1. The lubricity of boron nitride Boron nitride came out more than 100 years ago. Its earliest application polymorph is hexagonal boron nitride as a high-temperature lubricant, abbreviated as: h-BN, or a-BN, or g-BN (that is, graphite boron nitride), Hexagonal boron nitride is absolutely smooth, and the friction coefficient between the powders is very low. Each layer of its atomic structure contai...

Fisher's method is a relatively simple particle size measurement method, which is based on measuring the speed of air passing through the powder accumulation, and then obtaining the average particle size of the powder according to the Kozeny-Carman formula. However, the Fisher method is a relative measurement method, which cannot accurately determine the true particle size of the powder, and is on...

This is a method of synthesizing boron nitride by reacting borax and ammonium chloride as the main raw materials in an ammonia atmosphere. The two raw materials should be dehydrated and recrystallized separately before participating in the reaction. Borax is best dehydrated in a vacuum at 200~400°C. The recrystallization of ammonium chloride is to dissolve it into a saturated solution, filter to r...

The synthesis of boron nitride by nitridation with boron anhydride (B4O3) is one of the important methods for industrial production of boron nitride. Due to the low melting point of boron anhydride (glass state is 294°C, crystalline state is 450-600°C), it becomes a high-viscosity melt at the nitriding temperature, which hinders the flow of ammonia and makes the reaction slow and extremely incompl...
