Preparation and properties of the barium borate glassy matrix composite materials containing fused silica and monoclinic zirconia

Improved Thermal Stability and Wettability Behavior of Thermoplastic Polyurethane / Barium Metaborate Composites

“…19 The characteristic XRD peak of barium metaborate 2θ=23º-24º. 20 XRD patterns of all the composite samples showed sharp peaks that barium metaborate particles were dispersed homogenously and they were buried inside the polymer matrix.…”

Silica–calcium zirconate nanocomposite, studying its thermal and electrical properties

“…It should be noted that, the coefficient of thermal expansion was decreased with enhancing CaZrO 3 /silica ratio. Thus, the relationship between the nanocomposite components and coefficient of thermal expansion is calculated as follows: 26,29 …”

“…For example, low dielectric constant of silica reduces the thickness of parasitic capacitance, resulting in fast switching and less heat loss. [23][24][25][26] Silica and CaZrO 3 have nearly similar physical properties such as low thermal expansion coefficient and good thermal shock resistance. Therefore, studies on the preparation of composites with improved mentioned properties are considered.…”

Phase formation and properties of the BaO–B2O3–SiO2 and –Al2O3 ceramics prepared via an aqueous suspension route

“…Furthermore, it is also characterized [2] by the excellent dielectric properties and the equal coefficient of thermal expansion (CTE) to achieve the thermal match between the substrates and the metallized wiring layer or silicon. In most of methods to develop such LTCC materials, the common method is to fabricate glass ceramics or ceramic/glass composites by using low-melting glasses as a flux agent and functional ceramic particles as filler, respectively [3]. Because the liquid phase sintering can supply various facilities for the achievement of the densification sintering and the design of physical properties [1,3], the glass materials play a very important role in the fabrication of LTCC materials.…”

Nevertheless, the manufacture of most of the glass materials is usually a complex process including high-temperature melting and cooling.…”
