β‐Ca 2 Si0 4 can be obtained from a mixture ofCaC 2 O 4 ‐H 2 O and amorphous silica by firing at 950°C as opposed to a normal sintering temperature around 1450°C. If CaCO 3 is used instead of CaC 2 O 4 ·H 2 O, four repeated firings under CO 2 atmosphere are needed to obtain β‐Ca 2 SiO 4 . The role of CO 2 atmosphere d…
Abstract Die physikalische Alterung von amorphen Polymeren wird ausgehend von experimentellen Ergebnissen auf phänomenologischem Niveau diskutiert, wobei die physikalische Alterung als selbständiger Relaxationsprozeß verstanden wird. Unter Benutzung einer allgemeinen Scalinghypothese wird ein konsistentes Bild für die…
Bimetal joints between high-speed steel and medium-carbon steel are often required in the tool industry. Friction welds were made between this dissimilar combination of materials and the joint behaviour was evaluated under conditions appropriate to the intended service applications. The welding was carried out under o…
Diffusion couples are used to study the reaction between CaO powder and Fe 2 O 3 All heat treatments were performed in air. The growth and morphology of calcium ferrites is studied at different temperatures. It is shown that CaO·2Fe 2 O 3 , starts to form at about 1125°C, while the accepted phase diagram for equilibri…
This-paper describes a procedure for HV insulating system design which combines the classical approach of changing the distances between system elements with optimization of their contours. An integral equation technique for solving electric fields, which is improved by cubic spline expansion for surface charge densit…

Algal taxa (281) were identified from 31 ombrotrophic bogs and 3 weakly minerotrophic fens from Manitoba to Newfoundland. Species richness increases from continental to maritime and coastal bogs, mainly as a result of an increase in Chlorophyta, especially Desmidiaceae. Species richness is related to (i) availability…

We have calculated two linear polarization effects in the elastic scattering of x rays and \ensuremath{\gamma} rays (in the energy range a few keV to little above 1 MeV) from targets with Z ranging from 13 to 92, using Rayleigh scattering amplitudes obtained numerically with the procedures of Kissel et al. We consider…

A review ofthe corrosion ofalloys in oxidizing/sulphidizing environments is presented,with specialemphasis on high temperature alloys. As in part I* of this work which dealt with corrosion in pure metals, the simultaneous formation ofoxide and sulphide is considered in detail by describing possible reaction paths and…
A reflective multicolor matrix LCD with micro color filters is investigated. In order to improve the brightness of the LCD, contrast and brightness of various liquid-crystal display modes are analyzed. This analysis suggests the choice of the phase-change-type guest-host mode. The optimal parameters for this mode are…

The paper describes a method for measuring the pressure dependence of the thermal conductivity and the heat capacity of hard materials and single crystals. Two parallel metal strips are evaporated onto a flat surface of the specimen, one being used as a heater, the other as a resistance thermometer. The appropriate th…

Abstract The influence of cryo‐ground rubber (CGR) on melt flow and mechanical properties of polypropylene has been investigated. Cryo‐ground rubber was incorporated in the polypropylene matrix (a) in powder form and (b) as masterbatch with natural rubber. Natural rubber was found essential as a dispersing agent. The…
This paper reviews the electronic transport properties of compositionally graded materials. Band gap grading is a powerful tool for engineering the energy band diagram of a device and thus modifying its electrical transport properties (band gap engineering) (1). The most interesting property, which has far reaching co…
