Lead-Bismuth Eutectic
Lead-Bismuth Eutectic (LBE) is a mixture of lead and bismuth that has a specific composition, typically around 44.5% lead and 55.5% bismuth by weight. This alloy has a low melting point of approximately 125 °C (257 °F), making it useful in various applications, particularly in nuclear technology as a coolant in fast neutron reactors.
LBE is notable for its excellent thermal conductivity and resistance to corrosion, which enhances its performance in high-temperature environments. Additionally, it has a low vapor pressure, reducing the risk of gas release during operation. These properties make LBE an attractive option for advanced nuclear systems and other industrial processes.
