query: Can you list 5 rare metals? Please rank them according to global demand.

reference:
Rare metals refer to metallic elements that have a low abundance in the Earth's crust, uneven distribution, or are difficult to mine. They play a very important role in high-tech fields and emerging industries. The ranking of global demand may vary with time and technological advancements, but the following are some rare metals that are widely in demand (not necessarily ranked by absolute demand, as this can vary at different times):

1. Cobalt (Co) - Cobalt is one of the key components of lithium-ion batteries, especially in electric vehicles and portable electronic products. In addition, it is also used in the manufacture of heat-resistant alloys, hard alloys, and catalysts.

2. Neodymium (Nd) - Neodymium is a rare earth metal mainly used in the production of strong magnets, such as high-performance permanent magnets, which are widely used in computer hard drives, wind turbines, and electric vehicle drive motors.

3. Lithium (Li) - Lithium is primarily used in the manufacture of lithium batteries, and with the increasing demand for electric vehicles and portable electronic devices, the demand for lithium has rapidly increased.

4. Silver (Ag) - Although silver is not as rare as the above metals, its demand in industry is enormous, mainly used in electronics, solar panels, jewelry, and currency manufacturing.

5. Ruthenium (Ru) - Ruthenium is a rare precious metal widely used in data storage for hard drives and large capacity servers, as well as in catalysts and electrochemical cells.

The demand for these metals is influenced by various factors such as the global economy, technological development, and policy support. Additionally, as time progresses and markets change, other rare metals such as tantalum, indium, rhenium, and other rare earth metals may also appear on the list of most demanded rare metals.

contexts: Rare metals refer to metals with low abundance in the Earth's crust and complex mining and extraction processes.

contexts: Lithium (Li): Used in battery manufacturing.

contexts: Cobalt (Co): Used in high-performance alloys and battery manufacturing.


query: Describe the steep and majestic Huashan.

reference:
Huashan stands alone in its beauty, towering into the clouds;
Sheer cliffs cut the sky, rugged rocks are steep and elegant.
Ancient pines and green bamboo, competing for beauty on the cliffs;
Monkeys cry and eagles fly, illuminated by the light of frost swords.

Precarious peaks like scissors, towering like swords pointing to the sky;
Narrow paths and steep slopes, no road but vines entwine.
Wind carries the scent, mist weaves, clouds emerge and intertwine;
A deep fairyland, difficult to navigate the heavenly ladder.

Jagged ridges intersect, dragon veins surge;
Perilous paths further entice, soaring and winding.
Lonely pine tips, eagles soar in the vast sky;
At the summit of Huashan, majestic and heroic in appearance.

contexts: Huashan is one of the Five Great Mountains.
