Formation of alpha/beta-Si(3)N(4 )nanoparticles by carbothermal reduction and nitridation of geopolymers
Bağcı, Cengiz; Yang, Qun; Kriven, Waltraud M. (Wiley, 2019)Silicon nitride (Si3N4) particles with various alpha/beta-Si(3)N(4 )ratios were fabricated from geopolymer (GP)-carbon compositions (M2O center dot Al2O3 center dot 4.5SiO(2)center dot 12H(2)O+18C), where M is an alkali ... -
Fully reacted high strength geopolymer made with diatomite as a fumed silica alternative
Bağcı, Cengiz; Kutyla, Gregory P.; Kriven, Waltraud M. (Elsevier Ltd, 2017)Geopolymers are formed by mixing of aluminosilicate sources with alkaline meta-silicate solution at room temperature. In the current study, diatomite of Turkish origin was fully utilized as a fumed silica alternative for ... -
In situ carbothermal reduction/nitridation carbon-nano powder added geopolymer composites
Bağcı, Cengiz; Kutyla, Gregory P.; Kriven, Waltraud M. (American Ceramic Society, 2014)Geopolymer was prepared by mixing metakaolin (Al2O3 center dot SiO2) with sodium water glass solution and then the activated carbon nano powder was added the geopolymer. To determine the best composition for carbothermal ... -
Synthesis and characterization of silicon carbide powders converted from metakaolin-based geopolymer
Bağcı, Cengiz; Kutyla, Gregory P.; Seymour, Kevin C.; Kriven, Waltraud M. (Blackwell Publishing Inc., 2016)Silicon carbide (SiC) ceramic powders were synthesized by carbothermal reduction in specific geopolymers containing carbon nanopowders. Geopolymers containing carbon and having a composition M2O·Al2O3·4.5SiO2·12H2O+18C, ...
