ABSTRACT:
A method of inhibiting corrosion in ammonia-water absorption machines that includes adding to an ammonia-water solution soluble silicon compounds. Examples of these silicon compounds include sodium silicate (Na.sub.2 SiO.sub.3), potassium silicate (K.sub.2 SiO.sub.3), lithium silicate (Li.sub.2 SiO.sub.3), silicic acid (H.sub.2 SiO.sub.5), and tetramethoxysilane (CH.sub.3 O).sub.4 Si. Sodium silicate is revealed as the preferred embodiment.
