Product Introduction：  

Our company has been focusing on the field of polishing powders for many years. Currently, we have two major series: JingPolish (J-series) and MeiPolish (M-series), comprising more than 40 different types of polishing powder products. The M-series include products with a median particle size of around 2.0 and above, while the J-series include products with a median particle size below 2.0. These two product lines are widely used in various fields such as optical glass, liquid crystal displays, photomasks, crystal jewelry, and stone materials. They are known for their high stability, excellent suspension properties, high cutting rate, and good surface quality. In addition to the existing products, we can also customize products with different compositions, hardness levels, and colors based on customer requirements, catering to diverse application needs.

Polishing powders are typically composed of components such as cerium oxide, aluminum oxide, silicon oxide, iron oxide, zirconium oxide, and chromium oxide. Different materials have different hardness levels and chemical properties in water, making them suitable for different usage scenarios.

Cerium-based rare earth polishing powder is one of the most important rare earth products. Its advantages include strong cutting ability, short polishing time, high polishing precision, high smoothness, long service life, and a clean operating environment. As a result, it is considered superior to other polishing powders and is often referred to as the "king of polishing powders."

Cerium oxide polishing powders can complete a lens polishing that require 30 to 60 minutes using conventional iron oxide polishing powders in only 1 minute. Therefore, rare earth polishing powders have the advantages of lower consumption, faster polishing speed, and higher efficiency. They can also contribute to higher polishing quality and cleaner operating environment. Generally, cerium-based polishing powders mainly contain cerium-rich oxides. Cerium oxide is highly effective as a polishing compound because it can polish through both chemical decomposition and mechanical friction simultaneously.

Applications：

Rare earth polishing powders are widely used for polishing purposes in various industries, including crystal, optical glass, optical lenses, TFT thinning, hard disk glass, liquid crystal displays, flat panel glass, mobile phone screens, touch screens, precision optical glass, semiconductor chips, photomasks and more.
