Chemical & Material Interaction Analysis
Nickel Nitrate is classified as an inorganic salt / brine / ionic solution (electrolytic corrosion risk in metals, especially chlorides/halides, while thermoplastics remain largely inert). Used in water treatment, chemical dosing, brine handling, and industrial process streams. When selecting wetted components for Viton, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Exhibits no chemical degradation or structural loss at ambient room temperatures (72°F / 22°C), though elevated temperatures may accelerate minor permeation.
- Material Profile (Viton): Exceptional resistance to aliphatic and aromatic hydrocarbons, petroleum oils, concentrated mineral acids, and halogenated solvents at elevated temperatures. However, severely attacked by polar oxygenated solvents (acetone, MEK, ethyl acetate, THF), anhydrous ammonia, primary amines, and hot concentrated caustic soda via dehydrofluorination.
- Application Scope: Common wetted components include O-ring static/dynamic seals, pump diaphragms, valve seats, flange gaskets, and chemical transfer hose liners.

Frequently Asked Questions (FAQ)
Is Viton compatible with Nickel Nitrate?
Viton is rated A2-Excellent (Safe for Continuous Ambient Service) with Nickel Nitrate (Formula: Ni(NO3)2, CAS: 13138-45-9). Exhibits no chemical degradation or structural loss at ambient room temperatures (72°F / 22°C), though elevated temperatures may accelerate minor permeation. Recommended for ambient storage tanks, transfer lines, and seals. If process temperatures exceed 100°F (38°C), verify pressure de-rating factors.
What is the best alternative material for handling Nickel Nitrate?
If Viton does not meet your temperature or pressure requirements for Nickel Nitrate, the highest-rated Grade A alternatives are Polypropylene, PTFE, EPDM, PVC. Always verify O-ring elastomers and metallic fasteners separately before full-scale deployment.
