Silver clay

Abstract

The invention discloses a sliver clay, which is characterized in that the silver clay includes the following materials and the mass proportion: 85-92% of colloidal silver powder, 0.1-0.3 % of fluxing agent, 0.1-0.3% of oxidizer, 0.1-0.3% of welding flux, 5-6% of adhesive and the rest is water retention agent; wherein, a layer of the colloidal silver powder of colloidal material is coated on the silver powder at the periphery, the silver powder is a sphere with the grain diameter being 5mum-15mum. After being modeled and dried, if the shape is not satisfactory, the sliver clay component of theinvention can be added with water for softening and be remodeled until the shape is satisfactory.
