Product Overview
Lithium tetraborate (Li₂B₄O₇) in Puratronic grade offers exceptional purity at 99.998% (metals basis), making it ideal for applications demanding ultra-low impurity levels. This anhydrous, white crystalline powder serves as a critical fluxing agent in X-ray fluorescence (XRF) sample preparation, ensuring minimal background interference during elemental analysis. Its high thermal stability and low melting point (917°C) enable efficient fusion of refractory oxides, while the absence of alkali metal contaminants prevents spectral overlaps in analytical techniques. The reagent’s hygroscopic nature requires careful handling under dry conditions to maintain its chemical integrity. Unlike conventional borate fluxes, this grade undergoes rigorous purification to eliminate trace metals, halides, and sulfur compounds, delivering consistent performance in glass manufacturing and ceramic formulations. The powder’s fine particle size distribution ensures homogeneous mixing with sample matrices, reducing segregation during fusion processes. Compatible with platinum crucibles, it minimizes corrosion risks while providing a clear, bubble-free melt essential for accurate quantitative analysis.
FAQs
1. What is the melting point of this lithium tetraborate grade?
The Puratronic-grade lithium tetraborate melts at approximately 917°C, making it suitable for high-temperature fusion applications without premature decomposition.
2. Can this be used with platinum labware?
Yes, this ultra-pure grade is compatible with platinum crucibles and dishes, as it contains negligible levels of corrosive impurities that could damage noble metal surfaces.
3. How does this differ from standard lithium tetraborate?
The Puratronic grade undergoes additional purification steps to achieve 99.998% purity, eliminating trace metals (Fe, Al, Si) and anions (Cl⁻, SO₄²⁻) that standard grades may contain.
4. What precautions are needed for storage?
Store in a desiccator or sealed container under inert gas to prevent moisture absorption, as the powder is highly hygroscopic and can form hydrates when exposed to ambient humidity.
5. Is this suitable for preparing lithium borate beads?
This grade is specifically optimized for producing clear, homogeneous lithium borate beads in XRF sample preparation due to its low viscosity when molten and minimal crystalline defects.
