Preparation method of soluble Mg2Si-radical high-strength light-weight balls for oil-gas fracturing

The invention relates to a preparation method of soluble Mg2Si-radical high-strength light-weight balls for oil-gas fracturing. A prepared Mg2Si nano bulk material serving as a fracturing ball material used during fracturing is high in mechanical strength and light in weight, the compression strength is up to 1640Mpa, Young's modulus is up to 120Gpa, density is about 1.95g/cm , the material can be gradually naturally dissolved after fracturing operations are completed, and defects of traditional fracturing materials can be solved completely.
