Benefits of technology

This patented technology allows creation of small particles called nanofluorescent materials that can be used with various types of liquids like oils or water without causing damage during use. These tiny particles are very effective at preventing frictional wear between parts when they come into contact due to their unique chemical structure.

Problems solved by technology

The technical problem addressed by this patented technology relates to finding ways for adding small particles called nanoantimers (Nanocrystals) into liquid or solid products with better resistance against wearing damage caused during their operation under harsh environments such as those associated with impact and vibrations.

Abstract

The invention discloses a method of preparing the nano particles of alkali earth fluoride. The method is to dissolve alkaline earth salt and fluoride respectively into reaction medium, then, the alkaline earth salt solution reacts with the fluoride solution for 1-5 hours under room temperature through precipitation method, then the nano-particles can be gotten after filtration, washing and vacuum drying. The invention is simple in operation, low in cost and easy to be popularized in industry; no special process equipment is needed. The nano particles of alkali-earth-fluoride can be taken as grease additives and have good performances of wear resistance, antifriction and extreme pressure resistance.
