Abstract:
Method of making a burnable neutron absorber of boron carbide in a matrix of aluminum oxide. In the practice of this method, boron-carbide particles are coated with a pore former and then they are mixed in a slurry with aluminum oxide powder. When the slurry is subsequently dried and sintered, the pore former is burned out and a body is formed including the boron-carbide particles in a matrix of aluminum oxide with substantially all boron-carbide particles in the body surrounded by a void.
