The lanthanum-cerium co-doping bismuth vanadate pigment prepared by the invention has the advantages that the improvement of the color generating performance of the bismuth vanadate pigment is facilitated through the doping of lanthanum and cerium.

The invention relates to quasi graphene oxide, quasi graphene and a quasi-graphene-based pearlescent pigment based on the quasi graphene oxide or quasi graphene. The quasi graphene oxide is obtained from the following steps: (A) oxidizing flake graphite powder with potassium permanganate; (B) intercalating concentrated sulfuric acid to oxidized graphite powder; and (C) peeling intercalated graphite powder, washing the obtained product till the product is neutral, and performing filtration and drying. Quasi graphene is prepared by reducing quasi graphene oxide. The quasi-graphene-based pearlescent pigment based on the quasi graphene oxide or quasi graphene is high in covering power and chroma and pure in tone, is controllable in technology, and can be widely applied to cosmetics, synthetic leather, plastics, textile and garment or paint.

The invention discloses a lanthanum, yttrium and cerium co-doped bismuth vanadate inorganic pigment and a preparation method thereof. The general formula of the inorganic pigment is Bi1-x-y-zLaxYyCezVO4, wherein x is not less than 0.02 and not more than 0.1, y is not less than 0.02 and not more than 0.1, and z is not less than 0.02 and not more than 0.1; chelating agents are utilized for assistance, and a microwave hydrothermal method is used for preparing the lanthanum, yttrium and cerium co-doped bismuth vanadate pigment; the different chelating agents are added so as to be favorable for slow release of metal ions in a reaction process, thereby enabling the generation process of the lanthanum, yttrium and cerium co-doped bismuth vanadate pigment to proceed more mildly; the microwave hydrothermal method is used to shorten the preparation time; and the doping of the prepared lanthanum element, yttrium element and cerium element is favorable for improving the color-forming performance of the bismuth vanadate pigment.

The invention relates to low-temperature bright red ceramic glaze and a preparation method thereof. The glaze comprises the main components of, by weight, 50-60 parts of PbO, 15-30 parts of SiO2, 10-20 parts of B2O3, 1-5 parts of Na2O, 1-5 parts of ZnO, 0.5-1.5 parts of CaO and 5-6 parts of inclusion red; the binder comprises red lead powder, quartz powder, sodium borate, boracic acid, calcium carbonate, zinc oxide and sodium silicate, the inclusion red is taken as a coloring agent, and the non-frit low-temperature bright red ceramic glaze is prepared. The glaze overcomes the defects that the preparation technology of frit glaze is complex, the melting temperature is high, the appearance and the performance of the glaze are unstable, and the glaze have to be fired in a reducing atmosphere. The low-temperature bright red ceramic glaze has the advantages that the color tone is pure, the glaze face is smooth and level, the glossiness is high, the glazing method is simple, and the sintering temperature range is wide. The glaze is ideal glaze for firing high-quality ceramic products.

The invention relates to a method for controlling the fertilizer appearance by double-caramel pigment. In the fertilizer production process, the operation is carried out according to the following steps that (1) firstly, the double-caramel pigment and the water are taken according to a mass ratio being 1:0-0.5 and are mixed and stirred uniformly; (2) the double-caramel pigment uniformly mixed in the first step is conveyed into a slurry neutralizing tank by a plunger type mechanical metering pump, a plunger type diaphragm metering pump or a miniature single screw rod pump to be fully stirred with fertilizer slurry, in addition, the double-caramel pigment is completely dissolved and mixed uniformly, one ton of added double-caramel pigment fertilizer consumes 0.1 to 5.0 kg of double-caramel pigment, and a variable frequency flow meter is used for metering; and (3) the fertilizer slurry mixed with the double-caramel pigment is pelletized, and the fertilizer in the required color is prepared. The method has the advantages that the fertilizer appearance can be conveniently regulated and controlled through the double-caramel pigment, the fertilizer color is uniform and stable, the color mixing of fertilizers cannot occur, in addition, the consumption is low, the cost is low, the biodegradable effect is realized, the environment is favorably protected, the operation is convenient, no pollution, no poison and no public hazard exist, and the like.
