Platinum rhodium crucibles are mainly used for high-temperature material analysis and laboratory research. It is an experimental vessel made of platinum rhodium and other metal element alloys, with good chemical stability, high temperature resistance, corrosion resistance, and electrical properties. Platinum rhodium crucibles are commonly used for high-temperature material analysis and are widely used in fields such as chemical industry and petrochemicals.
The production methods of platinum rhodium crucibles include static pressing, hot pressing, and vacuum electroslag melting. Among them, the platinum rhodium crucible prepared by vacuum electroslag melting method has the characteristics of uniform microstructure, high strength, and good corrosion resistance. It is often used to determine the physical properties such as melting point, combustion temperature, and thermal decomposition temperature of metal and non-metal materials. Its stability at high temperatures ensures the accuracy and reproducibility of experimental results. Used for catalyst preparation, gas-phase reactions, organic synthesis, and inorganic chemistry experiments.
Characteristics and Applications of Platinum Rhodium Crucibles
Chemical stability: Platinum rhodium crucibles can maintain stability in high temperature and strong acid-base environments, without chemical reactions, ensuring the accuracy of experiments.
High temperature tolerance: It has good high temperature resistance and can withstand very high temperatures, making it suitable for experiments in high-temperature environments.
Corrosion resistance: It has strong resistance to most chemical reagents and will not absorb moisture or be corroded by chemical reagents.
Electrical performance: It has good electrical performance and is suitable for experimental environments that require stable electrical performance.
Cleaning and maintenance: Platinum rhodium crucibles must be kept clean, with bright inside and outside. After long-term burning, the surface of the platinum crucible may become dull and dull, and over time it may penetrate deep into the interior, causing the crucible to become fragile and break. Therefore, unclean materials must be removed. It can be boiled and cleaned in dilute hydrochloric acid or dilute nitric acid. Among them, dilute hydrochloric acid is more convenient and can be prepared into a (1-1.2) mol/L hydrochloric acid solution. Note that the dilute hydrochloric acid used should not contain oxidants such as nitric acid, nitrate, halogen, etc. If it cannot be cleaned with dilute acid, use potassium persulfate, sodium carbonate, or borax to melt and clean. If there are still stains or blackening on the surface, use fine sand that passes through a 100 mesh sieve without sharp edges and corners, moisten with water and gently rub to restore the surface luster.
