In the field of modern materials science, the performance of inorganic materials often depends on their crystal structure, phase composition, and microstructural characteristics. The FRINGE series desktop X-ray diffractometer (XRD) launched by Suzhou Langsheng Scientific Instrument Co., Ltd. has become an ideal tool for characterizing inorganic materials due to its compact design, high-resolution detector, and intelligent analysis software.
1、 Core functions and advantages of inorganic material testing
The FRINGE series (such as FRINGE EVS, D200, etc.) uses a θ - θ vertical angle measuring instrument, which can achieve rapid analysis of various forms of samples such as powder, block, and film. Its core advantages include:
High precision phase identification：By using the Bragg diffraction principle, the crystal phases in inorganic materials (such as corundum and quartz phases in ceramics) can be accurately identified, with a detection limit of less than 1%.
Crystal structure analysis：Measurement of lattice parameters, cell symmetry, and crystallinity is suitable for evaluating the crystal integrity of positive electrode materials for lithium batteries, such as LiFePO ₄.
Trace impurity detection：Quantitative analysis of metal oxides (such as rutile/rutile phases in TiO ₂) to optimize process purity.
2、 Typical application scenarios
Quality control of ceramic materialsIn advanced ceramic production, FRINGE can quickly analyze the phase composition after sintering, ensuring the proportion of the main crystal phase of β - Si ∝ N ₄ in silicon nitride ceramics and avoiding strength reduction caused by residual alpha phase.
Research and development of lithium battery materialsFor NCM ternary positive electrode materials, residual stress analysis function is used to detect lattice distortion during charge and discharge processes, providing data support for improving cycling stability.
Mineral composition identificationIn geological exploration, FRINGE can directly perform XRD scanning on core powder to distinguish the relative content of coexisting minerals between calcite and dolomite, and guide mineral processing technology.
3、 Convenient operation and intelligence
The CrystalX software installed on the device enables "one click" analysis: users only need to place a sample (such as 0.1g ceramic powder), click "start testing", and obtain a complete report containing phase ratios and grain sizes within 10 minutes. Its desktop level design (with built-in water cooling system, occupying less than 0.5 square meters) can be directly deployed next to the production line to achieve real-time quality inspection.
4、 Conclusion
The Langsheng FRINGE series significantly reduces the threshold for inorganic material structure analysis with high sensitivity, low maintenance costs, and intelligent operation. Whether it is crystal screening in the research and development stage or consistency monitoring of industrial batches, this equipment can provide reliable data support to promote the rapid transformation of inorganic materials from laboratory to industrialization.
