What is terbium used for commercially?

This passage showcased the topic “What is terbium used for commercially” with related information about terbium. It provided basic information about terbium, explained what terbium is, what the specific features of terbium are, what the commonly known compounds related to terbium are, and of course, what is terbium used for commercially. Through this passage, you could have a general knowledge about terbium, before getting to know what is terbium used for commercially.

How do you know about terbium?

Before getting to know what is terbium used for, let’s have a general impression of this chemical element terbium.

Basic information about terbium

With the symbol Tb, terbium is one of the chemical elements from the element periodic table. It is in the f block with no number and in period 6. Neighboring Tb in the same group is berkelium below, while alongside Tb in the same period are gadolinium and dysprosium. The distribution of electrons of terbium is 4f9 6s2, and the number of electrons for each shell is 2, 8, 18, 27, 8, 2.

Specific properties of terbium

The physical appearance of terbium is shiny and silvery. Moreover, it is tensile enough to be drawn without breaking and soft enough to be cut with sharp objects. The allotropes of terbium are that it could stay at 2 crystal form at 1289 °C, and the structure would be hexagonal close-packed. When it reaches 1629 K (1356 °C) it could start to melt, while when it reaches 3396 K (3123 °C) it would boil. In solid form, it is quite dense, with 8.23g per cm², while in liquid form the density will decrease slightly to 7.65 per cm². It requires 10.1 KJ/mol of heat for fusion and 391 kJ/mol of heat for vaporization.

At room temperature, the speed of transmitting sound for terbium is 2620 m/s, the conductivity of warmth is 11.1 W/(m⋅K), and it expands by warmth as 10.3 µm/(m⋅K). The electrical conductivity is 1.150 µΩ⋅m.

Compounds of terbium

Terbium is relatively stable, it is often found in isotopes from nature. There are 36 radioisotopes, the most common one is terbium-159.

There are so many terbium compounds, for example, TbH₂, TbH₃, TbB₂, Tb2S₃, TbSe, TbTe and TbN. Moreover, terbium could form terbium(IV) fluoride, the only halide. There are other formulas like Tb⁺⁴, Tb⁺³. It could be seen that isotopes are much more common for terbium.

What is terbium used for commercially

For isotopes, terbium is used to stabilize the fuel cells in the process of calcium fluoride, calcium tungstate, and strontium molybdate. Besides, terbium could be found in the production of electronic devices like actuators, oceanic sonar systems, all kinds of sensors, bugging devices, and alloys, with or without magnetostriction. Due to its magnetostriction nature, terbium is applied in those speaker systems.

For those compounds, there is terbium oxide, which is used in screens and monitors for its luminescence nature, as well as applied in scintillation sensors, white LEDs, luminous paints, and fluorescent lights. Moreover, it is used in oxygen sensing, postage stamps, radio-luminescence, cathode-ray tubes, and color television CRTs.

Therefore, it is obvious that terbium is very commonly used commercially. Daily electrical products like lights, monitors, and screens all contain the element Tb for the luminescence. Besides, not very common uses exist as well. Lasers, semiconductors, solid-state devices, and stabilizers of fuel cells.

Furthermore, terbium isotopes are used in cancer treatments as well. Targeted radiotherapy using alpha particles. Tb is also used for imaging and online monitoring for gamma camera distribution.

Effects on human and environment

In powder form, terbium is very irritating and mildly toxic to the human body, however, there is currently no research on how toxic it is to humans.

Besides, it seems there are no environmental effects so far for terbium.

Conclusion:

From this passage, it is concluded that terbium is used in various uses commercially. Besides introducing those applications of terbium, this passage went through details of this chemical element, showcasing its specific properties about its features, physical appearance, and chemical features therefore back to the question “What is terbium used for commercially ”. According to its nature, it seems there are few commercial uses for far for terbium. Research would be more common.
