Abstract

A general equation describing the rotation of an optical indicatrix of tetragonal crystals (4, 4¯, 4/m symmetry classes) around the X3 axis (optical axis) depending on the direction of uniaxial pressure in the plane perpendicular to crystal optical axis is written. Partial cases of the general equation, when pressure is acting along the X1 (X2) axis or along the diagonal between the X1 and X2 axes, are received. The values of piezo-optic coefficients (POCs) ?61, ?16, and ?45 are determined by the conoscopic method on the basis of the appropriate equations. Other POCs ?im are determined by the interferometric method. All components of the matrix of elasto-optic coefficients are also determined as pin=?imCmn. These results are being compared to the ones received on the basis of wave-mechanical calculations. Objective pin values are necessary to build indicative surfaces of the elasto-optic effect and to find maximums of these surfaces and appropriate maximum values of acousto-optic quality coefficients.

Calcium

See more Calcium products. Calcium (atomic symbol: Ca, atomic number: 20) is a Block S, Group 2, Period 4 element with an atomic weight of 40.078. The number of electrons in each of Calcium's shells is [2, 8, 8, 2] and its electron configuration is [Ar]4s2. Calcium Bohr ModelThe calcium atom has a radius of 197 pm and a Van der Waals radius of 231 pm. Calcium was discovered and first isolated by Sir Humphrey Davy in 1808. It is the fifth most abundant element in the earth's crust and can be found in minerals such as dolomite, gypsum, plagioclases, amphiboles, pyroxenes and garnets. In its elemental form, calcium has a dull gray-silver appearance. Calcium is a reactive, soft metal that is a member of the alkaline earth elements. Elemental CalciumIt frequently serves as an alloying agent for other metals like aluminum and beryllium, and industrial materials like cement and mortar are composed of calcium compounds like calcium carbonate. It is also an biologically essential substance found in teeth, bones, and shells. The name "calcium" originates from the Latin word "calics," meaning lime.

Tungsten

The number of electrons in each of tungsten's shells is [2, 8, 18, 32, 12, 2] and its electron configuration is [Xe] 4f14 5d4 6s2. Tungsten Bohr ModelThe tungsten atom has a radius of 139 pm and a Van der Waals radius of 210 pm. Tungsten was discovered by Torbern Bergman in 1781 and first isolated by Juan José Elhuyar and Fausto Elhuyar in 1783. In its elemental form, tungsten has a grayish white, lustrous appearance. Elemental TungstenTungsten has the highest melting point of all the metallic elements and a density comparable to that or uranium or gold and about 1.7 times that of lead. Tungsten alloys are often used to make filaments and targets of x-ray tubes. It is found in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4]. In reference to its density, Tungsten gets its name from the Swedish words tung and sten, meaning heavy stone.
