Thermal stability of thaumasite
Materials and Structures, 2014The thermal stability of thaumasite, Ca3Si(OH)6(SO4)(CO3)·12H2O, has been determined and new thermodynamic data defining its stability and solubility are reported. The absolute upper limit of stability of thaumasite in a saturated aqueous solution at 1 bar pressure is 68 ± 5 °C.

Thermal stability of polypyrroles
Polymer International, 1992AbstractThe effect of dopants and level of doping on the thermal stability of polypyrrole at 90, 120 and 150°C in dry air and nitrogen was investigated by monitoring the decay of conductivity. Polymers doped with aromatic anions (p‐toluene sulphonate and p‐chlorobenzene sulphonate) exhibit better stability than polymers doped with an aliphatic anion ...

Thermal stability of polyaniline
Polymer Bulletin, 2000Among conducting polymers with metallic characteristics, polyaniline (PANI) is claimed to have one of the highest environmental stability. From an industrial point of view it would be useful to be able to thermally process this material into useful products using conventional techniques such as extrusion, stretching, rolling, etc., which generally are ...

Thermal stabilization of austenite [PDF]
Metal Science and Heat Treatment, 1972 1. To determine the thermal stabilization characteristic of austenite the complex magnetometric method that requires special apparatus can be replaced with measurements of the hardness. 2. There is a good correlation between the results obtained by measuring the hardness and the data obtained by magnetic analysis.

Silicalites and their thermal stability
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19851. The likelihood of obtaining silicalites 1 or 2, distinguished by the structural features of their framework, depends on the composition of the mixtures used in their preparation. The nature of the organic component has the greatest influence on the results of the crystallization.

The thermal stabilization of austenite
Acta Metallurgica, 1966Abstract It is proposed that the thermal stabilization of austenite occurs because of the pinning of martensite nucleus-austenite matrix interfaces by segregated carbon. The kinetics of thermal stabilization implicit in this model are quantitatively developed and compared with reported austenite stabilization behavior.

The thermal stability of AlN powders and thin films has been investigated using reflection high-energy electron diffraction (RHEED) and X-ray diffraction. AlN powder was treated thermally and chemically to assess the oxidation resistance of this compound and to identify the phases formed.

Thermal stability of lubricants
Chemistry and Technology of Fuels and Oils, 19651. In selecting or recommending a lubricant intended for prolonged use in a frictional assembly (with one-shot lubrication), one must take into account the thermal stability that is estimated on the basis of the decomposition or oxidation rate under the service conditions. 2.

Thermal stability of bropirimine
International Journal of Pharmaceutics, 1988Abstract A differential scanning calorimetric study of bropirimine reveals that the thermal stability is decreased upon admixture with polyethylene glycol and other excipients added to enhance solubility profiles. The degradation involves the substitution of the bromine atom in the molecule to generate 2-amino-6-phenylpyrimidin-4(3H)-one.

Similar to its mechanical and barrier properties, the homogeneous dispersion of silicate layers in a polymer matrix can also enhance the thermal degradation of PNCs. This chapter highlights the effects of different organically modified clays and their dispersion on polymer thermal stability.
