Nickel Hydrazine Nitrate
Nickel hydrazine nitrate (NHN), (chemical formula: i(N2H4)3NO3)2 is an energetic material having explosive properties in between that of primary explosive and a secondary explosive. It is a salt of a coordination compound of nickel with a reaction equation of 3N2H4·H2O + Ni(NO3)2 →〔Ni(N2H4)3〕(NO3)2 ＋ 3H2O File:Nickel Hydrazine Nitrate.jpg, Properly made (talcum powder like consistency) File:Nickel hydrazine nitrate sample 2.jpg, Improperly made (Hard chunks, grains of sand consistency) Preparation NHN can be synthesized by reacting nickel(II) nitrate hexahydrate with a dilute aqueous solution of hydrazine monohydrate at 65 C. To help speed the drying of the product after filtration from the hot water, it can be rinsed with alcohol. The product is a fluffy powder (density=0.9 g/cm3). To increase its bulk density to (1.2 g/cm3), dextrin in the amount of (1%) of the weight of the nickel(II) nitrate hexahydrate can be added. Non-primary explosive deto ...

Normalhöhennull
' ("standard elevation zero") or NHN is a vertical datum used in Germany. In geographical terms, NHN is the reference plane for the normal height of a topographical eminence height above mean sea level used in the 1932 German Mean Height Reference System ('). The plane is in the shape of a quasi-geoid. The reference height is a geodetic, fixed point on the New Church of St. Alexander at Wallenhorst in the German state of Lower Saxony. The geopotential height of this point was calculated in 1986 as part of the United European Levelling Network (UELN), based on the Amsterdam Ordnance Datum. Definition The NHN plane is a theoretical reference plane. It is derived by deducting normal heights from the normal plumb line. The difference between the resulting quasi-geoid and the reference ellipsoid is called the height anomaly or quasi-geoid height. Change-over from NN to NHN Since 1 January 2000 the whole of Germany has changed its height system over to normal heights based on ...
