Hexagonal boron nitride (hBN) has a layered structure, with strong, intra-layer covalent bonding and weak, inter-layer van der Waals bonding. As a result hBN has low overall hardness that allows it to be commonly utilized as a solid medium lubricant, often referred to as ‘white graphite’, under high temperature and highly oxidizing conditions [3].

cBN Powder 0.5 µ micron size on average - under pressure - transforms into Hexagonal Boron Nitride!!
I just ordered 400 milliliters to add to the car. So the car takes about 7 liters of oil and I want 10% as boron nitride. So I added some before not that long ago... it should still be "in the engine."
I'm seeing "high purity" boron nitride rated at
<0.5 μm
or .5 microns on average.
High-energy shaker milling of hexagonal boron nitride (hBN) powders was used to produce powders... milled hBN and 50 vol. % of 0.5 μm diameter cBN crystals.
The only case where you can see a small part of the ceramic particles in the filter is if it is an old and very dirty filter - because this creates a so called "filter cake" and this cake reduces the size of the filter mesh many times over, so that a very small part could be visible...
He patented his manufacturing process?
He says it's 50% boron nitride and 50% base oil. Fascinating.
So that is 200 milliliters of boron nitride at less than .5 microns?
200 grams of that stuff would cost $200! So that's a steal price... (if it's true).... I guess it's actually 20 milliliters - not 200 milliliters!
the increased surface area (and moisture content) of the <0.5 μm cBN samples is responsible for the lower temperature onset of transformation compared to the 2–4 μm and 35–45 μm powders.
He says in this vid 20 grams of boron nitiride for a 2 liter engine?
20 grams=20 milliliters.
So I ordered 40 milliliters of boron nitride from what I can tell.
Yeah it's about 1.5 ounces? So that's about the market price for the stuff.

In the tests on the four-ball apparatus, the best results were obtained for the oil containing 2% h-BN.
I'll add just HALF the bottle then! Awesome.
