The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. Electron Configuration and Oxidation States of StrontiumĮlectron configuration of Strontium is 5s2. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.The name Silicon originates from the Latin word silex which means flint or hard stone.Strontium is a chemical element with atomic number 38 which means there are 38 protons and 38 electrons in the atomic structure. Silica (or silicon dioxide), as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. The metalloid is rarely found in pure crystal form and is usually produced from the iron-silicon alloy ferrosilicon. Silicon makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, exceeded only by oxygen. Silicon was discovered and first isolated by Jöns Jacob Berzelius in 1823. The silicon atom has a radius of 111 pm and a Van der Waals radius of 210 pm. The number of electrons in each of Silicon's shells is 2, 8, 4 and its electron configuration is 3s 2 3p 2.
Silicon (atomic symbol: Si, atomic number: 14) is a Block P, Group 14, Period 3 element with an atomic weight of 28.085. Strontium was named after the Scottish town where it was discovered. In nature, most strontium is found in celestite (as strontium sulfate) and strontianite (as strontium carbonate). Radioactive isotopes of strontium have been used in radioisotope thermoelectric generators (RTGs) and for certain cancer treatments.
Cathode ray tubes in televisions are made of strontium, which are becoming increasingly displaced by other display technologies pyrotechnics and fireworks employ strontium salts to achieve a bright red color. In its elemental form, strontium is a soft, silvery white metallic solid that quickly turns yellow when exposed to air. Strontium was discovered by William Cruickshank in 1787 and first isolated by Humphry Davy in 1808. The strontium atom has a radius of 215 pm and a Van der Waals radius of 249 pm. The number of electrons in each of Strontium's shells is and its electron configuration is 5s 2. Strontium (atomic symbol: Sr, atomic number: 38) is a Block S, Group 2, Period 5 element with an atomic weight of 87.62. Please request a quote above for more information on lead time and pricing. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies.
Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). Rotary (cylindrical), round, rectangular, square, ring, annular, oval, "dog-bone" and other shaped targets are available in standard, custom, and research sized dimensions. Our standard sputtering targets for thin film deposition are available monoblock or bonded with planar target dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devices as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications. Thin Film Deposition & Evaporation MaterialsĪmerican Elements specializes in producing high purity Sodium Strontium Silicate Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications.Additive Manufacturing & 3D Printing Materials.
