13760-78-6 Usage
Chemical Properties
Bright-yellow solid. Insoluble in water.
Uses
Different sources of media describe the Uses of 13760-78-6 differently. You can refer to the following data:
1. Holmium(III) fluoride is used as an intermediate in the manufacture of glass, metal halide lamp and dopant to garnet laser. It is employed in metallurgy, chemical and physical vapor deposition and in some optical coatings.
2. Dysprosium is most commonly used as in Neodymium-iron-boron high strength permanent magnets. While it has one of the highest magnetic moments of any of the rare earths (10.6uB), this has not resulted in an ability to perform on its own as a practical alternative to Neodymium compositions.
It is however now an essential additive in NdFeB production. It is also used in special ceramic compositions based on BaTiO formulations.
Dysprosium is used, in conjunction with Vanadium and other elements, in making laser materials and commercial lighting. Nanofibers of Dysprosium compounds have high strength and large surface area. Therefore, they can be used to reinforce other materials and as a catalyst.
Recent research has examined the use of Dysprosium in Dysprosium-iron-garnet (DyFeG) and silicon implanted with Dysprosium and Holmium to form donor centers.
Dysprosium Metal is an important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency. Another most promising use of high purity Dysprosium Metal is in the magnetostrictive alloy TEFENOL-D. There are also other applications for some special master alloys. It is highly susceptible to magnetization, they are employed in various data-storage applications, such as in hard disks.
Check Digit Verification of cas no
The CAS Registry Mumber 13760-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,6 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13760-78:
(7*1)+(6*3)+(5*7)+(4*6)+(3*0)+(2*7)+(1*8)=106
106 % 10 = 6
So 13760-78-6 is a valid CAS Registry Number.

Experimental study of the enthalpy of holmium trifluoride in solid and liquid states
Lyapunov,Baginskii,Stankus
, p. 17 - 20 (2000)
The high temperature enthalpy of high purity HoF3 from 432 to 1588 K was measured by a drop calorimeter method. The temperature dependences of enthalpy and heat capacity were calculated. The values of heat capacity and enthalpy changes on melting were obtained. Original experimental values are presented.

Hydrothermal synthesis of rare-earth fluoride nanocrystals
Wang, Xun,Zhuang, Jing,Peng, Qing,Li, Yadong
, p. 6661 - 6665 (2008/10/09)
In this paper, a hydrothermal synthetic route has been developed to prepare a class of rare-earth fluoride nanocrystals, which have shown gradual changes in growth modes with decreasing ionic radii and may serve as a model system for studying the underlying principle in the controlled growth of rare-earth nanocrystals. Furthermore, we demonstrate the functionalization of these nanocrystals by means of doping, which have shown visible-to-the-naked-eye green up-conversion emissions and may find application in biological labeling fields.
