Product Overview
Lithium tetraborate, 99% (metals basis) is a high-purity inorganic compound widely recognized for its exceptional fluxing properties in laboratory and industrial applications. This anhydrous, white crystalline powder exhibits low hygroscopicity, ensuring stability during storage and handling. Its high lithium content and boron-oxygen structure make it an ideal fusion agent for X-ray fluorescence (XRF) sample preparation, where it facilitates complete dissolution of oxides and silicates at temperatures as low as 900°C. The 99% metal basis purity guarantees minimal interference from trace impurities, making it suitable for analytical techniques requiring high precision. In metallurgical applications, it serves as a flux for refining non-ferrous metals, while in ceramics, it lowers melting points and improves glass transparency. The compound’s consistent particle size distribution ensures uniform mixing and predictable performance in formulations. Unlike sodium-based fluxes, lithium tetraborate produces glasses with lower viscosity, enabling better sample homogeneity. Its compatibility with platinumware and resistance to thermal shock further enhance its utility in high-temperature processes. The product is packaged under inert conditions to prevent moisture absorption, maintaining its reactive properties until use.
FAQs
1. What is the melting point of lithium tetraborate?
The melting point of lithium tetraborate is approximately 917°C, making it suitable for high-temperature applications where lower-melting fluxes would decompose or volatilize.
2. Can this be used as a substitute for lithium metaborate in XRF?
While both are lithium borate fluxes, lithium tetraborate has a higher boron content and different fusion characteristics. It produces glasses with lower viscosity, which may require adjustments to fusion protocols compared to metaborate.
3. How does moisture affect the performance of this product?
Moisture absorption can lead to clumping and reduce the effective fluxing capacity. The product is packaged to minimize exposure, but prolonged storage in humid conditions may require drying before use.
4. What safety precautions should be taken when handling this compound?
Use standard laboratory safety measures: wear gloves, goggles, and work in a well-ventilated area. Avoid inhalation of dust and skin contact, as lithium compounds can cause irritation.
5. Is this compatible with platinum crucibles?
Yes, lithium tetraborate is compatible with platinumware at typical fusion temperatures, unlike sodium-based fluxes that can corrode platinum at high temperatures.
