Abstract:In this work, some properties, such as sinterability, modulus of elasticity (E), coefficient of thermal expansion (CTE) and dielectric constant (ε r ), of composites constituted by nanoparticulate alumina (27-43 nm, 35 m 2 .g -1 ) in different contents (0 to 77 vol%) and a LZSA glass-ceramic composition (17.7Li 2 O-5.2ZrO 2 -68.1SiO 2 -9.0Al 2 O 3 , molar basis) were evaluated. Dry powders of the raw materials (alumina and LZSA parent glass, frit) were uniaxially pressed (40 MPa) and the obtained compacts were… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
