How much heat could it take?
What happens to it when it fails?
Has any one tested it?

Looks like it turns to silicone dioxide,that could be useful.

Could silicone caulk be combined with aluminum oxide and slaked lime to form a geopolymer?

I'd think 700 C is more likely for the lower half of the firebox where the glowing coals are. At the very bottom of the box between the coals highest recorded temperature has been 910 C. That would be 1290 F and 1650 F respectively.

Between bricks it'll be quite a bit cooler than the inside wall of the burn box right next to glowing coals.
There is obviously a delta-t from inside the box to the outside; the hottest I've ever measured on the roof (not the ceiling) of my batch box is 200°F. The door, itself, has been up to 700°F. That is after hours of continuous burning.
After taking these measurements, I'm tempted to simply seal up each and every crack with red RTV and see how long it lasts. I'm willing to bet it would do pretty darn well.

I've seen high-temperature silicones in stores rated around 1200C. Some say will shortly tolerate even 1500C.
