The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Tourists and business trips have plummeted. On the booking website, there are a large number of air tickets for local routes with a price reduction of nearly 90% compared with the original price and only tens of yuan for a one-way trip.
In February, China's aviation industry recorded its largest single-month loss of 24.59 billion yuan, of which airlines lost 20.96 billion yuan.
Data from the Civil Aviation Administration of China showed that in February, the number of passengers traveling by air fell 84.5% year-on-year to 8.34 million.
The stagnation of the Asian aviation industry has brought volatility to Amorphous boron powder,Amorphous boron powder overview,Amorphous boron powder application,Amorphous boron powder price,Amorphous Boron Powder Supplier.
Amorphous boron powder overview
Boron powder is black or dark brown powder, which can react with fluorine at room temperature and is not corroded by alkali and hydrofluoric acid aqueous solution. Boron powder is also known as amorphous boron. Boron has high mass calorific value and volume calorific value. It is a light brown to gray-black powder with active chemical properties, but it is relatively stable at room temperature and will be oxidized when the temperature reaches 300 degrees Celsius. The ignition level is very high, requiring 700 degrees Celsius to ignite. Boron powder can react with oxygen, nitrogen, sulfur, or directly combine with some metals to form some borides.
Boron is an essential micronutrient for plant health and agricultural growth and development. The importance of boron has been shown to be vital in plant production since the early 1920s. Low concentrations of borate are used in agriculture as a micronutrient in fertilizers.
Boron can be divided into crystalline boron and amorphous boron:
Crystalline boron is dark gray with high hardness, similar to diamond hardness, and is often used to replace diamond to make tools or drill bits. It is less conductive but increases with temperature, unlike the conductivity of metallic conductors.
The chemical properties of amorphous boron are more reactive than crystalline boron. Crystalline boron is quite stable at room temperature, can only react with fluorine, and can only react with non-metallic elements such as nitrogen, oxygen, chlorine, sulfur, bromine, iodine and so on at high temperature. Amorphous boron is relatively active, oxidizes slowly in air, and almost reacts with most metal elements to form non-integral borides at high temperatures. It reacts with water vapor under red heat to generate metaboric acid and hydrogen.
Amorphous boron powder application
Amorphous boron powder is an important energy material. In the composite solid propellant used as solid fuel, the calorific value of boron is more than twice that of carbon, about twice that of aluminum and magnesium, and more than twice that of magnesium. Its volume is almost three times the calorific value of hydrocarbon fuels, its density is only slightly lower than that of aluminum, and its volumetric calorific value is the highest. In terms of its energy, boron should be the best fuel, not a metal. Due to the irregular shape and large specific surface area of amorphous boron, its ignition temperature is greatly reduced.
Amorphous boron powder is mainly used in metallurgy, medicine, ceramics, nuclear industry, chemical industry and other industries. It can be used in alloys in the form of compounds or as additives, and can also be used as catalysts for organic chemical reactions. important raw material.
