Union of niobium with diamond can be used in civil construction, pavements, metallurgical industries, plants and more, due to its high performance, durability and solidity.
New technology produced from diamond and niobium powder, with a high degree of hardness, resistance and non-toxic properties, is a new product that promises greater innovation and efficiency for civil construction and the oil industry in Brazil and around the world.
The innovative project, with a high degree of hardness, resistant and non-toxic, to be used in the oil industry and civil construction, was developed by the scholarship holder of the Coordination for the Improvement of Higher Education Personnel (CAPES) Meysam Mashhadikarimi, for his doctorate from the Postgraduate Program in Materials Science and Engineering at the Federal University of Rio Grande do Norte (UFRN).
Technology can be used in civil construction, pavements, metallurgical industries, plants, bridges and other structures
The technology that promises to revolutionize civil and oil construction can be used in the renovation of road pavements, airport runways, modernization of metallurgical industries, nuclear plants, bridges and other structures, due to its high performance, durability and solidity.

Mashhadikarimi explains that his research resulted in the creation of a composite product for making diamond tools, called condensed diamond body, which is the result of the combination of diamond dust and pure niobium.
With characteristics that present greater hardness, this junction results in a compound with lower porosity and greater resistance to wear during its use in civil construction and industry. To achieve this result, it was necessary to find a suitable binding element, which would prevent the diamond from losing its solidity and hardness, becoming more fragile. Studies showed that the use of pure niobium would be ideal for the compound's performance.
Replacing conventional binding elements, such as iron and cobalt, with niobium, reduces the risk of contamination of workers
The mixture of these two substances allows the new material to have unique and valuable characteristics for the construction sector and general industry. “The diamond body sintered with pure niobium binder has no porosity and greater hardness, factors that, together, result in greater resistance to wear,” he explains. The new technology can be used to renovate roads and airport runways, modernize metallurgical plants, nuclear plants, bridges and other structures, due to its characteristics.
“We replaced cobalt with niobium with the aim of reducing failures and increasing its useful life”, said Meysam Mashhadikarimi, PhD in Materials Science and Engineering from UFRN. Furthermore, the replacement of conventional binding elements, such as iron and cobalt, with niobium, reduces the risk of contamination for construction and industrial workers when using machines, as the material is non-toxic.
The work has already been patented and has had its industrial application recognized, providing greater quality for infrastructure, civil construction and industry in possible future projects.
