Development of Sialon Ecomaterials Drived from Solid Waste of Containing Silican and Aluminum

The synthesis of Sialon ecomaterials drived from solid waste of containing silican and aluminum pro-vides a new method to utilize the solid waste high-technically,and a new green process for low-cost preparation of Sialon material.Blast furnace slag,coal gangue,fly ashes,sediment,tailings,etc,are briefly introduced.It could be designed to synthesize α-Sialon,β-Sialon,O′-Sialon,etc,composite materials based on the chemical composition of these solid waste.The present development and prospects of Sialon ecomaterials drived from solid waste are re-viewed and predicted.
