摘要 |
<p>There is disclosed chemically modified chrysotile asbestos fibers, more particularly phosphated asbestos fibers containing from 0.5 to 5% by weight of phosphate groups and heat treated phosphated asbestos fibers, both of which have an infrared spectrum which exhibits substantially no absorption within the range of 954-1080 cm-1. The novel phosphated asbestos fibers are characterized by reduced haemolytic and cytotoxic activities.</p> |
