Calcium Tetrafluoroborate Hydrate is a highly water insoluble crystalline Calcium source for uses compatible with higher (basic) pH environments. Calcium Tetrafluoroborate Hydrate is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area 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 Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Calcium is a Block S, Group 2, Period 4 element. The number of electrons in each of Calcium's shells is 2, 8, 8, 2 and its electronic configuration is [Ar] 4s2. In its elemental form calcium's CAS number is 7440-70-2. The calcium atom has a radius of 197.4.pm and it's Van der Waals radius is 200.pm. Calcium is a reactive, soft metal. Calcium is a member of the alkaline earth elements. Calcium is an essential metal for living organisms and is non-toxic. Its primary commercial application is in its metallic form as a reducing agent in the production of other metals. In iron and steel production it is added to the melt to remove oxygen, sulfur and carbon. The various calcium compounds have wide application in food, pharmaceutical and cosmetics. It is used in small doses in alloys of copper and beryllium. It is used in dietary supplements and food production because it has been shown to improve bone and dental health. Calcium information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Calcium was first discovered by Sir Humphrey Davy in 1808. The name calcium originates from the Latin word 'calics' meaning lime. See Calcium 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 is not toxic. 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.
