Abstract

The invention discloses a polishing solution used for precision machining of an optical communication ZrO2 ceramic stub and a preparation method thereof. The polishing solution is composed of 0.5 to 12% of cerium oxides, 0.1 to 4% of aluminum oxide, 0.01 to 0.1% of moisture regulators, 0.05 to 2% of dispersants, 0.01 to 4% of dispersion stabilizers, 0.005 to 0.5% of cosurfactants and the balance of deionized water. The preparation method comprises the following steps of: loading cerium oxides and aluminum oxide into a mixing disperser, adding a part of deionized water and a part of moisture regulators, thoroughly mixing, adding the rest additives and the rest deionized water, mixing again, adjusting pH to 2 to 5, and ultrasonically dispersing. The invention solves the problem of incoordination between polishing efficiency and polishing precision in the conventional CMP process using single inorganic grinding material, achieves the polishing effect which can not be reached by single inorganic grinding material, can not only increase polishing efficiency but also improve polishing precision, and has good application performances.

Description

[0001] technical field [0002] The present invention relates to a kind of polishing fluid for precise processing, particularly relate to a kind of optical communication Zr0 2 A polishing fluid for precision machining of ceramic ferrules and a preparation method thereof. Background technique [0003] In recent years, optical communication has developed extremely rapidly. On the one hand, it is developing in the direction of ultra-high speed, large capacity, and long distance; on the other hand, the optical fiber LAN user system has been vigorously developed. All-optical communication is the inevitable direction of optical communication development.
