Zirconium Boride is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Zirconium is a Block D, Group 4, Period 5 element. The number of electrons in each of Zirconium's shells is 2, 8, 18, 10, 2 and its electronic configuration is [Kr] 4d2 5s2. In its elemental form zirconium's CAS number is 7440-67-7. The zirconium atom has a radius of 159.pm and it's Van der Waals radius is 200.pm. Zirconium is non-toxic. Zirconium is primarily used in it's oxide or zirconia form. Zirconium dioxide has a high melting point (2,700° C) and a low thermal conductivity. Its polymorphism, however, restricts its widespread use in ceramic industry. During a heating process, zirconia will undergo a phase transformation process. The change in volume associated with this transformation makes the usage of pure zirconia in many applications impossible. Addition of some oxides, such as CaO, MgO, and Y2O3, into the zirconia structure in a certain degree results in a solid solution, which is a cubic form and has no phase transformation during heating and cooling. This solid solution material is termed as stabilized zirconia, a valuable refractory. Stabilized zirconia is used as a grinding media and engineering ceramics due to its increased hardness and high thermal shock resistivity. Stabilized zirconia is also used in applications such as oxygen sensors and solid oxide fuel cells due to its high oxygen ion conductivity.Zirconium was first discovered by William Gregor in 1791. The name Zirconium originated from the Persian word 'zargun' meaning gold color or gold-like. See Zirconium research below.
Boron is a Block P, Group 13, Period 2 element. The number of electrons in each of Boron's shells is 2, 3 and its electronic configuration is [He] 2s2 2p1. In its elemental form boron's CAS number is 7440-42-8. The boron atom has a radius of 79.5.pm and it's Van der Waals radius is 200.pm. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. Optical characteristics include transmitting portions of the infrared. Boron is a poor conductor of electricity at room temperature but a good conductor at high temperature. Boron in its elemental form is not toxic. Amorphous boron is used in pyrotechnic flares to provide a distinctive green color, and in rockets as an igniter Boric acid is also an important boron compound with major markets in textile products. Boron compounds are also extensively used in the manufacture of borosilicate glasses. The isotope Boron-10 is used as a control for nuclear reactors, as a shield for nuclear radiation, and in instruments used for detecting neutrons. Boron nitride has remarkable properties and can be used to make a material as hard as diamond. The nitride also behaves like an electrical insulator but conducts heat like a metal. Boron also has lubricating properties similar to graphite. Boron was first discovered by Sir Humphry Davy and J.L Gay-Lussac in 1808. The name Boron originates from a combination of carbon and the Arabic word 'buraqu meaning borax. See Boron research below.
