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.

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.
