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 provides 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 a-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 reviewed and predicted.
