High temperature structural insulating material
Abstract
A high temperature structural insulating material useful as a liner for cylinders of high temperature engines through the favorable combination of high service temperature (above about 800°C.), low thermal conductivity (below about 0.2 W/m°C.), and high compressive strength (above about 250 psi). The insulating material is produced by selecting hollow ceramic beads with a softening temperature above about 800°C., a diameter within the range of 20-200 $$\mu$$m, and a wall thickness in the range of about 2-4 $$\mu$$m; compacting the beads and a compatible silicate binder composition under pressure and sintering conditions to provide the desired structural form with the structure having a closed-cell, compact array of bonded beads.
