Curing reaction of epoxy resins with diamines
Abstract The curing reaction of a commercial bisphenol A diglycidyl ether (BADGE) with ethylenediamine (EDA) was studied by differential scanning calorimetry. Different kinetic expressions were found with isothermal (low temperature range) and dynamic (high temperature range) runs. Two competitive mechanisms are shown…
Improvements in Mechanical Properties in SiC by the Addition of TiC Particles
Silicon carbide ceramics containing up to 24.6 vol% dispersed TiC particles yielded fully dense composites by hot‐pressing at 2000°C with 1 wt% Al and 1 wt% C added. The micro‐structure consists of fine TiC particles in a fine‐grained SiC matrix. Addition of TiC particles increases the critical fracture toughness of S…
Penalty Function Improvement of Waveguide Solution by Finite Elements
The finite element method is a well-established method for the solution of a wide range of guided wave problems. One drawback associated with the powerful vector formulation is the appearance of spurious or nonphysical solutions. A penalty function method has been introduced to the finite element formulation, to reduc…

Mineralogy, chemistry, and physical properties interrelationships of some sensitive clays from Eastern Canada
This paper describes the use of quantitative mineralogy and specific surface area in interpreting the index properties of clayey soils from nine sites in Eastern Canada. Samples representative of the Tyrrell, Laflamme, Champlain, and Goldthwait marine seas and Lac Barlow–Ojibway have been studied.Quantitative X-ray di…
Crystal optical studies of spontaneous and precursor polarization inKNbO3
High-resolution measurements of the cubic refractive index $n$ ($700 \mathrm{K}<T<1000 \mathrm{K}$) and of the tetragonal and orthorhombic birefringence $\ensuremath{\Delta}n$ ($480 \mathrm{K}<T<705 \mathrm{K}$ and $300 \mathrm{K}<T<490 \mathrm{K}$, respectively) are performed on ${\mathrm{KNbO}}_{3}…
Crystal structure and cation distribution in titanomagnetites (Fe (sub 3-x) Ti x O 4 )
A systematic study of the crystal structure of titanomagnetites was undertaken to characterize the effects of composition and quenching temperature on the cation distribution. Powder specimens ranging in composition from pure magnetite to a slightly nonstoichiometric ulvrispinel were synthesized at temperatures betwee…

A Raman spectroscopic study of glasses in the system CaO-MgO-SiO 2
The Raman spectra of a number of glasses in the system CaO-MgO-SiO2 have been prepared using solar furnace techniques. The spectra of glasses along the SiO2-CaO &apos; SiO2-MgO and SiOz-Cao sMgo sO joins are similar to those obtained in other studies, and are interpreted in terms of vibrations of tetrahedral silic…
Intercalation Method using Formamide for Differentiating Halloysite from Kaolinite
Abstract A rapid and simple test to distinguish halloysite from kaolinite in mineral mixtures has been developed based on differences in the rate and extent of formamide intercalation. With halloysite, complex formation was both rapid (<1 hr) and complete, whereas no significant intercalation occurred with kaolinit…
