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 tantalum silicide 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.
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.
