High aluminium brick - any good?

[P2]

Hi, First post...

I got hands on a nummer of 95 % alumina bricks, 3 g/cm3 indicates a 75% dense material and though alumina is sensitive to thermal shock, it should withstand the temperature rise of a wood fired stove. Anyone got experience of similar bricks?

High heat storage capacity but poor insulation. Will it cool too fast as a result of the increase in thermal conductivity at low temperature?

Thanks.

Most dense firebricks are made of Alumina and Silica around a 2:1 ratio, so they should have some heat resistance. Try one out in a stove firebox and see how it behaves.

Yes, I also plan to use it for the bell as well since the high density will reduce the over all volume occupied by bricks. If it does not suck too much heat from the flame, alumina bricks would withstand the erosion in the riser exeptionally well. Maybe cut the to 3 cm thickness from about 9 cm and insulate the riser outside with insulative fire bricks...
