What is the difference between silicone and silica?
Silica gel (mSiO2·nH2O) is also known as silica oxide gel and silicic acid gel. It is a transparent or milky-white particle with a moisture absorption capacity of around 40%; it can resist immersion in hydrochloric acid, sulfuric acid, and nitric acid, and comes in both spherical and irregular shapes. The commonly used color-changing silica gel is produced by immersing silica gel in CoCl2 solution and then drying and activating it. Because anhydrous COCl2 is blue, hydrated CoCl2·6H2O appears red. Therefore, the degree of water absorption by the silica gel can be determined based on the color change of the colored silica gel. Chromic silica gel is often used as a desiccant and adsorbent. Silica, on the other hand, is just a pure substance.
The main component of silicone is mSiO2·nH2O, which is a combination of silica and water in a gel-like state; when heated and dehydrated, it turns into silica.

You’re truly well-versed; it seems like you know a lot of things.
Actually, there are things I don’t understand either; it’s all thanks to Baidu. The Internet and forums provide the motivation to learn, and I’ll reply once I understand them. Replying does not mean I originally knew or understood it. But after replying, I understood.
