To determine whether there is asbestos in talc is usually a combination of polarizing or electron microscopy and X-ray diffraction, and the quantitative analysis of asbestos mainly uses X-ray diffraction method.

Most drugs exist in the form of crystals, using X-ray diffraction, we can obtain the diffraction information of drug characteristics for each different crystal type.

Dandong Tongda Technology Co., LTD., with professional technology and perfect service, has won the trust of scientific research workers around the world.

XRD technology is widely used in the fields of crystallography, physics and metallurgy, including qualitative and quantitative, crystal structure, mechanical analysis, etc. This paper mainly lists its application in polymer research.

The application of XRD in the refractory industry involves all aspects of refractory production. From raw material quality inspection, production process control to product quality inspection.

Micro-xrd can analyze the original state of the sample and carry out phase analysis of various parts of the sample. In this paper, a geological sample lapis Lazuli is taken as an example to further illustrate the effect of micro-diffraction.

Almost all analytical laboratories supporting the pharmaceutical industry have both thermal analysis instruments and X-ray powder diffractometers. Combining DSC and XRD into one simultaneous measurement, thermal data and diffraction data on the same sample can obtain rich information.

With the development of XRD detection technology, instrument miniaturization, low energy consumption, simple use, intelligent detection is becoming more and more popular, and has become the trend of instrument update.

HRXRD is a powerful non-destructive testing method, and its research objects are mainly single crystal materials, single crystal epitaxial thin film materials and various low-dimensional semiconductor heterostructures.

The power conditions depend on the X-ray tube as the target material and focus type. Although Cu targets are widely used for diffraction, the use of Cu targets for residual austenite analysis is not recommended because of the strong fluorescence of iron-based materials.

Asbestos, also known as "asbestos", refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal erosion, electrical insulation and spinnability. The three most common types are chrysotile, iron and cyanite.

In the process of drug development, the properties and structure of drug crystal powders play a crucial role in their efficacy and safety, and the application of X-ray diffraction (XRD) technology provides us with a powerful tool.
