In semiconductor fabrication it is common practice to use a grain‐growth promoter with pure germanium or silicon with very small quantities (parts per million) of a promoting agent (such as boron or phosphorus) to obtain the desired semiconducting properties. Several materials such as antimony, boron, lead, lithium, potassium, and sodium were investigated as possible agents for the promotion of grain growth in cadmium manganese ferrites. It was noted that the characteristics of ferrites could be affected by treating with these agents before sintering. The boron additions to these ferrites accelerated the reaction rates (catalytic action) and affected the characteristics during sintering. The methods of preparation and the observed results are discussed.
