The material used in our high-purity gold wire is purified by vacuum melting method, vacuum distillation method, single crystal method, electrolytic refining method and other purification processes, and the purity reaches more than 99.99%. High-purity gold has a melting point of 1064.43°C, a boiling point of 2808°C, a relative density of 19.32, and a resistivity (20°C-) 2.4μΩ·cm. The high-purity gold has stable chemical properties and strong corrosion resistance. Generally, it does not oxidize to high temperature, insoluble in a single strong acid such as hydrochloric acid, nitric acid, and sulfuric acid, but only soluble in a mixed acid of hydrochloric acid and nitric acid (ie aqua regia) to produce chloroauric acid H[AuCl4]; Gold can be dissolved in a solution containing potassium cyanide or sodium cyanide to form a stable complex M[Au(CN)2]; gold can also be dissolved in a solution containing thiourea; it can also be dissolved in an acidic solution with chlorine gas in. Gold does not interact with alkaline solutions, but can generate NaAuO2 with sodium peroxide in the molten state. The valences of gold are -1, -2, +1, +2, +3, +5, +7, etc. The oxides are gold trioxide Au2O3, and the chlorides are gold trichloride AuCl3. In acidic medium, chloroauric acid H[AuCl4] or complex M[Au(CN)2] can be reduced to elemental gold powder by metal zinc (zinc powder or zinc wire), sodium sulfite, hydrazine hydrate, etc. Sulfide will corrode gold and produce soluble gold sulfide.
