Market Overview

Global neutron absorber material market size is projected to grow from USD 183.62 million in 2023 to USD 251.48 million by 2029, registering a CAGR of 5.38% during the forecast period. Neutron absorber materials are essential in the nuclear industry, where they play a crucial role in applications such as nuclear reactor control, radiation shielding, and nuclear waste management. These materials work by absorbing neutrons without causing a nuclear chain reaction, making them indispensable for safety and efficiency in nuclear technologies.

Key Neutron Absorber Materials

• Boron
  Primarily used as boron-10, boron offers a high neutron absorption cross-section. It is widely used in control rods for nuclear reactors due to its strong absorptive capability and cost-effectiveness.
• Cadmium
  Cadmium is another highly efficient neutron absorber, frequently utilized in control rods. It helps maintain criticality control in nuclear reactors by absorbing thermal neutrons effectively.
• Hafnium
  Known for its excellent corrosion resistance and mechanical properties, hafnium is a premium material used in nuclear reactor control rods. Its neutron-absorbing ability is robust, making it a reliable material for reactor design.
• Silver
  Silver is primarily applied in alloy form, particularly silver-indium-cadmium (Ag-In-Cd) alloys. These alloys are commonly used in control rods for their synergistic neutron absorption properties.
• Dysprosium
  A rare-earth element, dysprosium offers strong neutron absorption and is used in control rods and shielding applications in high-temperature environments.
• Samarium
