We are looking for CBN abrasive wheels for Bench Grinder for sharpening our chef knifes.
These wheels last much longer and keep the knife steel from deteriorating.
But no one seems to have them even though i see people on YouTube from other countries using them.
6inch version with medium and fine grit will work best for us.
With Robin hood opening instant deposits available with dogecoin there is a very big chance for SPIKES tomorrow, we are looking at Big Gains if we Buy in and watch, there will be an increase. Today DOGECOIN went from 0.032 ^ 0.039 that could be the rise that we, who follow Doge have waiting for. The analytics are showing interest for spikes in February based on the numbers, Mark Cuban also bought into Dogecoin today, Elon Musk often refers to DogeCoin as "his favorite cryptocurrency, and many are saying they are pumping in at 9pm Tonight EST
Disclaimer: I am not a financial professional, nor is this financial advise, and I may or may not be mentally impaired. I just really like the the Cryptocurrency.
Can anyone explain to me very quickly (just the steps not an in depth explanation) how to make cubix boron nitride? I'm trying to progress in the armor quest and i could get up to the ender dragon armor if it wasn't for this thing.
If anyone does actually reply to this thank you for your time
I've exhausted all the usual sources trying to find how the bandgap of cubic boron nitride varies with temperature. I've found the room temperature bandgap and the temperature dependence for hexagonal boron nitride. Anyone have any ideas on where to look for data on this or perhaps how to estimate it?
Has anyone used these? I'm looking for something that can effectively reprofile a knife blade and specifically to the angle of the sharpmaker since that is what I use for my touchups (I'm useless with freehanding).
I'm curious how well they actually work and also how well they hold up. Since they are surface only rods (not solid like the ceramics) I know they will have less wearability, but I haven't seen much information about that.
I've seen a few cliff stamp videos about it (he seems to be the only person talking about them) that are very positive... but I get the impression he could sharpen a seagull's bill with a 1976 penny and get it hair popping sharp. So I need to know how us normal folk would hold up using them and how long I can expect it to last with my ham handed technique.
--edit--
Last post asking about sharpening I promise, i just really don't want to screw up my knives. I got an old Native that's half spyder edge and like both my spyderco's the factory grind is too shallow to use my sharpmaker. I just ordered the rods to reprofile my pm2 but i can't find any info about using the sharpmaker as intended to reprofile a spyder edge. I jut see people doing it by hand with the stones sometimes and I do not trust my skill to do this freehand.
There are a ton of sources claiming that hexagonal Boron Nitride is the most thermally conductive electrical insulator. I am wondering if people are confusing the BeO and BN; but there are many contradicting claims (not just on Wikipedia, but all over).
It is also difficult to obtain consistent numbers for the conductivity of either material.
Some snippets from our favorite source of poorly reviewed information, Wikipedia:
https://en.wikipedia.org/wiki/Boron_nitride
>"Aluminum nitride and silicon carbide are about 100 times as thermally conductive, and beryllium oxide has even higher thermal conductivity. Boron nitride has the highest thermal conductivity by far. "
>
>The thermal conductivity of BN is among the highest of all electric insulators
https://en.wikipedia.org/wiki/Beryllium_oxide
> "Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals."
Can anyone help me out here? Beryllium oxide is extremely toxic while Boron Nitride is used in cosmetics. If Boron Nitride is really more conductive, there is zero reason for me to even play with the idea of using Beryllium oxide for a sintering medium.
