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.

X-ray diffractometer is a device that uses the principle of interaction between X-rays and substances to obtain information such as crystal structure and lattice constant of substances by measuring the diffraction Angle and intensity of X-rays in substances.

Today we are going to talk about the protagonist - powder diffractometer. It is an important product of Dandong Tongda Technology Co., Ltd. and one of the indispensable equipment in the laboratory.

Cement is a common building supplies, generally divided into ordinary Portland cement, Portland cement mixed materials and special cement, the use of Portland cement is more.

This paper mainly analyzes the cause of a black spot phenomenon on the negative surface of lithium iron phosphate battery.

As a means of characterizing crystal structure and its change rule, XRD is widely used in many fields such as materials, chemistry, ceramics, metallurgy and minerals.

The three-dimensional space of atoms is arranged in a long-range order, and the smallest unit of repeated arrangement is called the cell, which can be divided into 7 kinds of crystal systems, 14 kinds of lattice, and 230 kinds of space groups according to the arrangement law.
