Process Investigation for Purifying Hydrated Silica from Fly Ash by Acid and Alkali Combination Method Feng Lia , Xiangdong Liu, Yuanhe Guo School of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot 010051, China a Lifeng2010@163.com Keywords: Ash fly; Activation; Hydrated silica; Impurity Abstract.
In modern new methods, non-metallic minerals and their derived are used as raw materials as silica source for hydrated silica by precipitation method.
Their raw materials are mainly wollastonite, olivine, snake-tripe stone, kaolin, coal gangue, fly ash and so on[7-10].
In order to reduce the pollution to the environment, the ash fly thereby can be used as cheap and reliable raw materials for hydrated silica.

Introduction Water content of materials is an important technique parameter in many industry fields, and the moisture measurement of materials is a critical means to control the quantity of product process [1- 3].
Theories According to the characteristic of dielectric loss of materials, the absorbed microwave power of materials can be shown as follow
The microwave which is produced by the microwave source can be transmitted through the isolator and the adjustable attenuator, when it reaches the materials box, it will be absorbed by materials and the energy of the microwave will be decreased.
