Abstract
Official abstract text for this publication.
Sodium-tin and sodium-tin-lead compositions have been identified and created that exhibit better reactivity characteristics (i.e., are less reactive) than sodium metal under the same conditions, making these compositions safer alternatives to sodium metal for use as a coolant. These compositions include compositions having at least 90% sodium (Na), from 0-10% lead (Pb) and the balance being tin (Sn).
First claim
Opening claim text (preview).
What is claimed is: 1. A composition consisting of: 94.5-95.5 mol % Na; 2.5-3.5 mol % Pb; and the balance being Sn. 2. The composition of claim 1 , wherein the composition is: 95 mol % Na; 3 mol % Pb; and the balance being Sn. 3. The composition of claim 1 wherein the composition supports a continuous reaction with air at a temperature higher than that which pure sodium supports a continuous reaction with air. 4. The composition of claim 1 wherein the composition supports a continuous reaction with air at a temperature at least about 100% higher than that which pure sodium supports a continuous reaction with air.
