摘要： Pure Maddrell salt is produced by heating sodium phosphate to temperatures of 250.degree. to 420.degree. C. The sodium phospate used as starting material is sodium trimetaphosphate or a mixture of sodium trimetaphosphate with Maddrell salt, monosodium orthophosphate or disodium pyrophosphate, the mixture containing Na and P in a molar ratio of 1:1. Prior to heating the starting material, it is admixed with 0.5 to 5 weight% of orthophosphoric acid, polyphosphoric acid, phosphorus pentoxide or at least one salt of a volatile base forming polyphosphoric acid at the temperatures specified. The resulting mixture is calcined over the period necessary to transform the starting material to Maddrell salt.

摘要： Aluminum polyphosphate is made. To this end, solid aluminum hydroxide and polyphosphoric acid which are used in proportions corresponding to an Al:P molar ratio of 1:2.5 to 1:3.5, are introduced separately from, but concurrently with, one another into a reaction zone kept at 150.degree. to 200.degree. C. A moist friable consistency of the starting materials is maintained in the reaction zone by continuously mixing, kneading and comminuting them over substantially the entire period during which they are introduced into the reaction zone. The reaction is continued until a dry sandy powder is formed; and the powder is annealed at 400.degree. to 600.degree. C. over a period sufficient to yield a product undergoing a 0.5 to 1% weight loss on ignition.
摘要翻译：制成聚磷酸铝。为此，以与Al:P摩尔比为1:2.5〜1:3.5的比例使用的固体氢氧化铝和多磷酸分别从彼此分开引入到保持在150℃的反应区中通过在它们被引入反应区域的基本上整个时间段内连续地混合，捏合和粉碎它们，在反应区域中维持起始材料的潮湿脆性稠度。继续反应直至形成干燥的沙质粉末; 并将粉末在400℃至600℃下退火一段足以产生在点火时经历0.5至1重量％失重的产物。

摘要： Hardeners of condensed aluminum phosphates for use in water-glass cementing compositions and process for making them. The hardeners consist substantially of a short chain aluminum polyphosphate with a chain length of 3 to 6 and a long chain aluminum polyphosphate with a chain length or more than 40. Quick-setting hardeners contain a high proportion of the short chain component and slow-setting hardeners contain a high porportion of the long chain component.
