SOLIDIFICATION METHOD OF SILICA POWDER AND HIGH-PURITY SILICA SOLIDIFIED BODY |
| 摘要 |
<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-purity silica solidified body having practical strengths without recourse to firing at a high temperature.SOLUTION: The provided method for manufacturing a silica solidified body includes a grinding step of obtaining an activated silica powder having a mechanochemically activated surface by grinding a silica powder in a dry state and a base treatment step of treating the activated silica powder with a basic solution including virtually no metal elements so as to obtain a silica solidified body by dissolving and re-depositing the surface of the activated silica powder.</p> |
