What is Aluminum Nitride Used For?

A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.  

The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.  

Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.  

The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.  

The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.  

Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.  

The prices of other commodities like the AlN powder are also expected to be influenced.

Aluminum Nitride Applications
Due to the piezoelectric properties of aluminum nitride, epitaxially grown thin films of crystalline Aluminum nitride are used for surface acoustic sensors (SAW) deposited on silicon wafers. One application is an RF filter, widely used in mobile phones, called a thin-film bulk acoustic resonator (FBAR). This is a MEMS device that uses aluminum nitride sandwiched between two metal layers.
AlN is also used to construct piezoelectric micromechanical ultrasonic transducers that emit and receive an ultrasound and can be used for aerial ranging at distances up to one meter.
Metallization allows AlN to be used in electronic applications similar to alumina and beryllium oxide. AlN nanotubes, as inorganic quasi-one-dimensional nanotubes, with isoelectronic carbon nanotubes, have been proposed as chemical sensors for toxic gases. 
Currently, there is a lot of research into the development of light-emitting diodes (LEDs) that operate under ULTRAVIOLET light using gallium nitride-based semiconductors. Using aluminum gallium nitride alloys, wavelengths as short as 250 nm have been achieved.  In 2006, inefficient AlN LED emission at 210 nm was reported. 
 
AlN application industries include: 
Photoelectric,
Dielectric layer in an optical storage medium, 
The electronic substrate, chip carrier that needs a high thermal conductivity, 
Military,
As a crucible for growing gallium arsenide crystals, 
Steel and semiconductor manufacturing. 


 

Aluminum Nitride Difficulties
At present, aluminum nitride also has some problems.
First, the powder is easy to form aluminum hydroxide with a hydroxy group in the wet environment, and the alumina layer is formed on the surface of AlN powder. The alumina lattice is dissolved into a large amount of oxygen, which reduces its thermal conductivity but also changes its physical and chemical properties, bringing difficulties to the application of AlN powder. The inhibition of hydrolysis treatment of AlN powder is mainly to coat the surface of AlN particles with a substance using a chemical bond or physical adsorption to isolate them from water, to avoid the occurrence of a hydrolysis reaction. At present, the main methods of inhibiting hydrolysis treatment are surface chemical modification and surface physical coating. 
 
Second, the high price of aluminum nitride limits its application to a certain extent.  The preparation of aluminum nitride powder generally requires a high temperature, which leads to high energy consumption in the process of production and preparation, and at the same time, there are safety risks, which is also the main drawback that some high-temperature preparation methods cannot achieve industrial production. Moreover, the impurities in the process of production preparation added to the production of harmful products or problems, such as excessive carbon reduction reaction carbide powder removal problems, as well as the chemical vapor deposition method of by-product hydrogen chloride removal problems, which require the preparation of aluminum nitride for reaction products in the process of the purification, it also led to the preparation of aluminum nitride production cost is high. 
 

Aluminum Nitride Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.

It is used in various high-tech fields, so the market demand for AlN powder will continue to rise. We are a quality supplier of AlN powder, please feel free to contact us.
