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

Vanadium carbide, black crystal, density 5.25-5.4 black crystal, melting point 2750℃, slightly harder than quartz. Mainly used in the manufacture of vanadium steel, can also be used as carbide carbide additive. Can be used in structural steel, tool steel, pipe steel, rebar, ordinary engineering steel and cast iron. The research shows that adding vanadium carbide to steel can improve the comprehensive mechanical properties of steel, such as wear resistance, corrosion resistance, toughness, strength, ductility and hardness as well as [...]

Sodium titanate holds graphene together to create a high energy, high power micro capacitor

With sea urchin sodium titanate as the negative pole and porous activated graphene as the positive pole, what kind of “spark” will be generated when they combine? According to the dalian Institute of Chemical Physics, Chinese Academy of Sciences, wu Zhongshuai’s team and Bao Xinhe’s team worked together to combine “sea urchins” with graphene to develop flexible sodium ion micro-supercapacitors with high energy density and high heat resistance. Micro miniature sensors, micro robot, the power supply system is inseparable from [...]
