Silicon nitride is a kind of ceramic material with excellent thermal and chemical properties, which has high hardness, stable structure, low coefficient of thermal expansion, good oxidation resistance and corrosion resistance.
Silicon nitride is a compound of silicon and nitrogen. Si3n4 is the most thermodynamic stable in silicon nitride.
Since the beginning of this year, people around the world have felt the pressure of rising prices. Not only the rise in oil prices but also different industries have seen soaring prices. According to the latest data, from August 2021 to the present,
The European Commission has submitted to member states a new draft of sanctions against Russia, including an oil embargo. Some member states that rely heavily on Russian energy sought exemptions. Western media reported that the European Commission d
OPEC+, an oil producers' alliance led by Saudi Arabia and Russia, stuck to its original plan to increase output by just 432,000 b/d in June, continuing to defy calls from major consumers led by the United States to pump more oil to keep prices down.
US President recently decided to invoke a Cold War-era defense law to encourage domestic Si3N4 Powder. About Silicon Nitride Si3N4 Powder:Silicon nitride is a compound of silicon and nitrogen. Si3n4 is the most thermodynamic stable in sil
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 nex
Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appe
What is Silicon Nitride? Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, inherent lubricity, and wear resistance. It is an atomic crystal; it is r
Silicon nitride, as a compound synthesized mainly by artificial conditions, was successfully developed by foreign scientists more than 150 years ago. The silicon nitride (size about 2 × 5μm) naturally present on the earth until the ninetie
Heat is difficult to be transferred in a vacuum environment. This is a fundamental concept in classic physics and the knowledge learned in high school physics textbooks. But the latest research from the University of California Berkeley rese

Many countries have begun to study digital currencies, which will have little impact on world shape memory alloy prices in 2021 The Bank of Japan plans to start empirical experiments on digital currencies in the spring of 2021. The idea is divided in
Generally, transparent conducting oxides (TCOs) like antimony tin oxide and its nanoscale crystals combine transparency quality in the visible range of electromagnetic waves with high electrical conductivity making them considerable materials for several optoelectrochemcial applications. TCOs like antimony tin oxide nanoparticles are produced predominantly and extensively as thin layers and coatings. However, there has been a fast-growing trend and interest in obtaining nanosized crystals as sma
Nickel Titanium Alloy has a unique set of features that make it one of the most popular metal alloys. This includes its superior fatigue strength, resistance to corrosion and ferroelectricity as well as shape memory and superelasticity. The shape memory One of the most popular alloys is Nitinol, which incorporates nickel and titan. It's used extensively in medical devices including implants for orthopedics, endovascular prostheses, and stone extractors. It has many benefits, such as its l
