The following are some common precious metals: Gold (Au), gold is one of the most well-known precious metals, with good electrical conductivity and corrosion resistance. Gold is widely used in jewelry, investment reserves, and the electronics and communications industries; Silver (Ag), silver is also an important precious metal with excellent thermal conductivity and electrical conductivity. Silver is widely used in jewelry, tableware, photography, electronic equipment and other fields; Platinum (Pt), platinum is a rare and expensive precious metal with a high melting point, corrosion resistance and high temperature resistance. Platinum is often used in automotive catalysts, chemical laboratory equipment, jewelry, etc.; Palladium (Pd), palladium is a light precious metal with good catalytic properties and corrosion resistance. Palladium is widely used in automotive catalysts, electronic equipment, jewelry, etc.; Rhodium (Rh), rhodium is a rare precious metal with good heat resistance and corrosion resistance. Rhodium is commonly used in glass manufacturing, chemical laboratory equipment and other fields; these precious metals have important application value in various industries.

Due to their scarcity and investment value, precious metals are also regarded as a safe-haven asset and investment tool by some investors.

[0003] Crucible is an important component of chemical instruments. It is needed when melting precious metals. It is a container for melting and refining metal liquids and for solid-liquid heating and reaction. It is the basis for ensuring the smooth progress of chemical reactions. There are many types and specifications of crucibles. When used, they are not restricted by production scale, batch size and type of smelting materials. They can be selected arbitrarily, have strong applicability, and can ensure the purity of the smelted material. After the crucible is heated, the content inside the crucible needs to be poured into a beaker or other storage item.
