The appearance is pure white ordinary thermal conductive silicone grease. Its thermal conductive adhesive is mainly composed of silicon carbide compound, also known as silicon carbide compound. This silicone grease has low density of thermal conductive adhesive molecules and loose links between molecules, so its thermal conductivity is not very good. But its advantage is low manufacturing cost, cheap market price, and most of it is insulated. Unlike other silicone grease containing metal components, it will conduct electricity.
A kind of conductive silicone grease containing gold, but don't think it's gold. It's rare in the market now. In addition, some silicone grease is also gold, but it doesn't contain gold, it's just called in the title.
There is also a silver containing thermal conductive silicone grease, that is, silver compound or silver powder is added to the thermal conductive adhesive to make up for the lack of thermal conductivity of silicon carbide by using the strong thermal conductivity of silver. The appearance of this thermal conductive silicone grease is gray.
TF8 or diamond paste, these two thermal conductivity are sufficient, the price is appropriate, and it doesn't hurt to consume them. I think the cost performance of diamond paste is reasonable, because its decay time is slow, which is better than many high-end toothpastes. No matter how expensive it is, it doesn't make much sense, and its practicability is a bit wasteful.
