💡 Commercial Applications
Terbium, a rare earth element with the atomic number 65, has several notable commercial and industrial applications. One of the primary uses of terbium is in the production of energy-efficient fluorescent lamps, where it is employed as a phosphor to create green and yellow light. Additionally, terbium is utilized in the production of permanent magnets, particularly in devices such as headphones and speakers, due to its ability to enhance the magnetic properties of materials.
In the realm of drug and medication applications, terbium plays a crucial role in the field of medical imaging. Terbium-based contrast agents are used in magnetic resonance imaging (MRI) scans to improve the visibility of specific tissues and organs within the body. These contrast agents are designed to enhance the contrast between different tissues, allowing healthcare providers to diagnose a wide range of medical conditions with greater accuracy.
⚗️ Chemical & Physical Properties
Terbium is a silvery-white metallic element that is relatively stable in air. It does not have a distinct odor.
The molar mass of Terbium is approximately 158.93 g/mol, and its density is about 8.23 g/cm³. In comparison, common food items such as sugar have a molar mass of 342.3 g/mol and a density of 1.59 g/cm³.
The melting point of Terbium is 1356 °C, and its boiling point is 3230 °C. In contrast, common food items such as butter melt at around 32°C and boil at approximately 178°C.
Terbium has limited solubility in water and exhibits low viscosity. This is in stark contrast to common food items like salt, which are highly soluble in water and have a higher viscosity.
🏭 Production & Procurement
Terbium, a rare earth metal with the atomic number 65, is primarily produced through ion exchange or solvent extraction processes. The ion exchange method involves passing a solution containing terbium ions through a resin bed to selectively separate and collect the terbium. Alternatively, solvent extraction utilizes specialized organic solvents to extract terbium ions from a liquid solution.
Terbium can be procured through various methods including purchasing from specialized chemical suppliers, online vendors, or directly from manufacturers. Due to its scarcity and high demand in certain industries, the cost of terbium can be relatively high compared to more abundant metals. Once procured, terbium can be safely transported in sealed containers to prevent oxidation and contamination during transit.
In the transportation of terbium, precautions must be taken to ensure its stability and prevent exposure to moisture or other reactive substances. Proper labeling and handling procedures should be followed to comply with regulatory guidelines and ensure the safe transport of terbium. Additionally, considering the specialized nature of terbium applications, careful consideration should be given to the packaging and storage requirements to maintain the quality and integrity of the material.
⚠️ Safety Considerations
Safety considerations for Terbium are essential due to its potential hazards. Terbium is a reactive metal that can ignite spontaneously in air, presenting a fire hazard. It is also a skin and eye irritant, causing irritation upon contact. Proper handling and storage procedures must be followed to minimize the risk of accidents or injuries.
Hazard statements for Terbium include: “Causes skin and eye irritation”, “May cause respiratory irritation”, and “May cause an allergic skin reaction.” These statements highlight the potential dangers associated with exposure to Terbium, emphasizing the importance of using appropriate personal protective equipment and following safe handling practices to prevent adverse effects.
Precautionary statements for Terbium recommend wearing protective gloves, clothing, eye protection, and face protection to minimize the risk of exposure. It is advised to avoid breathing dust/fume/gas/mist/vapors/spray and wash thoroughly after handling. In case of skin irritation or rash, seek medical advice and attention. These precautions are crucial in safeguarding individuals working with Terbium from potential harm or health hazards.
