TL;DR: A liquid accelerator composition for sprayed concrete, comprising aluminiurn sulphate, amorphous aluminium hydroxide, alkanolamine and an organic dibasic acid anhydride, was proposed in this article.
Abstract: A liquid accelerator composition for sprayed concrete, comprising aluminiurn sulphate, amorphous aluminium hydroxide, alkanolamine and an organic dibasic acid anhydride. The compositions allow the attainment of high early compressive strength, and they can be tailored to give good performance with a wide variety of cement types.

TL;DR: In this paper, a process for preparing aluminium oxide features that the kaolinite and powdered coal ash are predesiliconized to make the Al-Si ratio is greater than 4, the self-breaking sinter method is used, the diluted solution of sodium carbonate is used for extracting, and the complex reaction is used to purify.
Abstract: A process for preparing aluminium oxide features that the kaolinite and powdered coal ash are predesiliconized to make the Al-Si ratio is greater than 4, the self-breaking sinter method is used, the diluted solution of sodium carbonate is used for extracting, and the complex reaction is used for purifying. The pure CO2 gas generated by sintering and NaAl2O3 solution take part in carbonizing reaction to generate aluminium hydroxide. Changing the crystalline structure of aluminium hydroxide can obtain aluminium oxide.

TL;DR: In this article, a safety cable with high effective fire-proof inflaming retarding function is presented, which is mainly formed from (wt%) 68-70% of aluminium hydroxide, 22-24% of cured resin, 2.5-4.5% of epoxy resin and 2.0-3.5 % red phosphorus.
Abstract: The present invention discloses a protective layer for electric cable with high-effective fire-proof inflaming retarding function. It is mainly formed from (wt%) 68-70% of aluminium hydroxide, 22-24%of cured resin, 2.5-4.5% of epoxy resin and 2.0-3.5% of red phosphorus. The aluminium hydroxide is heated, and can be decomposed into aluminium oxide and water so as to produce the oxygen-insulating and temp.-lowering action, so that the inflamed cable can be extinguished. Said invention can provide a safety cable.

TL;DR: In this paper, a method for the preparation of layered double hydroxides with particles having a rod-like morphology by preparing a precursor of rodlike aluminium hydroxide particles and contacting the precursor with an aqueous lithium salt is presented.
Abstract: A method is disclosed for the preparation of layered double hydroxides with particles having a rod-like morphology by preparing a precursor of rod-like aluminium hydroxide particles and contacting the precursor with an aqueous lithium salt. Preferably, the precursor will be prepared by templated hydrothermal synthesis. Also disclosed are lithium aluminium layered double hydroxides with rod-like particles and composites comprising such particles.

TL;DR: The active alumina catalyst can improve selectivity and yield of compound alkyl sulfide and methanethiol as mentioned in this paper, and can be used to improve the selectivity of compounds such as dimethyl sulfide.
Abstract: The invention relates to a catalyst technology, concretely, an active alumina catalyst and its producing method. Components of the active alumina catalyst are: Na 0.8-0.1 percents, Fe<0.1 percent the others are alumina whose purity is over 99 percent. The producing approach is: using aluminium hydroxide powder or (and) bodhmite powder as material; evenly mixing aluminium hydroxide powder or (and) bodhmite with aqua fortis solution deployed by deionized water; forming, drying in 100-150deg.C for 2-8 hours, baking in 400-600deg.C for 3-20 hours, bolstering and getting production. Adopting the invention can improve selectivity and yield of compound alkyl sulfide and alkyl sulfhydrate, esp. dimethyl sulfide and methanethiol.
