Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram.

The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
U.S. manufacturing activity contracted further in December, with a measure of factory output dropping to the lowest level in more than 4-1/2 years amid worries that higher tariffs would raise ...
The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate , 35% urea and only 20% water.
The reports follow calls from China's nitrogen fertiliser association last month to prioritise supplies for domestic use after prices hit a two-year high. The issue has raised concern about a ...

urea + adduct component -> urea adduct. The equilibrium of the reaction is dependent on the concentrations of the reactants, the solvent and the temperature. [12] The necessary quantity of urea for the formation of inclusion compounds varies from about 1 to 0.8 mole of urea per methyl- and methylene group in a carbon chain. [12]
