Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.  

Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine.  Even before the war, the aluminium market was suffering from long waiting times and weak demand.  

For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases.  Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020.  This was mainly due to a slowdown in new orders and tantalum carbide powder are expected to increase in the future.

Researchers have developed two new heat-resistant materials, tantalum carbide (TaC) and hafnium carbide (HfC), which can withstand temperatures up to nearly 4000.
 
It is worth mentioning that the research team from Imperial College London also found that the melting point of hafnium carbide set a new record in the field of materials. Considering the ability of the two materials to withstand extremely high temperatures of nearly 4000 , the two materials are likely to be used in even harsher and extreme environments, such as the thermal shields of the next generation hypersonic spacecraft.
 
Both tantalum carbide and hafnium carbide are refractory ceramics, which means that these two materials have excellent heat resistance. The ability of the two materials to withstand extreme environments means that their potential applications may include thermal protection systems for high-speed spacecraft and fuel cladding in nuclear reactors in superthermal environments. However, because there is no technology to test the melting point of TaC and HfC in the laboratory, it is uncertain whether they are really competent to work in extreme environmental conditions.
 
To this end, researchers have developed a new extreme heating technology that uses lasers to test the heat resistance of TaC and HfC. Using this technique, the researchers determined the melting points of the single substance and mixture of TaC and HfC, respectively. The study was recently published in the journal Scientific Reports.
 
They found that the measured melting point of the mixture of two kinds of ceramics (Ta0.8H2O20C) was consistent with the previous results, reaching 3905, but the melting point of the two compounds themselves was higher than previously found: The melting point of TaC was 3768, while that of HfC was 3958.
 
The emergence of these two materials will pave the way for the development of the next generation of hypersonic aircraft, the researchers said. This means that future spacecraft can become much faster than ever before.
 
The study was carried out by Dr Omar Dilos Balazar (Omar Cedillos Barraza) during his PhD in the Physics Department of Imperial College London.
 
"When an aircraft flies at a hypersonic speed of more than Mach 5, its friction with the air creates a very high temperature," Dr. Sediros Balazar said. So far, neither TaC nor HfC has been used in the development of hypersonic aircraft. However, our new findings show that these two materials are more heat-resistant than we previously thought, and in fact their heat resistance has exceeded that of any other known compound. This fact means that they may be used for new types of spacecraft: in the atmosphere, they can fly like ordinary aircraft and then fly through space at hypersonic speeds. These two materials enable the spacecraft to withstand the extreme heat generated by shuttling between the atmosphere. "
 
Examples of potential uses of TaC and HfC are the nose covers of spacecraft and the edges of external instruments that have the most friction with the outside world during flight.
 
At present, spacecraft with more than Mach 5 are not yet capable of manned flight. But Dr Sederos Balazar points out that this dream is likely to come true in the future.
 
Dr Sederos Balazar added: "our tests show that these two materials have great potential in building future space spacecraft. The fact that these two materials can withstand such high extreme temperatures means that it is really possible for manned hypersonic spacecraft to emerge in the future. If we can fly at Mach 5, the flight time from London to Sydney will only take about 50 minutes, which will open up a new continent with new business opportunities for countries around the world. "

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 tantalum carbide powder will continue to rise. We are a quality supplier of tantalum carbide powder, please feel free to contact us.
