The results of XRD and chemical analysis showed that products contain crystal water. When the temperature exceeds 300 ¡æ, dehydration began, which led to dehydration accompanied with producing and the shape of the product is not ideal. [ Last edited by jw227 on 2009-9-21 at 16:50 ] |

The XRD and chemical analysis shows that there is water of crystalization on the produchtion. when under the reaction tempreture, which is over 300@, the production begains to dehydrate and decompose. this dehydration while formation makes an irregular crystal form of the product 3q |
