Any idea what the commercially available materials are, and how the
Johnson ceramic is made? Inquiring minds want to know!
Best,

Could the famous space shuttle tiles be used for nozzle material?
Another possibility is the ceramic material developed by aerospace
engineer GW Johnson. A big advantage of the Johnson ceramic is it can
be homemade from commercially available materials, quite useful for
the amateur rockets.
