Material capable of changing alloy structure and preparation method of material

The invention discloses a material capable of changing an alloy structure. The material capable of changing the alloy structure is prepared by from the components in percentage by weight: 0.3-0.9% ofaluminium hydroxide, 3-8% of sodium acetate, 11-15% of barium nitrate, 0.5-0.9% of sodium dihydrogen phosphate, 13-19% of sodium chloride, 2-7% of potassium chloride, 12-18% of halloysitum album composite ceramic powder, and the balance potassium fluotitanate; holmium-containing rare earth compound and aluminium hydroxide can change the form and the size of a harmful phase formed by impurity elements, metamorphic elements in the halloysitum album composite ceramic composite powder can efficiently refine coarse primary silicon, gas and residues can be removed while metamorphism treatment is conducted, and the melting efficiency is improved. According to the preparation of the material, the clearance among powder raw materials can be shorted by using a method of extrusion calcinations, metalsalts such as sodium, alu
