purity and uniform powder particles can be prepared at 600℃ and ammonia atmosphere for 1h, then heated to 800℃, ammonia flow rate of 500ml/min and nitriding time of 1h.

Twitter recently announced that it had reached an agreement with Musk to take full ownership of the company for $54.20 per share, or about $44 billion in cash. After the deal, Twitter will become a privately held company. The deal, which has been unanimously approved by Twitter's board but still requires shareholder and regulatory approvals, is expected to close in 2022.
After Tesla CEO Elon Musk's acquisition of Twitter was finalized, Twitter founder Jack Dorsey sent out a series of six tweets expressing his expectations for Musk.
Dorsey called Twitter his biggest regret, saying, “The idea and service is all that matters to me, and I will do whatever it takes to protect both. Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step.
"In principle, I don't believe anyone should own or run Twitter," Dorsey goes on. He thinks the service is a public good.
He called Musk a "singular solution" to Twitter's problems, "Elon's goal of creating a platform that is" Maximally trusted and inclusive "is the right one." He wrote, "Thank you both for getting the company out of an impossible situation. This is the right path... I believe it with all my heart."
Besides, because of the ever-changing international situation, the supply and prices of international bulk Mg3N2 powder are still very uncertain.
