Diamonds especially lab-grown diamonds are currently being employed in plethora of industrial applications like machining, cutting, thermal management, magnetic field detection, acoustics, drilling, optical (Laser, IR, RF), detectors in high energy physics, waste water treatment, ozone generators, anti-counterfeiting technology etc.. Diamonds are also the chief constituent in oil and gas drilling and exploration, mining, construction, transportation, and electronics. The quality of a lab-grown diamond is of utmost importance that determines a diamond’s usability in the above mentioned applications.
Some of these applications require lab-grown diamonds to be in the form of a block. The block shaped diamonds are usually created by placing a substance with high carbon content in a niobium crucible and then exposed to high pressure and high temperature (HPHT) setting.
H.C. Starck Group – a prominent global supplier of technology metals and advanced ceramics, has made significant improvements to niobium material used in the crucible required for manufacturing diamonds. The quality and surface finish of the niobium crucibles is vital for superior quality of lab-grown diamonds. As result of H.C. Strack’s new innovation, niobium sheets can now be easily deep drawn into crucible with higher flatness and smoothness. A lab-grown diamond produced in a niobium crucible with enhanced flatness and smoothness will require lesser grinding.
Dmitry Shashkov, Member of H.C. Starck’s Executive Board and Head of the Fabricated Products Division recently said “H.C. Starck is positioned as a premier supplier for the rapid growth in the synthetic diamond industry caused by a surge in oil and gas drilling and the deployment of advanced drilling techniques. H.C. Starck’s R&D engineers made significant improvements to our niobium material addressing issues inherent to the manufacture of crucibles for synthetic diamonds, including the deep draw challenges and quality requirements.”
He further added that H.C. Starck is committed to serving the lab-grown diamond industry with their high-performance materials solutions.
