Abstract: s-shaped platinum rhodium 10 - namely 90% platinum thermocouple, platinum, rhodium (10%), the other is the pure platinum;
B platinum rhodium 30 - namely Platinum rhodium thermocouple, 70% of platinum, rhodium (30%), another is platinum (94%), rhodium (6%);
R type platinum rhodium 13 - namely 87% platinum thermocouple, platinum, rhodium (13%), another is pure platinum.
instrument taizhou double China specializing in the production of thermocouples, platinum, rhodium thermocouple, thermocouple, wear-resisting K type thermocouple, electric stove wire, high temperature thermocouple, heat resistance, compensation conductor, such as infrared thermometer thermometer table. As a platinum jewelry normally with Pt850, Pt900, Pt950, Pt999 is given priority to, the four categories. Platinum jewelry marks, with Pt and Pt/P said. PT900 said its platinum-based 90%, with other metal was 10%. While another known as white white jewelry, K gold and nickel, palladium, silver, zinc and other metal alloy, namely white K gold, both on the color is very close to, but it is two completely different types of metal.
S the platinum rhodium - 10 90% platinum thermocouple, platinum, rhodium (10%), the other is the pure platinum;
B platinum rhodium 30 - namely Platinum rhodium thermocouple, 70% of platinum, rhodium (30%), another is platinum (94%), rhodium (6%);
R type platinum rhodium 13 - namely 87% platinum thermocouple, platinum, rhodium (13%), another is pure platinum.
platinum rhodium wire is platinum based binary alloy containing rhodium, for continuous solid solution at high temperature. Rhodium alloy can be improved for platinum thermoelectric potential and ability to resist oxidation and acid corrosion. PtRh5, PtRhl0, PtRhl3, PtRh30 and PtRh40 alloy. More than 20% Rh alloy is not soluble in aqua regia.
