| Property： | Sponge platinum, is grey, spongy and pure metal on which there isn’t any inclusion that can be seen. Its density is 21.4g/cc, melting point is 1773℃. The wear ability, malleability and plasticity of platinum are so well as that of gold, its electric conductivity is the best. Aqueous solutions of alkali and acid are inoperative to platinum, only aqua regia can dissolve platinum. Platinum can be corroded by molten alkali and cyanide. |
| Use： | Platinum is used for making resistance elements, relay contacts, electric thermocouples, printed circuits, wares for physical and chemical analysis and crucibles. |
| Transportation & Use： | In the course of transportation, attentions must be paid to prevent damp, pollution and collision or break of the pack bottles. In the course of using, attentions must be paid to prevent pollution, to prevent contact with aqua regia, molten alkali and oxidant. The molten platinum can’t be contacted with carbon. |
