Compositional study and properties characterisation of alkaline earth feldspar glasses and glass-ceramics

Refractory glass–ceramics based on alkaline earth aluminosilicates

“…20 Small amounts (≤1 wt.%) of MoO 3 , V 2 O 5 and the noble metals rhodium and iridium were added as nucleating agents. No actual strontium or barium feldspars were reported, however.…”

The oxidative transformation of solid, barium-metal-bearing precursors into monolithic celsian with a retention of shape, dimensions, and relative density

“…As has often been observed with other precursors to celsian, 3,4,19,28,[39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][59][60][61]108 the final step of the reaction sequence within both of these specimens was the .

“…[23][24][25][26] Modest and thermally stable values of dielectric permittivity and loss at high frequencies also make monoclinic celsian attractive for use in radomes and other electromagnetic devices. While a glass-ceramic process can be used to produce a shaped celsian body, [40][41][42][43][44] temperatures in excess of 1760 ± C are required to melt a stoichiometric celsian composition. [17][18][19]24,[26][27][28][33][34][35][36][37][38] A shaped celsian green body can be produced by blending celsian powder with a malleable organic binder and then deforming the mixture into a desired shape by extrusion, forging, or pressing.…”

Fabrication and mechanical properties of carbon short fiber reinforced barium aluminosilicate glass–ceramic matrix composites

“…Advanced glass-ceramics, such as barium aluminosilicate (BaSi 2 Al 2 O 8 or BAS) typically exhibit high melting points, low coefficient of thermal expansion, and good oxidation resistance and dielectric properties [1]. For these reasons, they have potential as matrix materials for ceramic matrix composites with applications in electronic packaging, structural components and nuclear shielding [2][3][4][5][6].…”
