Sodium chloride is a white odorless crystalline powder. It has a melting point of 801 ° C and a boiling point of 1465 ° C. It is slightly soluble in ethanol, propanol and butane. It becomes a plasma after being miscible with butane, and is easily soluble in water. The solubility in water is 35.9 g (room temperature). NaCl is dispersed in alcohol to form a colloid, and its solubility in water is reduced by the presence of hydrogen chloride, and it is hardly soluble in concentrated hydrochloric acid. It is odorless and salty and easy to deliquesce.

Titanium carbide ceramics are typical transition metal carbides. Its bond is composed of ionic bonds, covalent bonds and metal bonds in the same crystal structure, so TiC has many unique properties. The structure of the crystal determines the basic characteristics of TiC with high hardness, high melting point, wear resistance and electrical conductivity.
Light gray, cubic crystal system, insoluble in water, with high chemical stability, almost no chemical reaction with hydrochloric acid, sulfuric acid, but soluble in aqua regia, nitric acid, and hydrofluoric acid, also soluble in alkaline In the solution of the oxide.
Metal stainless steel powder made of a stainless steel alloy.
The particle shape of stainless steel powder was a regular spherical shape with a density of 7.9 g/cm 3 and an average particle diameter of <33 μm. It has good corrosion resistance and durability. Its spherical particles can be positioned parallel to the surface of the coating film and distributed throughout the coating film to form a shielding layer with excellent hiding power to block moisture.
Pure titanium is a silvery white metal with many excellent properties. Titanium has a density of 4.54 g/cm3, which is 43% lighter than steel and slightly heavier than the long-established light metal magnesium. The mechanical strength is similar to steel, twice as large as aluminum and five times larger than magnesium. Titanium is resistant to high temperatures and has a melting point of 1942K, which is nearly 1000K higher than gold and nearly 500K higher than steel.
Titanium looks like steel, has a silver-gray sheen, is a transition metal that has been considered a rare metal for some time. Titanium is not a rare metal. Titanium accounts for about 0.42% of the total weight in the earth's crust, which is 16 times the total amount of copper, nickel, lead and zinc. Ranked seventh in the metal world, with more than 70 minerals containing titanium. Titanium has high strength, low density, high hardness, high melting point and strong corrosion resistance; high-purity titanium has good plasticity, but becomes brittle and hard when impurities are present.
Mercury-II-chloride, the molecular formula is HgCl2, colorless or white crystalline powder, a small amount of volatile at room temperature. Soluble in water, ethanol, ether, methanol, acetone, ethyl acetate, insoluble in carbon disulfide, pyridine. Long-term work in an environment where the mercury vapor content in the air exceeds the allowable range can cause chronic poisoning, and there are mental disorders such as memory loss, salivation, fatigue, fatigue, insomnia, and dizziness. Heavier fingers and tongue tremors appear. After poisoning, the stomach should be washed.
Mercury oxide(mercury oxide (II)) is an alkaline oxide, inorganic, chemical formula HgO, bright red or orange-red scaly crystal or crystalline powder, almost insoluble in water, insoluble in ethanol, at 500 ° C break down. Very toxic and irritating. Mercury oxide can be used to make other mercury compounds, as well as catalysts, pigments, antibacterial agents and electrode materials in mercury batteries.
Manganese carbonate is a raw material for the manufacture of soft ferrites for telecommunications equipment, synthesis of manganese dioxide and manufacture of other manganese salts. Used as a catalyst for desulfurization, pigments for enamels, coatings and varnishes. Also used as a fertilizer and feed additive. Used in medicine, welding electrode accessories, etc., used as raw materials for the production of electrolytic manganese metal.
