摘要：

Long-chain crystalline ammonium polyphosphates and potassium ammonium polyphosphates were readily produced by thermal dehydration of orthophosphate or short-chain polyphosphates in a stream of gaseous ammonia. The products were high in total P but low in available phosphorus (citrate + water soluble);however, greenhouse tests showed that they are highly effective sources of nitrogen and phosphorus. © 1979, American Chemical Society.
