How much is the price of iridium per gram?
In the field of rare metals, iridium has always attracted much attention. Many people have the question: how much is the price of iridium per gram? Behind this seemingly simple question lies a complex pricing logic.
At present, the price of pure iridium given by Rongnengtong today is 890 yuan per gram. However, this price is not fixed and is constantly changing. As a metal with key applications in many high - end fields, the price of iridium is influenced by various factors such as global supply - demand relationships and economic situations. For example, in electronic chip manufacturing, due to its good electrical conductivity and stability, iridium is used to manufacture high - precision electronic components. In the aerospace field, because of its high - temperature resistance and high - strength characteristics, iridium has become an ideal material for manufacturing key components of aircraft. Once the demand for iridium in these industries surges and the supply cannot keep up in a timely manner, the price of iridium will rise rapidly.
If it is crude iridium, the situation is more complicated. The iridium content in crude iridium is uncertain, so the first step is to detect its content. Generally, there are many detection methods, and common ones include chemical analysis and spectral analysis. Chemical analysis accurately determines the proportion of iridium in crude iridium through a series of chemical reactions. Spectral analysis, on the other hand, uses the unique spectral characteristics of the iridium element to quickly and accurately determine its content.
After detecting the content of crude iridium, there is a basis for its recycling price. Usually, the higher the content, the higher the recycling price. This is because high - content crude iridium can yield more pure iridium during the purification process, reducing refining costs and resource consumption. Suppose one type of crude iridium has a content of 50% and another has 80%. Under the same market price, the recycling price of the 80% - content crude iridium will definitely be higher because it can produce more pure iridium. Practitioners in the recycling industry will also carefully evaluate the value of each batch of crude iridium based on the content and market price to ensure fair and reasonable transactions.
In - depth Analysis of the Characteristics and Applications of Platinum - Iridium Alloy
In the vast world of alloy materials, platinum - iridium alloy stands out with its unique properties and has attracted much attention in the fields of materials science and industrial applications. The following will elaborate on six significant characteristics of platinum - iridium alloy in detail.
Excellent basic properties: Platinum - iridium alloy performs outstandingly in basic properties such as melting point, density, hardness, strength, and elasticity, ranking at a relatively high level among various alloys. More importantly, as the iridium content and proportion in the alloy gradually increase, these performance advantages become more prominent, and the overall performance is further optimized. For example, in the aerospace field, platinum - iridium alloy with a high iridium content can be used to manufacture high - temperature - resistant and high - strength engine components, ensuring the safe operation of aircraft in extreme environments.
Unique precipitation - strengthening effect: When the iridium content in the platinum - iridium alloy exceeds 10% of the total alloy amount, the precipitation - strengthening effect will appear. Moreover, as the iridium content continues to rise, this effect becomes more obvious. However, compared with other alloys, the precipitation rate of platinum - iridium alloy is relatively low. In practical applications, this characteristic enables the platinum - iridium alloy to maintain good stability while maintaining high strength, making it suitable for the manufacture of precision instruments with high requirements for material stability.
Special electrical and thermoelectric properties: The electrical properties of platinum - iridium alloy are rather special. When the iridium concentration in the alloy decreases, its resistivity also decreases, while the temperature coefficient of resistance increases. In addition, platinum - iridium alloy itself has a low contact resistance, but once it is contaminated by an organic atmosphere, the contact resistance will increase sharply. In terms of the thermoelectric effect, when platinum and iridium are connected into a closed loop and the two nodes are placed in heat sources with different temperatures, a thermoelectromotive force will be generated in the loop, and as the iridium concentration decreases, this thermoelectric effect gradually weakens. These characteristics make platinum - iridium alloy have important applications in fields such as electronic components and temperature sensors.
Super - strong chemical corrosion resistance: The combination of platinum and iridium greatly enhances the chemical corrosion resistance of the alloy. When the iridium content in platinum exceeds 30%, the formed platinum - iridium alloy has extremely strong corrosion resistance. Even if it is placed in highly corrosive "aqua regia", it can remain stable, not be corroded, and not dissolve. This characteristic makes platinum - iridium alloy widely used in corrosive environments such as the chemical industry and the ocean, such as manufacturing the inner lining of chemical reaction kettles and key components of ocean monitoring equipment.
Volatile weight - loss characteristics: The volatile weight - loss characteristics of platinum - iridium alloy are closely related to the iridium concentration and heating temperature. As the iridium concentration and heating temperature decrease, the volatile weight - loss of the alloy gradually weakens. In applications in high - temperature environments, this characteristic helps to maintain the stability of the material, reduce material loss caused by volatilization, and extend the service life of equipment.
Relationship between processing performance and iridium content: As the iridium content in platinum - iridium alloy increases, the deformability of the alloy gradually deteriorates. This means that when processing platinum - iridium alloy, the iridium content needs to be controlled. If the iridium content is too high, it will bring great difficulties to processing, and even secondary processing may not be possible. In actual production, it is necessary to reasonably adjust the iridium content according to specific processing requirements and product performance requirements to ensure that the alloy can not only meet performance needs but also have good processing performance.
