There are many types and densities. They cut easily with a rod saw. Drill easily with a masonry bit. Could be turned on a lathe. Can be stacked up with washers between for space. Holes could be drilled through and offset per layer for a zig zag flow of gas. Maybe be good regenerator material.
Have you given any thoughts to fiberglass cloth and very light application of sodium silicate, water glass? How about aluminum oxide fiber cloth?

High temperature displacer
Re: High temperature displacer
I'm not aware of any lightweight low density floor tiles.
I'm not saying they might not exist somewhere, I've just never seen it..
Fiberglass cloth? Hasn't tried it. Medium high temperature.
Not familiar with aluminum oxide fiber cloth.
Re: High temperature displacer
Thanks.
I already have several bats of "ceramic fiber" blankets of various thickness.
Definitely excellent, light weight, high temperature material.

My thinking is too much sodium silicate, and it will be heavy and less temperature resistant. Not enough and it will be too limp. Thinning it with water could change how well it penetrates, soaks in. Thicker would be more a surface seal.

Re: High temperature displacer
All true, but IMO sodium silicate to harden ceramic fiber would probably be unnecessary in many cases. In a cylindrical high temperature displacer chamber in particular, the soft cushiony characteristic could make it form fitting to the hot end of the chamber.
For a flat LTD type design, there is already ceramic foam board which has more rigidity.
Tested in this video.
