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. As of press time, gold was trading at $1,918 an ounce, down 7.9% from its March 8 peak. Rising gold prices may also have an impact on the metal 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. 

The metal powder preparation method can be divided into: reduction method,
electrolysis method, grinding method, atomization method, etc. according to the
preparation process. At present, the two most advanced powder making processes
commonly used in China are the argon atomization method and the plasma rotating
electrode method.

Argon atomization

The argon atomization method is a pulverizing method that uses fast-flowing
argon gas to impact metal liquid, break it into fine particles, and then
condense into solid powder.

Plasma rotating electrode method

The plasma state is called the fourth state of matter. The plasma rotating
electrode atomization (PREP method) powder making process can be simply
described as: the metal or alloy is made into a consumable electrode, and the
end of the consumable electrode is in the coaxial plasma arc Under the action of
the heating source, the liquid film is melted to form a liquid film. The liquid
film is thrown out at a high speed under the action of the rotating centrifugal
force to form droplets. The molten droplets rub against the inert gas (argon or
helium) in the atomization chamber, and further under the action of shear
stress. Broken, and then the droplets are rapidly cooled and solidified into
spherical powder under the action of surface tension.

The metal powder produced by the plasma rotating electrode method has the
following advantages:

High sphericity, smooth surface, good fluidity, and high bulk density, so the
powder uniformity is good, and the printed product is dense; the powder particle
size is small, the particle size distribution is narrow, the oxygen content is
low, and the printing time is less/no spheroidization And agglomeration
phenomenon, good melting effect, high product surface finish, and the
consistency and uniformity of printing can be fully guaranteed; there is
basically no hollow powder and satellite powder, and there will be no air gaps
and curls caused by hollow balls during the printing process. Defects such as
penetration and precipitation pores and cracks.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the metal powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these “payoffs” in the early pandemic environment.
