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 ... -
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, ...
