The invention discloses a high-water-solubility L-ascorbic acid-2-phosphate calcium sodium salt as well as a preparation method and application of the high-water-solubility L-ascorbic acid-2-phosphate calcium sodium salt. The 1% aqueous solution of the calcium sodium salt is free of precipitation after standing at 25 DEG C for 24 hours, and the 600 nm light transmittance of the 0.1% aqueous solution is greater than or equal to 95%. The preparation method comprises the following steps: reacting L-ascorbic acid with sodium trimetaphosphate to generate AMP sodium salt, slowly dropwise adding calcium lactate or calcium gluconate at low temperature, adding 0.1-0.5 wt% of sodium citrate as an anti-precipitation protective agent, and carrying out low-temperature spray drying (inlet air is 150-170 DEG C and outlet air is 65-75 DEG C) and cold nitrogen cooling to obtain the product. The product is specially applied to water sprinkling for aquaculture, can be completely dissolved within 30 seconds under the concentration of 10g / L, is clear and transparent in solution, effectively solves the problems of slow dissolution, turbidity and precipitation of the traditional AMP calcium sodium salt during water sprinkling, and remarkably improves the biological utilization efficiency.

White, translucent, colourable ceramic compound based on a calcium sodium frit that devitrifies sodium anorthite in the SiO2—Al2O3—CaO—Na2O system to be used as the main raw material (60%-90%) in porcelain stoneware compositions for the production of large format sheets (up to 2 metres). The frit will provide parts with an elevated whiteness without the need to introduce opacifiers such as zirconium silicate, although these could also be added, together with aluminas, to obtain a higher level of whiteness. On the other hand, it will provide the ceramic compound a high translucency, which will allow it to have a high colour development with the addition of inorganic pigments.

The invention discloses high-oil-loading temperature-sensitive biphase gel as well as a preparation method and application thereof, and belongs to the technical field of biomedical materials and cosmetics. The gel is prepared by taking a long-chain alkyl grafted and modified polymer matrix as a basis and reacting with an inorganic cross-linking agent calcium sodium borosilicate. The preparation method comprises the following steps: reacting the component A with the component B in a solvent to obtain a hydrophobically modified polymer matrix; and then mixing with calcium sodium borosilicate in water, and forming gel under the synergistic effect of a physical crosslinking point formed by hydrophobic aggregation of an alkyl chain and ionic crosslinking. The oil carrying capacity of the gel is improved, and the oil carrying capacity can reach 20 wt% or above. Besides, by introducing an alkyl chain, a polymer chain can generate chain curling and intermolecular association in water along with temperature rise, the effect is synergistic with ionic crosslinking, the gel is endowed with a temperature-sensitive characteristic, the gel generates reversible sol-gel conversion near the body temperature, and in-situ fitting with the skin or a wound surface is realized. The application potential is realized in the fields of drug sustained-release dressings and functional cosmetics.
