Systematization of Simple and Binary Silicates According to Relationship “Composition– Structure–Property”

Abstract

It is shown that acentric silicate crystals are positioned into three intersected ellipses of «acentricity» on the plane of the oxide bond lengths plane. The dependence of nonlinear optical property of silicates on the shortest chemical bond length L(Si-O) is non-monotonous. The suggested crystal chemistry analysis is useful for searching new acentric silicate crystals.

Comparison of the acentric properties for the oxide crystals

“…These crystal properties are of the utmost interest for acentric dielectronics [3,[7][8][9][10]. The data on the acentric properties values are collected as from reference books, both from our papers, contained many tabulated data abo-ut interrelationship «composition -structure-property» for oxide crystals [3,[6][7][8][9][10][11][12][13][14]. These data are quite enough that in first approximation compare mutually all acentric properties.…”

Comparative Interrelationship of the Structural, Nonlinear-Optical and Other Acentric Properties for Oxide, Borate and Carbonate Crystals

“…Earlier, in our contributions, the key empiric interrelationship "composition-oxide bond length-structure" was particularly discussed for many binary and ternary oxide crystals: carbonates, borates, phosphates, silicates, germanates, vanadates, molybdates, wolframates, iodates, niobates, titanates, tantalates, zincates [11,39,40,42,43,45,[49][50][51][53][54][55][56]. In reference book [6] 3 , and among perspective crystals-8 simple and binary borates, and two fluoride borates.…”

“…These distributions are dependent on the nature of chemical bonds in different crystals and, consequently-on the classes of chemical compounds [38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56].…”
