0.5mm/10cm high purity gold wire diameter pure gold wire gold electrode purity 99.99 gold wire inert anode
The materials used in our high purity gold wire are purified by vacuum melting method, vacuum distillation method, single crystal method, electrolytic refining method, etc. The purity reaches more than 99.99%. High purity gold melting point 1064.43℃, boiling point 2808℃, relative density 19.32, resistivity (20°C-) 2.4μΩ-cm, high purity gold is chemically stable, with strong corrosion resistance, in the air from room temperature to high temperature are generally not oxidized, not dissolved in a single hydrochloric acid, nitric acid, sulfuric acid and other strong acids, only dissolved in a mixture of hydrochloric acid and nitric acid (i.e. aqua regia) to generate Chloroauric acid H[AuCl4]; At room temperature when there is oxygen, gold can be dissolved in a solution containing potassium cyanide or sodium cyanide, the formation of stable complex M[Au(CN)2]; Gold can also be dissolved in the content of thiourea solution; Also dissolved in the acidic solution with chlorine gas. Gold does not act with alkali solution, but in the molten state can generate NaAuO2 with sodium peroxide. gold valence -1, -2, +1, +2, +3, +5, +7, etc., the oxide has gold trioxide Au2O3, chloride has gold trichloride AuCl3. in acidic medium, chloroauric acid H[AuCl4] or complex M[Au(CN)2] can be metal zinc (zinc powder or zinc) Wire), sodium sulfite, hydrazine hydrate, etc. reduced to monomeric gold powder, alkali metal sulfide will corrode gold, generating soluble gold sulfide.
