2021 is the 100th anniversary of the founding of the Communist Party of China and an extraordinary year for the magnesium industry. Magnesium alloy materials have helped the "tianwen-1" probe successfully land on the surface of Mars, the Tianhe core module enters the space station, the application of magnesium battery materials and magnesium building templates, and the green and low-carbon development of magnesium smelting. The major events of this year's magnesium industry are like knots on a long rope, which string up the flowing time, which is unforgettable and worth remembering for a long time.
It is of great significance to recycle the lead antimony alloy produced in the smelting and consumption of lead and antimony. In this paper, the saturated vapor pressure, separation coefficient and gas-liquid equilibrium composition diagram of pure lead and pure antimony in the temperature range of 923 ~ 1373 K are calculated. The feasibility of vacuum distillation separation of lead antimony alloy is analyzed from the perspective of thermodynamics.
As an essential basic material and important strategic material for national economic development, the development trend of non-ferrous metal industry in 2021 can be described as "jubilant". "From January to November 2021, the output of 10 kinds of common non-ferrous metals reached 59.107 million tons, a year-on-year increase of 6.3%. The total investment in fixed assets increased by 6.9% year-on-year. The profits of non-ferrous metal enterprises above Designated Size reached 341.01 billion yuan."
Since the launch of the major science and technology project of "rare and precious metal material genetic engineering" in 2018, Yunnan Province has broken through a number of advanced technologies of material genetic engineering and developed a number of rare and precious metal new material products, of which more than 10 products have realized industrialization or iterative upgrading, supporting the leapfrog innovative development of Yunnan rare and precious metal new material industry.
On January 7, Boeing, an aerospace manufacturer, has cooperated with titomic, a Melbourne company with titomic kinetic fusion (TKF) 3D printing process, to further promote additive manufacturing in the space field.
A few days ago, the exhibition of "charm is boundless, powerful country has titanium all the way" sponsored by China Nonferrous Metals newspaper and titanium, zirconium and hafnium branch of China Nonferrous Metals Industry Association was grandly held on the first floor of China Nonferrous Metals Industry Office Building in Beijing. The exhibition has received extensive attention from all units stationed in the building and achieved good response.
