Abstract

The invention relates to a preparation method of a ceramic microbead grinding medium, belonging to the technical field of ceramic molding. The present invention firstly uses kaolin, silicon carbide, lime clay etc. as raw materials, and ball mills after mixing to obtain a mixed powder; then mixes the mixed powder and water to obtain a slurry; adds egg white and sucrose respectively to the slurry, After mixing, stir to obtain a foamy slurry; ballize the foamy slurry and fire to obtain hollow ceramic microspheres, and grind the hollow ceramic microspheres to obtain hollow microspheres with a rough surface; then use Fe, Mn, Mo, etc. as The raw materials are heated and melted to obtain a mixed metal liquid, the hollow microspheres with rough surfaces are soaked in the mixed metal liquid, taken out, naturally cooled to room temperature, dried and polished. The ceramic microbead grinding medium prepared by the invention has high hardness, low wear resistance rate and good wear resistance.

Description

technical field [0001] The invention relates to a preparation method of a ceramic microbead grinding medium, which belongs to the technical field of ceramic molding. Background technique [0002] Ceramic grinding media has the advantages of high mechanical strength, high hardness, high density, good high temperature performance, no pollution to materials, strong acid and alkali corrosion resistance, and excellent wear resistance, making it occupy a very important place in the field of grinding media. It is widely used in fine processing fields related to minerals, chemicals, paints, machinery and electronics. [0003] In my country's current market, ceramic beads mainly include alumina, zirconia, silicon carbide, silicon nitride and other varieties, among which ZrO 2 Ceramic balls and high alumina ceramic balls (75-95% Al 2 o 3 ) is the main supply and demand object in the market. But ZrO 2 and Al 2 o 3 The price is expensive, the manufacturing cost is high, and there...
