China wholesale 4n 99.99% High Purity Pseudo Boehmite - 4N 99.99% and 5N 99.999% high purity pseudo boehmite – Zhanchi Detail:

Pseudo Boehmite also known as aluminum hydrated and pseudo monohydrate,non-toxic, tasteless, odorless, white colloid (wet) or powder (dry), crystalline phase high purity, good solubility, strong adhesion, high surface area, large pore size, etc., its water state is thixotropic gel.

The product is roasted at 400 ~ 700 ℃ γ- Al2O3 is widely used as catalyst support, catalyst and adsorbent; Nano scale can be obtained by calcination at 1100 ~ 1200 ℃ α- Al2O3 is widely used as coating additives, high-grade ceramics, efficient catalysts for petrochemical industry, submicron / nano grinding and polishing materials, cosmetics fillers and inorganic membrane materials. It is a new type of material with broad development prospects.

Pseudo boehmite also is the preferred aluminum source for the synthesis of phosphorus aluminum molecular sieves and heteroatom phosphorus aluminum molecular sieves. For the synthesis of phosphorus aluminum molecular sieves and heteroatom phosphorus aluminum molecular sieves, it is best to add phosphorus source and aluminum source together with the addition of oxygen source. In general, the aluminum atom of aluminum salt is not connected with oxygen atom. If it is used as aluminum source, it is difficult to obtain enough oxygen source, so aluminum salt is not used in general. Considering the requirement of uniform dispersion of the reaction mixture, the added aluminum source should preferably be soluble in weak acid or medium strength acid solution, while aluminum trioxide or aluminum hydroxide is only soluble in strong acid or strong alkali solution, which is not conducive to the dispersion of the reaction mixture and is not suitable for aluminum source. Pseudo boehmite can meet the requirements of oxygen source and reaction mixing and uniform dispersion, and is the preferred aluminum source in the experiment

The 4N 99.99% and 5N 99.999% high purity pseudo boehmite produced by alkoxide solution, also known as sb powder, has the characteristics of high purity, low stacking ratio, large pore volume, high specific surface and good gelation. It is mainly used as catalyst carrier, desiccant and adsorbent for processing different shapes; Glass and enamel industry is used as colorant and stabilizer, and it is also a high-quality raw material for ink filler.
