The invention provides a preparation method of triclinic-phase NaFe1-xMxSO4F (M=Co, Ni; x=0-1.0). A bulky and porous monoclinic-phase precursor FeSO4.H2O preparation method comprises the steps that: FeSO4.7H2O is sufficiently mixed with insurance powder, and the mixture is heated and ...
Conventionally heated reaction gives a phenol yield of 0.6%. A higher phenol yield of 13.9% with a selectivity of 100% is obtained when the reaction mixture was irradiated with microwave energy. It is concluded that microwave irradiation offers more effective control of energy input for hydroxyl ...
The admixture, in a dry state, is introduced into a preheated oven at about 1450 to 1750 degrees C. for between about one and five hours. Silicon carbide fibers and a sheet formed from the fibers are disclosed.Richard D. NixdorfUS
Conventionally heated reaction gives a phenol yield of 0.6%. A higher phenol yield of 13.9% with a selectivity of 100% is obtained when the reaction mixture was irradiated with micro-wave energy. It is concluded that microwave irradiation offers more effective control of energy ...
A precursor preparation method comprises the steps that: under a vacuum condition, FeSO4.7H2O is heated and dehydrated; nitrogen is delivered in; and heating is carried out, such that a bulky, porous, and pure-phase lithium ion battery positive electrode material precursor FeSO4.H2O is prepared....
