Precious Metal Catalyst

Precious metal catalysts are a type of catalytic material that use precious metals as the active component and are used to support chemical reactions or increase the rate of chemical reactions. Commonly used precious metals include platinum, palladium, rhodium, silver, ruthenium, etc., among which the most commonly used are platinum and rhodium. XRD is a highly effective catalyst characterization technology and has important applications in precious metal catalyst research. It can help researchers understand the crystal structure, phase transformation, crystallographic properties, etc., of the catalyst, revealing the performance and activity of the catalyst.

Cement Composition

The quality of cement primarily depends on the mineral composition and structure of the clinker. The use of XRD to directly and quantitatively test the mineral phases of Portland cement clinker can further clarify the relationship between strength and mineral content, improving the level of cement quality control. Accurate measurement of the mineral composition not only provides a deeper understanding of the influence of raw material properties on clinker formation but also determines the effect of the kiln atmosphere and the heating process on the clinker formation process.

Asbestos Analysis

There are many methods available for asbestos testing. Since the environment where asbestos occurs, the purpose of the assessment, and the chosen methods vary, a single test cannot address all issues. The detection efficiency and accuracy can only be guaranteed by combining these methods. XRD, PLM, SEM, FTIR, and other instruments are mostly used for qualitative and quantitative analysis of asbestos. The testing principle of the X-ray diffractometer (XRD) is that each mineral has a unique X-ray diffraction pattern and data. The intensity of the diffraction peak is proportional to its content, which can be used to determine whether a sample contains specific asbestos minerals, identify the type of asbestos, and quantify its content.

Crystallinity of Polymer Plastics

Polymeric materials have a wide range of applications in every aspect of modern society, from packaging materials to aerospace engineering, and possess different properties for different purposes. The Degree of Crystallinity (DOC) is a key index affecting the properties of polymeric materials, and changes in crystallinity influence various characteristics such as mechanical properties, thermal properties, density, and optical properties of polymers. Therefore, controlling the crystallinity of polymeric materials is an important factor in materials engineering.

In general, methods for measuring crystallinity include density methods, calorimetry, NMR, IR, and XRD. Among these, X-ray diffraction is considered a more comprehensive and intuitive technique for analyzing polymer structure, providing clearer data and being more widely used. Common methods for determining the crystallinity of polymers using X-ray diffraction include mapping, regression lines, the Ruland method, and partial peak fitting of X-ray diffraction curves. Additionally, X-ray diffraction can also be used to analyze the polymorphism, grain size, and structure of polymeric materials.

Calcined Alumina Crystal Form Conversion Rate

Al₂O₃ has many isomorphic crystals, with more than ten currently known. Different structures result in different properties of these isomorphic crystals. There are three main crystal forms in use: α-Al₂O₃, β-Al₂O₃, and γ-Al₂O₃. In the performance testing of α-Al₂O₃, one of the more important technical indicators is the α-phase transformation ratio. The α-phase transformation ratio represents the proportion of the α-phase in alumina products. Currently, both domestically and internationally, the α-phase transformation ratio of alumina is measured using the X-ray diffraction method.

Soft Magnetic Iron

Soft magnetic iron oxide is an important soft magnetic material with a wide range of applications across electronics, communications, medicine, automotive, and industrial sectors. For example, in the electronics and communications industries, it is commonly used in the production of components such as transformers, inductors, filters, and sensors.

The crystal structure of soft magnetic iron oxide plays a critical and determining role in its performance. Analyses and studies conducted on soft magnetic iron oxide using XRD technology can reveal the material’s microstructure and properties, providing an essential theoretical foundation for improving its applications and performance.

Titanium Dioxide Rutile Conversion Rate

Controlling the lattice type and lattice ratio in titanium dioxide is of practical importance, as these factors have a significant impact on the quality of products in downstream applications such as coatings and plastics. X-ray diffractometers are widely used instruments for phase analysis of materials. Different materials have different structures and thus exhibit distinct diffraction spectra. Today, the lattice type of a material can be determined based on the characterized diffraction spectral lines of its crystal structure, while the crystal form of the material can be analyzed based on the peak intensities of the characterized diffraction peaks.
