DIY Boron Nitride Thermal Paste (High Performance, Cheap, Bulk)

In this tutorial, I will show you how to make high performance Boron nitride thermal paste for cheap and in bulk at home. I always keep running out of thermal paste and the tubes cost too much. I mostly use thermal paste in my electronic projects for my IGBTs and MOSFETs.

-Boron Nitride powder (smaller the particle size, the better) (I bought from AliExpress)

-Mineral oil / Silicone oil

Gather supplies. Measure boron nitride powder. Keep the ratio of powder between 60-70%.

carefully add mineral oil to powder.

For example: 5.8g oil to 10g powder.

Mix throughly until a homogeneous mixture is formed. Make sure you paste is not too dry. It should be easy to spread.

Clean the heat sink with isopropyl alcohol before applying thermal paste to it.
