The effect of TiO2 and P2O5 on densification behavior and properties of Anortite-Diopside glass-ceramic substrates

Abstract

In this work the synthesis of anorthite-diopside glass-ceramics (GCs) was carried out via sintering and crystallization of glass powder compacts in the temperature interval 800°C and 950°C. Glass powder compacts with mean particle size of 2 μm were prepared. The effects of adding TiO 2 and P 2 O 5 on the sintering behavior of glass powder compacts and on the properties of resultant glassceramics were studied. Mechanical, thermal, chemical and dielectric properties of sintered GCs were investigated with the aim to evaluate the potential of the GCs as substrate materials for microelectronics applications.

The effect of functional ions (Y3+, F−, Ti4+) on the structure, sintering and crystallization of diopside-calcium pyrophosphate bioglasses

“…1. In other words, TiO 2 acts as a nucleating agent, a fact often referred to in literature reports [51]. These variations in thermal parameters ( Table 2) and their implications on the sintering/crystallization behaviour are consistent with a decreased diffusivity, due to the larger ionic radius of Ti +4 in octahedral coordination (0.61 Å) [52].…”

Glass-Ceramic Coating on Silver Electrode Surface via 3D Printing

“…Diopside phase glass-ceramic has an interwoven structure, which has excellent dielectric and thermal properties, magnificent wear and corrosion resistance, and outstanding mechanical properties [26]. Due to the facile manufacturing process and low cost of the raw materials [27], the CMS system has been widely used in many areas, such as sealing materials for solid oxide fuel cells [28,29] and bioactive materials [30].…”

Influence of Ta2O5doping on mechanical and biological properties of silicate glass-ceramics

“…Due to the presence of both crystalline and residual glassy phase, glass-ceramics possess a combination of valuable properties of both glasses and ceramics [1]. Glass-ceramics have gain importance in recent years due to their remarkable dielectric, structural, mechanical [2] and biocompatible properties [3] which find application in various fields of telecommunication [4], architecture [5], and health care [6]. The physical and chemical properties of glass-ceramics mainly depend on the composition of glass, type and amount of the crystalline phase, microstructure, the heat treatment procedure and nucleating agents [7].…”
