1. Conductive materials: such as gold contacts/circuit boards \x0d\2. Catalyst \x0d\3. Blood vessels \x0d\4. Electrodes and other electroplating materials \x0d\5. Precious metal toner \x0d\6. Edible: edible gold foil \x0d\7. Textile materials. For example, gold, because of its unique physical and chemical properties, should be used in semiconductor integrated circuits and pen tips: it has extremely high corrosion resistance and stability; Good electrical and thermal conductivity; The nucleus has a large effective cross section to capture neutrons; The reflection ability of infrared ray is close to100%; It has various catalytic properties in gold alloys; It also has good manufacturability, can be easily processed into ultra-thin gold foil, micron gold thread and gold powder, and can be easily plated on the surfaces of other metals, ceramics and glass; Gold is easy to be welded and forged under certain pressure; It can be made into superconductors and organic gold, which are widely used in industry and modern high-tech industries, such as electronics, communications, aerospace, chemical industry, medical treatment and other fields. \ x0d \ x0d \ In the period of rising inflation (negative interest rate era), in order to avoid the loss of purchasing power of money, physical assets include real estate, precious metals (gold, silver, etc. ), jewelry, antiques, works of art, etc. It will often become the object of capital chasing.
