RE:Longs remember why we are invested in HPQ!!

Alright I have to ask a dumb question here because I do not seem to be able to get a direct answer on Google. Just trying to learn what future possibilities may or may not be.

What is the difference between silicon powders that are being talked about here at HPQ and silicon carbide powders that can be used in high power applications?

What is the difference between silicon and silicon carbide?:

 

 

"Silicon has a breakdown voltage of around 600V, while silicon carbide can withstand voltages 5-10 times higher. What this means in practice is that high-power applications will be able to utilize semiconductor technology, or that a device of the same voltage difference can get nearly ten times smaller."


As the U.S. talks about going green, one of the things you never really hear about is the use of "small Natrium nuclear reactors". The big boys such as Bill Gates in Kemmerer, Wyoming as well as Jeff Bezos and Warren Buffet are all funding small nuclear reactor projects. Silicon has a use in  those small reactors but I cannot determine if that would be an HPQ silicon powder or just silicon carbide powder.

X-Energy uses Helium.

Silicon carbide (SiC) has been studied and utilized in nuclear systems for decades. Its primary use was, and still is, as the micro pressure vessel for high-temperature gas-cooled reactor fuels. For these so-called TRI-ISOtropic (TRISO) fuels, the SiC is deposited via a gas-phase decomposition process over two layers of pyrolytic graphite surrounding the fuel kernel. In addition to being strong enough to withstand the pressure buildup from the fission product gas liberated, this SiC layer must also withstand chemical attack from metallic fission products such as palladium and the mechanical loads derived from irradiation-induced dimensional changes occurring in the pyrolytic graphite. More recent nuclear applications of SiC include its use as structural composites (i.e., SiC/SiC) for high-temperature gas-cooled reactors and for fusion power systems. The possibility of using composite and monolithic SiC thermal insulators for both fusion and fission systems is also being investigated. Moreover, both monolithic and composite forms of SiC are being investigated for use in advanced sodium fast, advanced liquid salt-cooled, and advanced light water reactors.
