摘要:

AbstractHeats of solution of a series of glasses in the system PbO‐B2O3were measured in 2Nnitric acid with a simple vacuum‐bottle calorimeter. Heats of solution of a series of glasses in the system PbO‐SiO2ranging in composition from 6 to 35% of SiO2were measured in a mixture of HF and 2.5Nnitric acid with an electrically calibrated isothermal jacket calorimeter. From these data and heats of fusion available in the literature, calculations were made of the heats of reaction of the component oxides in either amorphous or crystalline states in forming glasses in these sy

摘要:

AbstractRefractory samples removed from the lining of a blast furnace exhibiting normal behavior were analyzed for chemical and mineralogical changes. The changes observed in the lining of this furnace are discussed and their probable effect upon the refractory life is indicated; On the basis of the findings, suggestions are made regarding blastfurnace refractory practice.

摘要:

AbstractIn spite of the large amount of work which has been done in the field of plasticity, none of the explanations are entirely fitted to the facts when dealing with clay‐water systems of pasty consistency. As there is now a considerable amount of data on carefully fractionated and cleaned kaolinite, it has been possible to substantiate a new mechanism of plasticity which is termed the “stretched‐membrane theory.” This theory accounts for the plasticity of the clay masses by the compression of the whole due to the surface envelope of water which tends to push the particles together by capillary forces. This theory is shown to be reasonable by both direct and indirect proof; however, it in no way changes the general picture of the forces acting between the particles in a suspension as portrayed by the colloid chem
