Zusammenfassung:	Liquid tin (Sn) is a promising coolant for liquid surface divertor of fusion reactors. However, material compatibility of liquid Sn with structural materials is one of the important issues. The purpose of the present study is to investigate the corrosion resistance of tungsten (W) materials such as pure W, W-5Re alloy and W based sintered alloy (HAC2) in liquid Sn. Static corrosion tests were performed at 773 K for 250 hours. Pure W and W-5Re revealed corrosion resistance in liquid Sn, though HAC2 corroded due to dissolution of sintering additives.
