MoC, melting point 2,692 degrees C, sp gr, 8.5; Mo<sub>2</sub>C , melting point 2,687 degrees C, sp gr, 8.9.
Industry:Mining
Modification of the Helmholtz concept of the electrical double layer which surrounds a particle immersed in an electrolyte. In Gouy's view there is only one diffuse layer. The ionic atmosphere near the surface of the particle is highly charged, but this ionization diminishes gradually outward into the ambient liquid.
Industry:Mining
Modification of the open-hearth process of steel manufacture with pig iron and iron ore as the charge.

Modification of the open-hearth process of steel manufacture with pig iron and steel as the charge.
Industry:Mining
Modification of the pan-amalgamation process; ore slurry flows continuously through a series of pans and settling tanks.

Mohr's theory of failure utilizes the well-known stress circle and the envelope of a family of circles as criteria for failure of materials subject to biaxial or triaxial stress. Thus Mohr's theory predicts that failure of materials is due to failure in shear, whereas Griffith's theory postulates that it is due to failure at crack tips.
