Preparation of essentially alkali-free borosilicate crystals having a zeolite structure |
| abstract |
Essentially alkali-free borosilicate crystals having a zeolite structure and a size of from 2 to 150 mu m, measured over the longitudinal crystallite axis, are prepared by a process in which an SiO2-containing mixture of water, a tetraalkylammonium compound, a boron component and ammonia is reacted hydrothermally in the absence of a metal hydroxide or of a metal salt in a molar ratio of ammonia/tetraalkylammonium of from 3:1 to 150:1. |
