Quenching experiments were used to investigate the solid solution range, thermal stability, and selected phase relationships of silico-ferrite of calcium and aluminum (SFCA) within the Fe2O3-CaO-Al2O3-SiO2 (FCAS) system. SFCA was found to be stable w

Although dicalcium silicates can constitute up to 10 vol% of many modern hematite/goethite iron ore sinters, traditional mineralogical investigations of such sinters have largely overlooked this phase and focused on the more abundant iron oxides and

The time dependence of the deuterium permeation rate through impurity‐doped copper membranes was measured in the temperature range 300–700 °C. Copper membranes that were doped with Er, Zr, and Ti all exhibited permeabilities that were nearly equ

In the Micronesian island of Ponape blood pressures were found in 1947 and again in 1953 to be very low and to show no difference between age groups. As part of the US Trust Territory of the Pacific from 1945, the island had begun to change in the di
