Why Choose BS ISO 23071:2021?

The BS ISO 23071:2021 standard is a vital tool for anyone involved in the production, testing, or research of refractory products. Refractories are materials that are resistant to high temperatures and are used in a variety of industrial applications, including furnaces, kilns, incinerators, and reactors. The presence of carbon in these materials can significantly affect their performance, making it crucial to accurately determine the reduced species present.

This standard provides a detailed procedure for using X-ray diffraction (XRD) to identify and quantify reduced species in carbon-containing refractories. XRD is a powerful analytical technique that allows for the precise characterization of crystalline materials, making it ideal for this application. By following the guidelines set out in BS ISO 23071:2021, users can ensure that their analyses are accurate, repeatable, and in line with international best practices.

Benefits of Using XRD for Refractory Analysis

X-ray diffraction is a non-destructive technique that provides detailed information about the crystallographic structure, chemical composition, and physical properties of materials. When applied to carbon-containing refractories, XRD offers several advantages:

• Precision: XRD provides highly accurate measurements, allowing for the precise determination of reduced species in complex refractory matrices.
• Non-destructive: The analysis does not alter the sample, preserving it for further testing or use.
• Comprehensive: XRD can identify a wide range of crystalline phases, providing a complete picture of the material's composition.
• Efficiency: The technique is relatively quick, enabling rapid analysis and decision-making.

Applications of BS ISO 23071:2021

This standard is applicable to a wide range of industries that utilize refractory materials, including:

• Metallurgy: Ensuring the quality and performance of refractories used in metal production and processing.
• Ceramics: Analyzing the composition of kiln linings and other high-temperature ceramic components.

This standard BS ISO 23071:2021 Refractory products. Determination of reduced species in carbon containing refractories by XRD is classified in these ICS categories:

• 81.080 Refractories

This document describes methods for the determination of mineralogical phases often present as additives or reaction products in carbon containing or graphitic refractory products by X-ray Diffraction (XRD) using a Bragg-Brentano diffractometer. It includes details of sample preparation and general principles for qualitative and quantitative analysis of mineralogical phase composition. Quantitative determination of ?-Si₃N₄, ?-Si₃N₄, AlN, aluminium metal, Al₄C₃, silicon metal, boron carbide and BN are described. The problems encountered with some determinations are highlighted.

Additional reduced species present in some refractories could include Al₂O₃?AlN solid solutions (so called Alons), Si₃N₄?SiO₂ solid solutions and Si₃N₄?Al₂O₃ solid solutions (Sialons). The presence of some of these solid solution components will cause problems with both identification and quantification as they are not well-defined structures.
