What is THULIUM?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is THULIUMwhich has developed particularly rapidly in recent years. Do you know about THULIUM?

The official answer: Thulium [1] is a silvery-white metal with the element symbol Tm, ductility, and a softer texture that can be cut with a knife; Melting point 1545 °C, boiling point 1947 °C, density 9.3208. Thulium is stable in air; Thulium oxide is a pale green crystal. The atomic number of thulium is 69, the atomic weight is 168.93421, and the name of the element is derived from the name of the country where it was discovered. In 1879, Swedish scientist Clive separated two new elements, thulium and holmium, from erbium soil. The content of thulium in the earth’s crust is 2 parts per 100,000, which is the least abundant element in rare earth elements, found in phosphorus yttrium ore and black rare gold ore, and the natural stable isotope is only thulium 169. used in high-intensity power generation light sources, lasers, high-temperature superconductors and other fields.

What’s the application of THULIUM?

Although thulium is quite rare and expensive, there are still some applications in special fields.
High-intensity discharge light source
Thulium is often introduced into high-intensity discharge light sources in the form of high-purity halides (usually thulium bromide) to use the spectrum of thulium.
laser
Holmium-chromium-thulium-tridounded yttrium aluminum garnet (Ho:Cr:Tm:YAG) is a efficient active laser dielectric material. It emits a laser with a wavelength of 2097 nm and is used in military, medical and meteorological applications. Thulium-mono-doped yttrium aluminum garnet (Tm:YAG) emits lasers with wavelengths between 1930 nm and 2040 nm, which is very effective in ablation on the surface of tissues, making coagulation undrinated in both air and water. This makes thulium lasers very promising for basic laser surgery [3].
X-ray source
Despite the higher cost, portable X-ray equipment containing thulium has begun to be used in large quantities as radiation sources in nuclear reactions. These radiation sources have a service life of about one year and can be used as tools for medical and dental diagnostics, as well as for flaw detection of mechanical and electronic components that are difficult to reach. These radiation sources do not must a lot of radiation protection – only a small amount of lead [4].
Thulium-170 is used in radiation sources for cancer brachytherapy. This isotope has a half-life of 128.6 days and five emission lines of considerable intensity (7.4, 51.354, 52.389, 59.4 and 84.253 kEV). Thulium-170 is also one of the four most used industrial radiation sources.
High temperature superconducting materials
Like yttrium, thulium is also used in high-temperature superconductors. Thulium has potential use value in ferrite: as a ceramic magnetic material used in microwave equipment. Due to its special spectrum, thulium can be applied to arc lamp illumination like scandium, and the green light emitted by arc lamps using thulium is not covered by the emission lines of other elements. Since thulium glows blue under ultraviolet light, thulium is also used as one of the anti-counterfeiting marks in euro banknotes. The blue fluorescent light emitted by the addition of thulium calcium sulfate is used in a personal dosimeter for radiometric dose detection

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
