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 Carbide 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. 

Introduction to Tantalum Carbide TaC Powder
Tantalum carbide or TaC is a light brown metallic cubic crystal powder, belonging to the sodium chloride cubic crystal system. The density is 14.3g/cm3.
Insoluble in water, insoluble in inorganic acid, soluble in hydrofluoric acid and nitric acid mixed acid and decomposition. It has strong oxidation resistance and is easily melted and decomposed by potassium pyrosulfate. Has high conductivity, and resistance of 30Ω at room temperature, showing superconductivity.
Tantalum carbide is used for powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy cutting tools, molds, and additives for wear and corrosion resistance structural components to improve the toughness of alloys. The sintered body of tantalum carbide shows a golden color and can be used as watch decoration.

Preparation Methods of Tantalum Carbide TaC Powder
1. In industry, mix tantalum pentoxide powder with solid carbon ball mills, get the mixture reduced and carburized in a non-oxidizing atmosphere (mainly vacuum and argon atmosphere) at 1700℃, to prepare TaC powder with a particle size greater than 2μm.
2. Nano tantalum carbide powder was prepared by heat treatment in the non-oxidizing atmosphere with the liquid precursor method. 5mL of anhydrous ethanol was added into a small beaker containing 0.50gTaCL5, and stirred evenly with a glass rod. Then, it was put into an ultrasonic cleaner with a heating temperature of 55℃ and a working frequency of 40kHz, ultrasonic power was 80W. After ultrasonic oscillation for 5-10min, 0.10g nano-activated carbon was added, and the oscillation continued for 15-20min. Pour it into the crucible and coat it evenly on the inner wall, and dry it with a hot fan. The crucible with the sample was placed in a vacuum hot pressing furnace, and high-temperature treatment was carried out at 1300℃ in a vacuum of 100Pa or hydrogen atmosphere; Or at 1400℃ in argon atmosphere, holding time is 0.5h, the heating rate is 20℃/min. After the experiment, brush the products in the crucible with a brush. 
3. Heat in the air to convert to tantalum pentoxide. Can be fused with potassium pyrosulfate.  By metal tantalum and carbon or tantalum pentoxide and black in an inert atmosphere heated to 1900℃ reaction prepared.
4. Use tantalum pentoxide and methane as the reaction gas, argon as the carrier, using silicon carbide resistance from the external radiation heating, carbonization, or tantalum pentoxide mixed with carbon black, pressurized powder molding, heating in hydrogen or vacuum.
 
Applications of Tantalum Carbide TaC Powder
It is widely used in industry and the military. In cemented carbide, it is widely used as a kind of additive. Its main function is to improve the high-temperature strength of cemented carbide and inhibit the growth of tungsten carbide particles. 
In cutting tools, used as a hard coating to increase the chemical resistance and wear resistance of the base metal; 
In the military, it can be used as a coating for jet engine turbine blades and rocket nozzles, which can significantly improve their ablative resistance and prolong their service life. 
Because of its good conductivity, it can also be used as electrode material, using electric discharge wire cutting into complex shapes; 
And as the second phase particle reinforced metal matrix composites, it can be used in aerospace, metallurgy, building materials, electric power, hydropower, mining, and other fields.

A preparation developed in China; the comfort and the multifunctional properties of nanomaterials make "dead skin" capable of sensing again. Electronic skin is artificial skin that mimics the function of human skin. Recently, the world-renowned journal Advanced Science reported a simple and highly programmable electronic skin on a leather substrate developed by a Chinese team, which combines the natural complex structure of leather, the comfort of wearing, and the multi-functional properties of nanomaterials. , so that the "dead skin" has the ability to sense again.

In the future, Tantalum Carbide powder will be used in various high-tech fields, and the market demand for Tantalum Carbide powder will also be great. Please contact us for more information on Tantalum Carbide powder.
