Custom X-ray Flux Chemicals from XRF Scientific
X-ray fluorescence is a process in which fluorescent x-rays are emitted from a substance which has been excited by gamma rays or X-rays. This process can be used as an analytical procedure which is non-harmful, working to evaluate the chemistry and material composition of a sample. This is an extremely versatile technique which can be beneficial for a broad range of applications to analyze a large number of materials across the periodic table.
How does X-ray Fluorescence Work?
X-ray fluorescence relies on the process of ionization, where an atom gains a positive or negative charge by losing or gaining electrons to create ions. Atoms inside a material can ionize when exposed to short wavelength X-ray beams and gamma rays.
When these are processed, an...
Flux Chemicals for Calcareous Refractory Sample Prep
Calcareous refractories are high-temperature materials mostly composed of calcium carbonate (CaCO3). Owing to the complex reaction mechanics of carbonation, calcareous aggregates make exceptional mortars as they have a positive long-term chemical effect on mortar behaviour. Additionally, calcites exhibit exceptional thermal properties such as melting points in the region of 1330°C (2430°F). These combined thermochemical qualities make calcareous minerals ideal aggregates for refractory concrete.
All industrial materials are subject to some form of quality assurance and control (QA/QC). In this article, we will explore the beneficial properties of calcareous refractories before discussing appropriate flux chemicals for sample preparation and analysis.

Lithium Tetraborate X-ray Flux for Alumina Fusion
Determining the volume of aluminium oxide (Al2O3), or alumina, in clays and silicates can be an arduous task. Gravimetric analysis has been classically applied, but these techniques are both time-consuming and complicated. Samples must first be decomposed using a choice of precipitants before aluminium is separated from interfering elements like iron (Fe) and titanium (Ti). The precipitate is fired to promote oxidation then weighed. This may be expressed as a percentile of overall sample weight or as alumina after ignition.
Why Use X-ray Flux Chemicals for Alumina Fusion?
Various organic reagents are proposed for quantitative precipitation of aluminium, which creates a burden of choice. Additionally, the gravimetric workflow itself is...
