ABSTRACT:
Calcium silicate insulation is formed by a process which involves the transfer of the calcium silicate crystals from an autoclave to a holding vessel at a flow rate selected to minimize or prevent damage to the reaction product and through a flow passage such that heat can be removed from the reaction product to stabilize the reaction product prior to its arrival at the holding tank. The calcium silicate material produced by this process is particularly suitable for use as high temperature insulation and has a porosity of in excess of 84% and a permeability to gas of about 0.01% or less. The thermal conductivity of the reaction product is substantially lower than prior art calcium silicate insulations at high temperature.
