ABSTRACTTGA and FTIR were employed to investigate the effects of dibutyl phthalate and butyl benzyl phthalate on the thermal degradation behavior of PVB, a binder used commonly for tape casting. Butyl benzyl phthalate was found to enhance the crosslinking of the PVB binder when heated in a nitrogen atmosphere during binder pyrolysis, which retarded its thermal degradation.The interaction between AIN powder and PVB binder was also studied by using TGA, XPS and a special furnace for collecting residual carbon. Intrinsic char and gas phase mediated char were studied separately.

Liquid crystalline epoxy, 4,4’-Diglycidyloxy-α-methylstilbene (DOMS) was synthesized and Aluminum Nitride reinforced DOMS composites were fabricated by melt blending with sulfanilamide (SAA) as a curing agent. Thermal degradation behavior was investigated by thermogravimetric analysis (TGA) under nitrogen atmosphere at the temperature range from 30 to 1000°C. Activation energies for decomposition (Ed) by TGA were determined as a function of conversion by weight loss process.

Liquid crystalline thermosetting epoxy, 4,4’-Diglycidyloxy-α-methylstilbene (DOMS) was synthesized and characterized with cross-polarized optical microscopy (POM) and differential scanning calorimetry (DSC). Alumina reinforced DOMS composites were fabricated by melt blending with sulfanilamide (SAA) as a curing agent. To investigate thermal degradation behavior, thermogravimetric analysis (TGA) was performed under nitrogen atmosphere at the temperature range from 30 to 1000°C. Activation energies for decomposition (Ed) by TGA were determined as a function of conversion by weight loss process.

Abstract Various siliceous agriculture waste (SAW) such as rice husk, wheat husk and bagasse have been investigated to study their thermal degradation behavior using Thermogravimetric Analyzer (TGA) technique. The focus of this research is to conduct TGA of raw and acid treated (20% HCl & 1M H2SO4) SAW at heating rate 10°C/min in the atmosphere of nitrogen. The results were analyzed on the basis of thermograms and it was inferred that 24 hours soaking with 20% HCl prior to thermal degradation enhanced the percent weight loss. The process also improved the percentage of residual weight of SAW indicating the extraction of amorphous silica with increased purity. The effect of acid treatment was verified by determining chemical composition of SAW samples before and after soaking with 20% HCl. Proximate analysis, thermal degradation temperature ranges and percentage of residual weight at 800°C for each of rice husk, wheat husk and bagasse were also quantified to observe the thermal degradation behavior. XRF analysis was performed to observe the effect of acid treatment for extraction of pure silica.
