Typical Applications:

At present, the main uses of holmium are as follows:

Metal halide lamp is a kind of gas discharge lamp, which is developed on the basis of high pressure mercury lamp. It is characterized by filling various rare earth halides in the bulb. At present, rare earth iodide is mainly used, which emits different spectral line colors in gas discharge. The working material used in holmium lamp is holmium iodide, which can obtain higher metal atom concentration in the arc region, thus greatly improving the radiation efficiency.

Holmium can also be used as an additive of yttrium iron or yttrium aluminum garnet. Holmium doped yttrium aluminum garnet (Ho:YAG) can emit 2 µm lasers. The absorption rate of human tissue to 2 µm lasers is high, almost three orders of magnitude higher than that of HD:YAG. Therefore, when used for medical operation, the Ho:YAG laser can not only improve the operation efficiency and accuracy, but also reduce the thermal damage area. The free beam generated by the holmium crystal can eliminate fat without producing excessive heat, thus reducing the thermal damage to healthy tissues. It is reported that holmium laser treatment of glaucoma in the United States can reduce the pain of patients undergoing surgery.

A small amount of holmium can also be added to terfenol-D magnetostrictive alloys to reduce the field required for saturation magnetization.

In addition, optical communication devices such as fiber lasers, fiber amplifiers and fiber sensors can be made by using holmium doped fibers, which will play a more important role in today’s rapid development of optical communication.

Inquiries and orders should include the following information:

1. Quantity
2. Purity

Standard Packing:

Packed in sealed bags and bottles. Special package is available on request.

Storage:

The storage method of a substance is directly related to the physical and chemical properties of the substance. When storing rare earth products in laboratories or enterprises, the following eight principles should be followed.

1. The principle of sealing. Most rare earth products must be sealed, which is an important principle for product preservation. It mainly applies products with the following properties: products that are easily deliquescent, reagents that are easy to react with water vapor, and reagents that are easy to be oxidized or reduced.
2. The principle of avoiding light. For rare earth products that are easily decomposed by exposure to light or heat, avoid sunlight and store them in a cool place.
3. The principle of isolation. Rare earth products should be kept away from fire sources, and strong oxidants should be kept separate from easily oxidized substances.
4. The principle of ventilation. The storage of most rare earth products must follow this principle, especially strong oxidants.
5. Low temperature principle. Too high temperature will easily decompose the product, especially when the weather is hot in summer. Cooling treatment can be carried out if necessary.
