Spectroscopic, Dielectric and Optical Properties of 60ZnO-30B2O3-10SiO2 Glass-Al2O3 Composites

Abstract

Zinc borosilicate glass (ZBS) with the formula 60ZnO–30B2O3–10SiO2 was prepared by melt‐quenching method and the effect of addition of 0–15 wt% of α‐alumina (Al2O3) on the spectroscopic, dielectric, and optical properties of ZBS has been studied. Structural and microstructural modifications of ZBS with alumina addition were studied using X‐ray diffraction, spectroscopic (Raman and IR) and scanning electron microscopic techniques. The effect of Al2O3 on the photoluminescence properties of ZBS was also investigated.

Structural, electrical and thermal properties of borosilicate glass–alumina composites

“…Borosilicate glasses constitute a family of glasses with a large number of applications, particularly due to their low coefficient of thermal expansion, similar to that of silicon (3.4 Â 10 À6°CÀ1 ) [1], high electrical resistance (10 11 -10 13 X m) [4], low dielectric constant (4.8 at 1 MHz) [5] and to their high resistance to chemical attack [3,5,6]. Due to their low softening temperature (800°C) [7], some borosilicate glasses in the form of powders have particular interest for their use in the production of sintered glasses with controlled porosity [8] and for their application in the manufacture of sintered glass-ceramic composites [3,7,[9][10][11][12][13][14].…”

“…Glass-alumina composites, namely borosilicate glass with alumina, present a large potential as substrate materials for integrated circuits (IC) because they can be densified at low temperatures and present the required electrical and thermal characteristics [1][2][3].…”

Crystallization, sinterability and dielectric properties of CaO–B2O3–SiO2 glass ceramics with Al2O3 additives

“…As an attractive glass-ceramic system, CaO-SiO 2 -B 2 O 3 (CBS) has been investigated as the candidate substrate materials in the electronic packaging filed, because of its low sintering temperature, relatively low dielectric constant (*6.5) and low material cost [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Wang and Zhou [11] studied the effects of the glasses of different compositions, holding time and heating speed on CaO-B 2 O 3 -SiO 2 system.…”

Low temperature sintering and characteristics of K2O–B2O3–SiO2–Al2O3 glass/ceramic composites for LTCC applications

“…Some representative widespread-researched glass system contains: CaO-B 2 O 3 -SiO 2 [8,9], CaO-Al 2 O 3 -SiO 2 [10,11], ZnO-B 2 O 3 -SiO 2 [12], BaO-B 2 O 3 -SiO 2 [13], CaO-Al 2 O 3 -B 2 O 3 -SiO 2 [14], etc. Borosilicate glass possesses the characteristics of low dielectric constant, low dielectric loss [15] and good insulation [16].…”
