Most of the sand that is used as a mould-making material is silica sand [10][12], while the binder used is clay [8]. Silica sand is a material that is easily available and cheap, besides that, silica sand can be used several times as a mould material. Although it is easy and cheap, silica sand can only be foundThe distribution of hydrate formation in the different-sized silica sand beds (100, 200, and 400 mesh) is presented in Fig. 12, while that of in 150-mesh and 300-mesh silica sand are displayed in the supplementary information).Effect of silica sand size and saturation on methane hydrate formation
