Again, fully drained and refilled, just about any coolant will work (within certain bounds, such as ones that attack aluminum)........ The problems with gelation occur when different chemistry coolants are mixed (topping off, partial refill after slight dump, etc.). If you are not fully emptying the system, you need to be careful......
And no antifreeze contains silica, which is an insoluble inorganic (read it's like a rock) material; but many use silicates (potassium silicate to be exact) which is water soluble, an excellent pH buffer, and metal chelating agent..............
