Plasma treatment to improve the quality of nano bismuth oxide

Bismuth oxide is an important functional powder material, widely used in inorganic synthesis, electronic ceramics, chemical reagents and other fields, mainly used in the manufacture of ceramic dielectric vessels, can also be used in the manufacture of piezoelectric ceramics, varistors and other electronic ceramic components. Due to the finer particle size of nanometer bismuth oxide, in addition to the properties and applications of bismuth oxide powder with general particle size, it can also be used in occasions with special particle [...]

Preparation of hexagonal flake nano magnesium hydroxide materials

Magnesium hydroxide is a kind of green, low-cost and environment-friendly inorganic additive flame retardant. It has the advantages of good thermal stability and non-toxicity. It can be widely added to polymer materials such as plastics, rubber and coatings to improve their flame retardant properties. However, the hexagonal flake-like nanometer magnesium hydroxide material with small particle size and low surface polarity has good dispersibility and nanometer activity. In the case of almost no impact on the use of strength, can [...]

Ti3SiC2 can be machined to precisely sized threads and can be made into implants without lubricant Or prosthesis and so on in oral medicine clinical application. Elastic [...]

What is the preparation method of Ammonium paratungstate

The molecular formula of APT crystallization is 5(NH4)2O·12WO3·nH2O(n=5, 7, 11), and its solubility in water is very small, which increases slightly with the rise of temperature. Ammonium secondary tungstate crystallization is the main intermediate product for the preparation of blue tungsten oxide, ammonium tungsten bronze and tungsten powder, and its morphological structure greatly affects the morphology and properties of tungsten products. The particle size and loose packing density of tungsten products are dependent on the raw material ammonium secondary [...]

The invention relates to a preparation method and a process of ammonium fluotitanate

Ammonium fluotitanate, also known as ammonium hexafluorotitanate, is commonly used in ceramics and glass as an anti-corrosive cleaner and in the manufacture of artificial gems; In addition, it can also be used to synthesize the titanium oxide precursor with special morphology. Ammonium fluoride titanate powder is stable at room temperature and insoluble in water. In the existing preparation methods of ammonium fluoride, the raw materials used are usually more complex, the cost is higher, and the preparation method is [...]

Vanadium carbide and its preparation method and process

The process control of the crystallization of ammonium dimolybdate and the process conditions for the formation of single crystal

Ammonium molybdate is a typical homopolybdate with many types, mainly including ammonium dimolybdate, ammonium tetramolybdate, ammonium heptamolybdate, ammonium ocmolybdate, ammonium dodecolybdate and ammonium tetramolybdate. Ammonium molybdate used in the industry is mostly the mixture of the above ammonium molybdate in different proportions, which is easy to be hygroscopic and agglomerated, and not easy to disperse. Ammonium molybdate is the main raw material for preparation of molybdenum-based products, especially molybdenum powder. Its phase purity and chemical and physical properties have [...]

Preparation of tungsten chloride

This procedure is exactly the same as the preparation of tungsten tetrachloride, but the product cannot contact with air due to its strong hygroscopicity, so it should be fully dried and preserved. Under this reaction condition, there is no protective atmosphere, so it is difficult to ensure that tungsten pentachloride is not decomposed. During refining, the product is put into a hard glass tube and placed in the air of vacuum or nitrogen and carbon dioxide. The glass tube [...]
