Preparation method of ceramic hollow ball :Volcanic ejecta of Mt.Unzen-Fugen was mixed with Kibushi clay of 20 vol% as a binder with pot mill. The mixture was pressed into a half ball with plaster mold. Two of the ball were consolidated into a hollow ball and heated at 1200ﾟC for 1 h. Using this method, we can obtained ceramic hollow ball.Formation method of pores in the shell wall of the ceramic hollow ball :Cellulose up to 15 mass% or chopped carbon fiber up to 1 mass% were mixed to the mixture as a pore former. Ceramic hollow ball was prepared with the above-mentioned method. There were many open pores in the shell wall of the ceramic hollow ball.Taking in and taking out ability of water :Using vacuum infiltration, we could take water in the hollow part of the ball. We also could take out water from the hollow part by exposing the ball stored water in hot air.

陶瓷空心球的制备方法：用罐式粉碎机将云仙风原山的火山喷出物与20体积%的木伏粘土作为粘合剂混合。用石膏模具将混合物压成半球。将两个球固结成空心球，并在1200 ℃下加热1小时。陶瓷空心球的壳壁中的孔的形成方法：将最多15质量%的纤维素或最多1质量%的短切碳纤维混合到混合物中作为造孔剂。采用上述方法制备了陶瓷空心球。陶瓷空心球的壳壁有许多开孔。吸、出水能力：采用真空渗透法，可以在空心球的中空部分进行吸、出水。我们也可以通过将储存水的球暴露在热空气中来从中空部分取出水。
