Abstract:
Various processing routes were investigated for the synthesis of sodium polysialate polymers. Work was done to optimize density, reactivity, and mechanical properties through processing. Also known as geopolymers, sodium polysialate inorganic polymers are made by condensing metakaolinite in highly alkaline water glass to yield a three dimensional Al-O-Si structure. Scanning and transmission electron microscopy (SEM, TEM and EDS) along with mercury intrusion porosimetry (MIP) analyses were used to determine sample density, nature of the pore structure, and degree of reactivity. Vickers hardness, compressive strength, and flexural strength values were measured using standard testing procedures. Optimum density and reactivity was attained used a high pressure, autoclave apparatus operated at 80 degrees C for 12 hours. Finally, metal powder was added as a filler phase in order to toughen the intrinsic material.
