Global TaC powder market trend 2022-2028 Applications of Tantalum Carbide TaC Powder by Newsberpolitik

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 TaC powder 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.

Applications of Tantalum Carbide TaC Powder
Tantalum carbide is mainly used for cemented carbide, capacitors, electronic devices, high-temperature components, chemical equipment, and armor piercing shells.

1. Cemented carbide 
Tantalum carbide plays an important role in cemented carbide. It improves the properties of the alloy by improving the fiber structure and phase transformation dynamics, making the alloy have higher strength, phase stability, and processing deformation ability.  Tantalum carbide has a very high melting point (4000) and good thermodynamic stability. Tantalum is particularly effective in promoting nucleation and preventing carbon precipitation from nucleated brittle films formed during late solidification. Its main function is to prevent cemented carbide grain from growing up. In addition, it forms a third dispersion phase with TiC besides WC and Co, which significantly increases the thermal shock resistance, crescent hole wear resistance, and oxidation resistance of cemented carbide, and improves its redness and hardness. 
TaC is added into the alloy in different ways, which will greatly affect the properties of the alloy. On the other surface, the TiC-TaC-WC core phase formed by adding TaC to the alloy as TiC-TaC-WC solid solution has a larger sub-crystal size and smaller microscopic strain than the TiC-TaC-WC core phase, and the former one has better physical and mechanical properties and longer cutting life. 
 
2. Electronics industry 
In recent years, transition metal carbides have attracted much attention due to their chemical stability, high hardness, strong oxidation and corrosion resistance, low resistivity, and many other advantages. Carbide nanomaterials show great potential in metal coatings, tools, machine parts, and composites. Among all the carbide nanomaterials, silver carbide is one of the most popular materials, and also one of the materials with the greatest potential. Tantalum carbide not only inherits many advantages of carbide nanomaterials, but also has its own unique side, such as high hardness (Mohs hardness is 9-10 at room temperature, high melting point (about 3880), high Young's modulus (283-550 GPa), strong conductivity (conductivity is 32.7-117.4μ ω ·cm at 25), high-temperature superconductivity (10.5K), strong resistance to chemical decay and thermal shock, and high catalytic activity for ammonia decomposition and hydrogen separation. 
At present, tantalum carbide powder and whisk tantalum carbide have been prepared by means of carbothermic reduction, thermal plasma, solvothermal, sol-gel, microwave heating, alkali reduction, self-propagating high-temperature synthesis, and high-frequency induction heating sintering.
 
3. Superalloys
Among carbides, the best melting resistance is tantalum carbide (TaC) (melting point 3890) and hafnium carbide (HfC) (melting point 3880), followed by zirconium carbide (ZrC) (melting point 3500). These materials have excellent mechanical properties at high temperatures, far exceeding the best polycrystalline inks. Tantalum carbide, in particular, is the only material that maintains certain mechanical properties over the temperature range of 2900 to 3200. However, the disadvantage of tantalum carbide is that it is very sensitive to thermal shock, and the low thermal conductivity and high thermal expansion coefficient of carbide become the biggest obstacle to the application of aerospace materials. The addition of tantalum carbide to carbon/carbon composites will have higher thermal conductivity and lower thermal expansion conditions, and exert the oxidation resistance and ablative resistance of refractory metals.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.  

On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.  

Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.  

Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March.  It is also the highest since comparable data began in 1999.  

The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the TaC powder.
