It was a valiant effort though at explaining ceramic actives.
A full explanation is more detailed and nearly impossible to post here.
“Ceramics” or better stated reactive silane/siloxane chemistry is some graduate level stuff but here are some quick facts: Silicone carbide is never used.
“Ceramic” is a descriptive first given as a layman’s explanation for silane condensation reactions. C-O-Si type bonding appears in ceramic compositions hence the reference. Polysiloxanes are used and do constitute the majority of “ceramic chemistry” as understood in the Detailing industry. These actives are not water soluble and must be supplied in solvent or emulsion form. If not properly catalyzed, reaction rates can be slow and/or require heat. The small bottles used by many suppliers come from the fact that the solvents are flammable. Anything over 3.5 ounces must ship ground.
Low molecular weight silicone makes up most of the “Quick Detailer” products. These products are low viscosity, clear, water based micro-emulsions or cloudy, water based non-reactive.
9H or 7H, references to “Quartz” or “Crystal” elude to hardness. Trouble with this reference is it’s improper terminology as well. The references are derived from the Moh’s hardness test for geologic mineral classification. It’s not applicable to reactive surface coatings but doesn’t seem to bother most selling it.
Pretty much all ceramic coatings are Polysiloxane polymer coatings with nano sized silica particles. There are differences in the exact polymer composition, solvent carriers, and powder size distribution of the ceramic particles. They really are just sealants with particles in them.
What are Polysiloxanes? (https://www.corrosionpedia.com/definition/1842/polysiloxanes)
Polysiloxanes, or polymerized siloxanes, are a polymer with a silicon-oxygen backbone. Its chemical formula is (R2SiO)n , where R is usually methylsiloxanes (CH3), although it can be H or alkyl or aryl group. Polysiloxane has shown greater resistance to the effects of UV radiation than organic polymers containing a carbon-carbon backbone. Polysiloxanes can be oils, greases, rubbers or plastics depending on molecular weight.
Polysiloxanes exhibit:
Superb abrasion and corrosion resistance
Strong chemical resistance
Anti-graffiti properties
Resilience to dirt pickup
Low VOCs (volatile organic compounds)
Here's a study from Research Gate testing the scratch resistance using polysiloxane:
"Many attempts have been carried out to increase the scratch resistance of clearcoats using various appropriate additives. These additives may increase surface hardness or surface slippage, and/or enhance the bulk mechanical strength of the clearcoat.
In the present study, the influence of various added loads of three differently structured polysiloxane additives on the scratch resistances of an acrylic melamine clearcoat was investigated.
A series of analytical instruments, such as a laboratory carwash simulator, a scanning electron microscope and others were used to compare the effects of the various added contents of polysiloxane additives on changes in the viscoelastic properties and scratch morphologies of the resultant clearcoats.
The results illustrated that all polysiloxane additives improve the scratch resistance of such clearcoats, yet the optimum load varied for each individual additive.
There is also a good indication that polyether-modified polysiloxanes improve scratch resistance by increasing surface hardness, while the fluorocarbon-modified polysiloxane tends to change the viscoelastic properties of the clearcoats."(ResearchGate)

Dirt and grime will not stick to the surface of your car and since the hydrophobic effect causes water to bead up and roll off the surface, it will take the dirt with it! The hard ceramic film also offers superior protection from damaging contamination and harsh chemicals.
Durability and length of protection are really where ceramics shine. It can depend on the type of coating you choose & the conditions your car or truck lives in, but I typically see ⠀
1-2 years of protection from a coating like mine 10H, Migliore or CarPro.
That’s more than triple the amount of time when compared to a wax.
They are more difficult to apply and I'd suggest consulting a professional if you choose this investment.⠀
