US20060068112A1 - Recycling process for boron …

A process for recycling boron nitride paint or powder is provided. Boron nitride paint or powder is removed in an acid wash to form a wash solution. A caustic is added to the wash solution to form a neutralized wash solution. The neutralized wash solution is filtered to collect a boron nitride cake. The boron nitride cake is then washed and formed into boron nitride paint or powder.
