Nano calcium carbonate appears as a white powder or granules, odorless and tasteless. Nano calcium carbonate is a new type of ultrafine solid material.
Silicon nitride (Si3N4) is an important structural ceramic material. Silicon nitride has high hardness, wear resistance, oxidation resistance, and high-temperature resistance.
Nano samarium oxide appears as a light yellow powder and is a high-purity, uniform particle size inorganic chemical product. Nano samarium oxide exhibits excellent electrical conductivity, high-temperature resistance, and corrosion resistance.
Light yellow or yellow-brown powder, high purity, fine particle size.
This product is a light yellow powder with high purity, large specific surface area, and low density. It is insoluble in water and alkali, and slightly soluble in acid.
Boron oxide is a colorless glassy crystal or powder. It has a hard and brittle surface, is soapy, and odorless. It is stable when heated or at white heat, even if it is not reduced by carbon. However, it can be reduced to elemental boron by alkali metals, magnesium, and aluminum.
High purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density.
1. Fine particle size, high purity, large specific surface area, and good dispersibility. 2. Stable crystal phase, high hardness, and good dimensional stability.
High-purity nano magnesium oxide is prepared by plasma gas combustion method, featuring high purity, small particle size, uniform distribution, large specific surface area, clean surface, and no residual impurities. It has a low bulk density, making it easy to disperse. The small size effect, surface effect, quantum size effect, and macroscopic tunneling effect are present. After surface modification treatment, there is no hard agglomeration phenomenon, resulting in better dispersibility and higher nano activity in the system. This enhances the special properties of nano magnesium oxide particles in terms of light, electricity, magnetic field, heat, and quantum effects, significantly improving the performance of traditional products and endowing them with new functionalities.
This product is a white loose powder of nano titanium dioxide photocatalyst.
Anhydrous aluminum fluoride is a sandy powder that is difficult to dissolve in water, acids, and alkaline solutions, and is very stable in nature. Wet aluminum fluoride is a white powder with needle-like crystalline structure, slightly soluble in water, and has a higher solubility in hydrofluoric acid solution.
Magnesium fluoride is a white powdery crystal. It is soluble in nitric acid, but poorly soluble in water and alcohol. Its melting point is 1263°C, and it has a density of 3.14. The heat of formation is 263.5 kilocalories per gram-molecule, and it exhibits a weak purple fluorescence under electric light.
