An Accelerating Rate Calorimeter (ARC) can be used to evaluate the thermal stability of hazardous materials by simulating adiabatic conditions to determine self-heat rate and pressure data. It can identify the onset temperature of an exothermic or endothermic event, model reaction kinetics, and provide data for safety applications like vent sizing. This makes ARC crucial for safety and performance evaluations of materials, explosives, propellants, and batteries.
Thermal stability evaluation:
Assesses the thermal behavior of materials, especially those that are self-reactive, and determines conditions under which they could become unstable.
Provides data used to model the kinetics of a reaction, which helps predict how a reaction will proceed over time and under different conditions.
Measures a system’s temperature and pressure response over time, which is vital for understanding how a system reacts when heated.
Used to test the safety of chemicals, explosives, propellants, and batteries to prevent thermal runaway and ensure safe storage conditions.
Can detect and measure reactions with very low heat generation rates, down to approximately 1 to 2 watts per kg.
Allows for testing under constant temperature conditions to evaluate long-term stability.
Can analyze reactions involving gas and solid phases.
