This invention discloses a high-gloss antibacterial ceramic glaze and its preparation method, relating to the field of ceramic glaze technology. By weight, its raw material composition includes: 75-85 parts of base glaze, 8-10 parts of antibacterial system, 6-10 parts of nucleating agent, 3-8 parts of colorant, 1.5-3 parts of auxiliary agent, 0.2-1.5 parts of functional additive, and 0.5-1.5 parts of nano-glossing agent. The functional additive is a compound of graphene quantum dots, quaternary ammonium salt modified montmorillonite, and rare earth carbonates in a weight ratio of (0.02-0.08):(0.1-0.3):(0.1-1). This ceramic glaze achieves a balance of high gloss, efficient and long-lasting antibacterial effect, and excellent glaze quality.

The application discloses a kind of stable indometacin tablets and its preparation process, belong to pharmaceutical preparation technical field.The tablet is composed of indometacin, hydroxypropyl beta-cyclodextrin, soybean phospholipid, composite stabilizer, binder and lubricant, and the composite stabilizer is compounded by succinylated c14-c18 alkyl sulfonate sodium, N-ethyl-L-glutamine and maltodextrin according to specific mass ratio.Preparation process includes liposome inclusion compound preparation, mixing granulation, drying whole particle, total mixing and tabletting.The application realizes the preparation of high drug loading design, and the composite stabilizer forms a multilayer coating protection system with hydroxypropyl beta-cyclodextrin and soybean phospholipid, which synergistically improves the dissolution performance and stability of the preparation, makes the dissolution rate of the preparation fast, and the content of the main component decreases little during long-term storage, solves the problems of low drug loading, poor stability and dissolution of existing indometacin tablets.
