Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as the raw material of additives and the raw material of daily chemical products.

Development of spectrum-energy spectrum composite X-ray fluorescence spectrometer
On March 11, 2019, the national major scientific instrument development project titled "Spectrum-Energy Spectrum X-ray Fluorescence Spectrometer" — led by the National Geological Experimental Testing Center under the Ministry of Natural Resources — successfully passed the comprehensive acceptance inspection organized by the Science and Technology Evaluation Center of the Ministry of Science and Technology. The evaluation was conducted on behalf of the Department of Resource Allocation and Management. Representatives from the Ministry of Science and Technology, the Ministry of Natural Resources, project units, and management personnel were all present during the review process.
The project, which focused on the development and industrialization of a spectral-energy spectrum X-ray fluorescence spectrometer, involved multiple key institutions including the Steel Research Institute Technology Co., Ltd., Beijing Jinzi Tianzheng Intelligent Control Co., Ltd., the Shanghai Institute of Silicate Materials, the Nanjing Geological Survey Center, and several other leading research institutes. These organizations collaborated on the design, core component development, software systems, and application methods for the device.
Over five years of dedicated effort, the team successfully developed the CNX-808 XRF spectrometer — a high-performance, multi-functional instrument capable of spectral, energy spectrum, and elemental distribution analysis. They also created an expert system for qualitative and quantitative analysis, along with a comprehensive set of application methods. The project secured 23 invention patents, 9 of which were authorized, as well as 17 utility model and design patents. In addition, nine work instructions, eight user application certificates, and one open sample database were established. Sixteen new analytical methods were developed, and two national standards and one industry standard were completed and implemented.
The project also resulted in 51 academic papers published in core journals (including 6 EI and 2 SCI), and the first drafts of two monographs on the history of Chinese X-ray spectroscopy technology and its literature index. The integration of spectrum and energy spectrum technologies significantly improved regional scanning efficiency, achieving a “two-spectrum combination with three functions.†All performance metrics met or exceeded the project’s requirements, and the project successfully passed technical and financial reviews in April and October 2018, paving the way for full-scale acceptance.
The CNX-808 XRF spectrometer has reached international standards in X-ray fluorescence technology, breaking foreign monopolies and achieving high-end localization. It now possesses independent intellectual property rights, laying a strong foundation for future instrument development and meeting the growing demand for inorganic element analysis in China’s economic and technological sectors.
