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 tantalum silicide.
What is Tantalum silicide?
Tantalum disilicide chemical formula is TaSi2. It has excellent properties such as high melting point, low resistivity, corrosion resistance, high temperature oxidation resistance, and good compatibility with silicon, carbon and other matrix materials.
Tantalum disilicide Uses
Tantalum disilicide is mainly used in electric heating elements, high temperature structural components, gate materials, connection circuits of integrated circuits, high temperature oxidation resistance coatings, cermets, ceramic matrix composites, aerospace, engines, and other fields.
Tantalum disilicide is a kind of refractory metal silicide.
Metal silicide refers to the hard compound formed by transition metal and silicon. Due to the large radius of silicon atoms, it cannot form interstitial compounds with transition metals, so these hard compounds have stable chemical composition and good oxidation resistance.
Metal silicide has similar electrical conductivity, high temperature performance, oxidation resistance and compatibility with silicon integrated circuit production process. Transition metal silicide can be used for low resistance gate and internal wiring, resistance contact.
Tantalum silicide Production
The preparation methods of tantalum silicide include combustion synthesis (CS) or self-propagating high temperature synthesis (SHS), and arc melting.
Combustion synthesis or self-propagating high temperature synthesis is a method for the synthesis of intermetallic compounds by the exothermic reaction of elements / compounds. It has the advantages of simple equipment, low energy consumption and short synthesis time. Its main disadvantages are fast reaction speed, difficult process control and easy existence of miscellaneous phases.
The combustion synthesis of tantalum silicide needs preheating to initiate the reaction to realize the synthesis, but there is a phase other than disilicide.
Arc melting generally takes a long time to homogenize, and the loss of silicon caused by volatilization in the melting process may lead to the formation of some impurity phases. Because of its jet temperature up to 10000 ℃ and jet speed up to 300-400m/s, plasma spraying technology has the advantages of high temperature melting, rapid solidification and near-net forming, and it is not limited by shape or size, so it is easy to realize its short process forming, so it has gradually developed into a new type of parts forming technology, which has been used to prepare some parts. Tantalum silicide powder is made into bulk material by plasma spraying technology, which requires high purity tantalum silicide powder as raw material. Therefore, how to obtain high purity tantalum silicide powder (without impurity phase formation) becomes the key.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine. Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the tantalum silicide would keep being influenced by the high energy prices.
