摘要
The paper presents a new method to synthesize β-Sialon bonded corundum brick (β-SBCB) from Al-Si alloy directly and easily under 1430℃ , the volume expansion of reaction between Al powder and Nitrogen can help to establish the fast diffusion channel in Al-Si alloy; the suitable crystal seed of Si3N4 is helpful to the fast synthesis of β-Sialon.
