Abstract: Surface tension is important power for liquid in space microgra-vity.Indium and Cadmium was sealed in quartz glass tube,heated and thencooled slowly.We have studied Indium-Cadmium quartz glass wetting propertyand other surface phenomenon.Indium can wet quartz glass and Indium candislove Cadmium in the earth,but Indium can not wet quartz glass and In-dium-cadmium turn into two spheres in space microgravity.We measured theradii and sphericity of Indium sphere.
