“…28) The sinterability, wetting, flowability, crystallization, and the resulting properties of the 60SnO10MgO30P 2 O 5 (mole%) glass powder have also been investigated. 29), 30) Although phosphate sealing glasses can provide adequate flow at the sealing temperature, their coefficients of thermal expansion (CTE, up to > 180 © 10 ¹7 K ¹1 5), 6) ) are too high to match several low-CTE materials such as silicon. The CTE value of SnO MgOP 2 O 5 glasses is in the range of 90150 © 10 ¹7 K…”

“…According to chemical analysis, the composition of the asquenched glass contains around 1.4 mole% Al 2 O 3 which comes from alumina crucible. 29) The dried frits were crushed in an alumina-lined mortar grinder (model RMO, F. Kurt Retsch GmbH & Co. KG, Haan, Germany), then were sieved to obtain a glass powder with particle sizes between 37 and 44¯m.…”

“…With the aid of EDS analysis, layer A is composed of Mg, P, O, and Sn (minor), while the elongated phase is composed of Sn, P, and O. According to the previous study on sintering and crystallization of SnOMgOP 2 O 5 glass of the same composition, 29) a magnesium phosphate Mg 3 (PO 4 ) 2 (denoted as M 3 P) and a stannous phosphate Sn 3 (PO 4 ) 2 (denoted as S 3 P) phases are developed. It is suggested that the layer A was formed due to heterogeneous crystallization of M 3 P phase within the SMP glass along the SMP-CMP interface.…”

“…Also noted is that the cell size is close to the original size of the SMP glass particles (3744¯m). It is suggested that when the sample was heated to temperatures higher than the softening point (corresponding to viscosity value of 10 7.65 poise) of SMP glass (357°C 29) ) the glass particles softened, being deformed due to surface tensions and the gravitational force into the observed elongated shape. Moreover, although the original surfaces of the SMP particles have been replaced by particleparticle interfaces after densification, the abundant defects on the original surfaces would provide numerous heterogeneous sites for crystal nucleation.…”

The coefficients of thermal expansion (CTE) of low-viscosity phosphate sealing glasses are too high to match low-CTE materials such as silicon. In this study, a low-viscosity SnOMgOP 2 O 5 (SMP) glass powder was mixed with 15 vol % of a negative thermal expansion cobalt-magnesium pyrophosphate (Co 0.5 Mg 0.5 ) 2 P 2 O 7 (CMP) ceramic filler to reduce the thermal expansion of the sealing material. The influences of the addition of CMP filler and the CMP particle size on the sintering, crystallization, and the resulting properties of the CMP-filled SMP composites were investigated. It was discovered that the decrease in CMP particle size decreases the effectiveness of CTE reduction of the sintered composites, the crystallization tendency of SMP glass, the softening temperature of the sintered composites, and the resistance to flow above the softening temperature.

Sodium zinc phosphate glasses modified by Tl2O addition of composition Na2−xTlxZnP2O7 (x = 0, 0.005, 0.01, and 0.015) are synthesized following the melt quenching technique. The structure of the glass samples is analyzed by the Fourier transform infrared absorption spectroscopy. The results suggest that the phosphate network is polymerized by the addition of Tl+ ions. The electrical conductivity, electric modulus, and dielectric constant characteristics of the glasses are measured over a wide continuous frequency range of 10−2 Hz–1 MHz and in the temperature range 293–473 K by the impedance spectroscopic method. The ac conductivity data are analyzed following the power law exponent (S) and the proposed correlated barrier hopping mechanism (CBH) is the most suitable conduction mechanism in the studied compositions. The electrical modulus formalism is applied to analyze the electric data to study their dielectric relaxation. Non‐Debye type relaxation is obtained. From the obtained results, the present glass can be used as a high‐energy capacitor.
