MEANS FOR REDUCING THE RELATIVE DENSITY AND PROCESS FOR THEIR PRODUCTION |
| 摘要 |
Means for reducing the relative density of solid materials consisting of roughly spherical, synthetic, 30-120 mu m, wide, compacted, acicularly-interlinked calcium silicates, the external surface of which is subsequently closed. The means can be produced by applying a plastic layer to their surface. |
