    摘要: A process is described for preparing peroxyborate agglomerates having an active oxygen content of at least 14% by weight in which amorphous primary particles composed of peroxyborate prepared by a spray drying process are subjected to compacting pressing-agglomeration. Briquettes, compressed strips and tablets can be obtained which can be comminuted, if desired, to peroxyborate granules of desired particle size and bulk density. Advantageous, optionally colored, peroxyborate agglomerates, particularly peroxyborate granules are prepared. Preferred agglomerates and granules are composed of sodium peroxyborates.
