Zirconium Ceramic is a silver metal with a density of 6.5 g/cm3. Zr has a very small neutron absorption cross-section and a relatively high melting point (1855 °C or 3371 °F), making zirconium a great material for nuclear power rods. In the 1990s, about 90% of zirconium produced every year was consumed by the nuclear industry. However, as more and more people get familiar with Zr and its compound, more applications have been found. Zirconium metal and Zirconium alloys have advantages in specialized chemical environments - primarily acetic and hydrochloric acids. The corrosion resistance of Zirconium comes from a tightly adhered oxide that forms almost instantaneously. As a result, zirconium has been used to make electrode components, foils, flanges bolts, tubes, and rods for special applications. Zirconium products also have wide applications in medical equipment, such as zirconium implants. As Zirconium sheets have better mechanical strength under high temperature, it is also used as support and structure components for high-temperature applications.
We specialize in producing Zirconium Ceramic(Zr 702, Zr 704, Zr 705, Zircaloy-2 and Zircaloy-4) as plates in various thicknesses and sizes. Most plates are cast for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thicknesses start at 0.25" for all metals. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation.
We are experienced in producing custom compositions for commercial and research applications and for new proprietary technologies. We also cast any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Zirconium as rods, powder and plates. Other shapes are available by request.
