1. An article of manufacture for heat absorption, comprising:

  • (a) a flight data recorder that includes electronics that are sensitive to heat;

    (b) hydroxide having a formula of Mx(OH)y, wherein “

    M”

    is selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, beryllium, aluminum and ammonium, and wherein “

    x” and



    y”

    are integers, said hydroxide being provided in an amount sufficient to effect a level of heat absorption so as to protect the electronics within the flight data recorder from damage based upon exposure to a predetermined level of heat exposure;

    (c) support means for supporting said hydroxide, said hydroxide being supportable in relation to the flight data recorder by said support means;

    wherein said hydroxide effects said level of heat absorption at least in part based on an irreversible decomposition of said hydroxide; and

    wherein irreversible decomposition of the hydroxide forms a thermal insulation oxide layer around the flight data recorder.
