^ust how reactive do you want your Sodium to be? if you want it at its maximum energy level, in an easily-handled, easily-contf oiled form, your answer is High Surface Sodium (HSS) on Inert Solids! Using simple, easy-to-follow techniques, our researchers have applied atomic layers of Metallic Sodium to inert solids such as salt, soda ash, carbon, alumina and sand. HSS is free-flowing over a wide temperature range and has a large surface-to-weight ratio of Sodium. Reactions can be carried out in seconds instead of hours. The high surface area of Sodium in HSS, available for immediate reaction, is the key to its importance to industry. HSS provides, through the complete and rapid reaction of Sodium, the following advantages: 11 Easy control of reaction rates and temperatures above and below the melting point of Sodium 11 Simple adaptation to continuous operations 11 Dry-way reactions of Sodium H Greater safety by eliminating flammable solvents 11 High yields H Preparation of products' in finely divided and reactive states H Means of avoiding induction periods

NOTE: We do not produce HIGH SURFACE SODIUM. Our product is Metallic Sodium from 1 lb. bricks to tank car quantities. However, our technical staff can demonstrate the simplicity of preparing and utilizing HSS in your own plant in available equipment.
Particle size for Sodium Dispersions and HSS can be controlled within narrow ranges.
