“…Voorhees et al [30] reported for 6% PEG/alumina composite, a rapid WL beginning at 238 C which marked the initiation of the thermal degradation of the PEG. PEG decomposes, yielding a series of 27 products, via disproportionation, hydrogen abstraction, and rearrangement with only minor oxidation [30]. Once the primary products distill from the melt, they are subjected to oxidation reactions at the surface of the alumina and in the gas phase.…”

Preparation, characterization, and electrical properties of ZSM-5/PEG composite particles

ZSM‐5/PEG composites were synthesized by a simple solution method with polyethylene glycol (PEG) and H‐ZSM‐5 zeolite (Si/Al = 11.4). The obtained composites were characterized using X‐ray powder diffraction and Fourier transform infrared spectroscopy. The obtained results indicated that the ZSM‐5 was physically combined with PEG. The thermal properties and thermal stability were investigated by thermogravimetric and differential thermal analyses. In situ electrical conductivity was used to follow‐up the changes in the electrical conductance during the heating of the ZSM‐5/PEG composite. It was found that ZSM‐5 is able to effectively enhance the electrical conductivity of PEG. The results showed that the obtained weight loss during the composite decomposition to charcoal is accompanied by a decrease in the electrical conductivity. Moreover, the removal of the formed charcoal is associated with an electrical conductivity increase. Calcining the ZSM‐5/PEG composite having a content of 30% results in many effects on the structural, textural, and electrical properties of the obtained products. POLYM.

“…This observation confirms that the high temperature annealing causes loss of a significant amount of carbonaceous materials, from PEG-6000, in line with its decomposition profile which is generally held to involve the loss of short oligomers. 24,25 Much of the fluoride is also lost as the conversion from NH4TiOF3 MCs to TiO2 MCs proceeds, although some fluoride remains even after extended heating. This XPS data, in conjunction with the structural data (vide infra), indicates that the optimal duration of annealing at 450 o C is around 4 hours.…”

“…Organic additives are widely used in ceramic slurry preparation (as in tape casting and gelcasting [1][2][3][4][5][6][7][8], green compact fabrication (as in powder metallurgy [9][10][11][12][13][14][15][16][17][18][19] ), thick-film materials development, [20][21][22][23][24] and other applications. [25][26][27][28][29] The ingredients are typically functional phases in the form of solids, and organic additives in the form of liquids, solutions, or suspensions.…”

Burnout of the organic vehicle in an electrically conductive thick-film paste

The burnout of the organic vehicle in a silver-particle, glass-free, electrically conductive, thick-film paste during firing in air was studied. For a vehicle consisting of ethyl cellulose dissolved in ether, burnout primarily involves the thermal decomposition of ethyl cellulose. The presence of ether with dissolved ethyl cellulose facilitates the burnout of ethyl cellulose. Excessive ethyl cellulose hinders the burnout. A high heating rate results in more residue after burnout. By interrupting the heating at 160°C for 15 min, the residue after subsequent burnout is diminished probably because of reduced temporal overlap of the processes of organic burnout and silver particle necking. By interrupting the heating at either 300°C or 385°C for 30 min, the temperature required for complete burnout is reduced. The addition of silver particles facilitates drying at room temperature and burnout upon heating.
