Silicone is a term used for a variety of products with the following chemistry:
A durable synthetic resin with a structure based on chains of alternate silicon and oxygen atoms, with organic groups attached to the silicon atoms.
Sealant is a term based on the verb to seal, meaning a product designed to keep out a fluid, usually water.
Caulk as a noun mean A waterproof filler and sealant, used in building work and repairs. Caulk as a very refers to the installation of caulk.
So caulk and sealant appear to be essentially identical, whereas silicone is a type of sealant or caulk.
How to select the right material. Read the labels very carefully, there are thousands of sealants and caulks out there, they typically are designed for different applications, they have different warranties, different lifespan, different costs, and different application techniques. Only the manufacturer can tell you what type of application they will work on, and sometimes the manufacturers do not tell you the whole story.
