摘要： Method for the production of a finely crystalline boehmite and application of said boehmite as flame retardant in plastics. The method involves mixing aluminum monohydrate with a boehmite crystal structure in water to form an aqueous dispersion of said aluminum monohydrate in said water, and then grinding the dispersion while maintaining the dispersion in a pH range of 2 to 4 and forming boehmite seed crystals. The boehmite seed crystals can then optionally be mixed with a hydrate and a basic aqueous solution to form a dispersion which may be heated to convert at least a substantial portion of the aluminum monohydrate to boehmite.

摘要： A flame retardant polymer composition consists of a) 20–60 percent by weight of a thermoplastic and/or cross-linked or cross-linkable elastomer and b) as a flame retardant agent 40–80 percent by weight either of an aluminum hydroxide with the material values specific surface according to BET 3–5 mg2/g mean grain size d50 1.0–1.5 μm residual moisture 0.1–0.4% oil absorption 19–23% water absorption 0.4–0.6 ml/g or of an aluminum hydroxide with the material values specific surface according to BET 5–8 m2/g mean grain size d50 0.8–1.3 μm residual moisture 0.1–0.6% oil absorption 21–25% water absorption 0.6–0.8 ml/g. A process of producing the flame retardant agent is characterised in that a filter-moist aluminum hydroxide obtained by precipitation and filtration with a mean grain size of 0.8 to 1.5 μm is subjected to mill drying in a turbulent hot air stream in such a way that, while the grain distribution is largely retained, the BET surface is increased by at least 20%.
