    摘要： A material is presented that exhibits excellent corrosion resistance to supercritical ammonia and is suitable for a supercritical ammonia reactor. An Ni-based corrosion resistant alloy includes from 15% or more to 50% or less by mass of Cr and any one or both of Mo and W, wherein a [(content of Mo)+0.5×(content of W)] is from 1.5% or more to 8.5% or less by mass, a value of 1.8×[% content of Cr]/{[% content of Mo]+0.5×[% content of W]} is from 3.0 or more to 70.0 or less and the balance is Ni and an unavoidable impurity. The alloy may be used to configure a supercritical ammonia reactor or the material is coated on a surface that contacts with a supercritical ammonia fluid. The alloy exhibits excellent corrosion resistance to supercritical ammonia and a mineralizer added the supercritical ammonia. The safety and reliability of an apparatus can be improved, the producing cost can be reduced, the apparatus lifetime can be extended and the running cost can be reduced.

    摘要： An object of the present invention is to manufacture single crystals of high quality on an industrial production scale by preventing impurities from being mixed in single crystals when the single crystals are produced by the solvothermal method.A pressure vessel body 1, in which a supercritical state is maintained, is made of heat resistant alloy, a portion of the pressure vessel body is open, a corrosion-resistant mechanical lining 5 is provided on an inner face of the pressure vessel and on an entire outer circumferential edge of the opening, and the opening is sealed by an airtight mating face formed out of a corrosion-resistant mechanical lining, which is formed on the outer circumferential edge of the opening, and by an airtight mating face of the corrosion-resistant mechanical lining cover 6 on an inner face of the cover 3 through a corrosion-resistant gasket member. Since the pressure vessel body and the inner face of the cover are covered with the corrosion-resistant mechanical lining, corrosion can be prevented. The corrosion-resistant mechanical lining ensures the sealing property on the airtight mating face between the pressure vessel body and the cover and further effectively prevents corrosion in the airtight sealing portion and it becomes possible to repeatedly open and close the airtight sealing portion.
