Product introduction: Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium; It melts at 815 C. The chemical nature of metallic calcium is very active. In the air, calcium is quickly oxidized and masked with an oxide film. When heated, calcium will burn and emit a beautiful glow of brick red. Calcium and cold water have a slower effect, and intense chemical reactions occur in hot water to release hydrogen (lithium, sodium, and potassium can cause intense chemical reactions even in cold water). Calcium is also easily combined with halogens, sulfur, nitrogen, and the like. 1,product name:calcium metal 2,Shape :powder, lump and granulates 3,CAS:7440-70-2 4,Density:1.54g/cm 5,Melting point:850C 6,Boiling point:1440 C(lit.) 7,Application:Wheel keel Product use: At present, in the steel industry, the main use of metal calcium is to process into metal calcium particles, and then to make calcium iron wire or pure calcium wire, and finally used for steel refining outside the furnace, its role is to desulfurization, deoxidation, increase the fluidity of molten steel. Promote the rapid rise of inclusions in molten steel, generally used in the production of high-quality steel; as a dehydrating agent to produce anhydrous alcohol; in the petroleum industry, as a desulfurizing agent, in the metallurgical industry, it is used to deoxidize or desulfurize . However, calcium compounds have a very wide range of uses, especially in the construction industry.

Natural zeolite is a new material, which is used as ion exchange agent, adsorbent, desiccant, catalyst and cement mixture. In petroleum and chemical industry.separation and storage agent hard water softening, seawater desalination agent. In the aspect of environmental protection, it is used to treat waste gas and waste water, remove or recover metal ions from waste water and remove radioactive pollutants from waste water. Main specifications: 1-3mm,3-5mm,>5mm;200mesh,325mesh
Activated 4a zeolite adsorbent powder Xintao Activated Molecular Sieve Powder, has the character of high dispersibility and rapid adsorbability. It is used in some special absorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc. It can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin and some adhesives. It can also be used as desiccant in insulating glass rubber spacer. Typical Application: (a) 2K-Polyurethane coatings and mouldings. (b)1K-Polyurethane storage protection. (c) Storage protection for metallic pigment paint. (d) Polysulfide and silicone systems. (e) Carriers for chemicals for controlled release. (f) Processing aid for polymer production. (g) Desiccant for the production of polymer desiccant materials. (h) Cosmetics additive. (i) Storage protection additives for highly hygroscopic goods. (j) Additives for flame retardants. (k) Shift of chemical reaction by removal of water as by product. Warranty: By National Standard HG/T 2524-2010. The storage time is more than 3 years. Free consultation during the warranty period.

Ferrochrome Ferrochrome is an alloy of chromium and iron containing between 50% and 70% chromium. Ferrochrome is produced by electric arc melting of chromite and chromium ore. Most of the world?s Ferro-Chrome is produced in South Africa which has large domestic chromite resources. The production of steel is the largest consumer of Ferrochrome, especially the production of stainless steel with a chromium content of between 10 and 20%.
Silicon Manganese Silicon Manganese is mostly used in steelmaking and foundry activities. Some 30 % of the manganese used today in steelmaking is still used for its properties as a deoxidant and a sulphide former. In this last case it combines with sulphur avoiding the formation of iron sulphides, which sulphides are low melting point phases which become liquid at hot rolling temperatures and which, consequently, generate surface cracking. The other 70% of the manganese is used purely as an alloying element. Steels usually contains anything from 0,2% to 2% manganese depending on grades as manganese is the cheapest alloying element among those which enhance some key mechanical properties such as strength and toughness.
Ferro-Manganese Ferro-Manganese is an alloy with high percentage of Manganese, which is made by heating a mixture of the oxides MnO2 and Fe2O3 and coal & coke with high carbon content in a blast furnace or an electric arc furnace-type system. The oxides go through carbothermal reduction in the furnaces that result in producing the Ferro-Manganese. Ferro-Manganese is used in the production of steel which acts as an excellent deoxidizer and desulfurizer. We supply the one variant of Ferro Manganese: High Carbon Ferro-Manganese.
