SYNTHETIC FRAIPONTITE AND PROCESS FOR PREPARATION THEREOF |
摘要 |
<p>: An oxide or hydroxide mixture or coprecipitate having a three-component oxide composition comprising 5 to 45 mole% of SiO2, 35 to 65 mole% of ZnO and 0 to 60 mole% of A?2O3 is heated in the presence of water to form a crystal of the fraipontite type. The obtained synthetic mineral has a fraipontite type crystal structure and has a high whiteness and a large specific surface area. For example, this synthetic mineral is valuable as a color developer for a leuco dye.</p> |
