Asbestiform crystalline calcium sodium or lithium phosphate, preparation and compositions

摘要: Asbestiform crystalline calcium M phosphate, where is sodium or lithium, having a length to average diameter ratio of at least 5:1, can be prepared by forming melt source oxygen, calcium, phosphorus and mole about 15 percent 30 2 O, 48 60 P O 5 20 37 CaO, cooling the within range 500° C. 750° for sufficient time permit blocks phosphate form, fiberizing into asbestiform crystals. Such phosphates are useful prepare composites organic polymeric materials.
