The price of nickel and stainless steel rose together. Nickel afternoon hand in hand with stainless steel together turn red up. Due to the temporary easing of geopolitical risks, risk assets are now picking up, nonferrous metals, stock markets, and so on have risen, the overall mood has temporarily improved. Ore prices are strong, the overlay of the epidemic on spot logistics or the formation of a certain impact. Phase, nickel and stainless steel materials to maintain high wide concussion pattern.
Nickel prices based on low inventory, tight supply and demand will still show high wide fluctuations. In addition, the current LME has low liquidity, so its sensitivity to capital will remain relatively high. Shanghai nickel-wide fluctuations are expected to continue in the 200,000-250,000 yuan wide repeated fluctuation trend. While stainless steel is affected by the stronger nickel pig iron, the cost support continues, but note that under the current demand is not effectively released, the upward space may also be affected, the stage is expected to fluctuate between 20000 and 22,000 yuan. The price of nickel produced such fluctuations, indicating that the price of the ZnS powder may also be affected to a certain extent.
What is Zinc Sulfide ZnS Powder?
Zinc sulfide is an inorganic compound with the chemical formula ZnS. Zinc sulfide is a white to pale or light-yellow powder. When exposed to light it becomes darker. Stable in dry air, it gradually oxidizes to zinc sulfate in wet air or when it contains moisture. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water.
Zinc Sulfide ZnS Structure
ZnS exist in two main crystal types, and this duality is usually a prominent example of the polycrystalline type. In each form, the coordination geometry of Zn and S is tetrahedral. The more stable cubic form is also called sphalerite. The hexagonal form is known as the mineral wurtzite, although it can also be produced synthetically. The transition from sphalerite to wurtzite occurs at about 1020°C. The tetragonal form is also known as a very rare mineral, called lithium manganese ore, with the formula (Zn, Hg) S.
What is Zinc Sulfide ZnS Used For?
Zinc sulfide is mainly used in paint and plastics in chemical production. Because of its white opacity and insoluble in water, organic solvents, weak acid, weak base and become an important pigment in paint. Zinc sulfide is now the second most important pigment in the United States after titanium dioxide but continues to play an important role in European industry.
As a bulk material, the melting point of zinc sulfide is 1650℃, the Mohs hardness of 98% commercial-grade zinc sulfide is 3.0, and the refractive index is 2.37. Because of its high refractive coefficient and wear resistance, zinc sulfide pigment in equipment, wax paper, and metal plate coated with a very thin layer has relatively high hiding power.
Zinc sulfide is easy to disperse and not easy to agglomerate. It is neutral white and has good optical properties. It is often used as a component of thermosetting plastics, thermoplastic plastics, reinforced fiberglass, flame retardant, artificial rubber, and dispersant.
Zinc sulfide, added with a few PPM of suitable activator, exhibits strong phosphorescence (described by Nikola Tesla in 1893) and is currently used in many applications, from cathode ray tubes to X-ray screens to products that glow in the dark. When silver is used as an activator, the resulting color is bright blue, with a maximum size of 450 nanometers. The use of manganese produces an orange-red color of about 590 nanometers. Copper glows for a long time, and it has a familiar green glow. Copper-doped zinc sulfide (" ZnS plus Cu ") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities exposed to blue or ultraviolet light.
Zinc sulfide is also used as an infrared optical material, transmitting from visible wavelengths to just over 12 microns. It can be used flat as an optical window or molded as a lens. It is made by synthesizing hydrogen sulfide gas and zinc vapor on a microchip and is sold in FLIR grade (forward-looking infrared), where zinc sulfide is in a milky yellow, opaque form. This material can be converted to a transparent form called Cleartran (trademark) under hot isostatic pressure (HIPed). The early commercial form was marketed as IRTRAN-2 but this name is now obsolete.
Zinc sulfide is a common pigment sometimes called Sachtolith. Zinc sulfide forms lithopone when combined with barium sulfate.
Fine ZnS powder is a highly efficient photocatalyst that produces hydrogen gas from water under the light. Sulfur vacancies are introduced in the synthesis of zinc sulfide. This gradually turns the white-yellow ZnS into a brown powder and improves the photocatalytic activity by enhancing light absorption.
Both sphalerite and wurtzite are inherently wide band-gap semiconductors. These are typical II-VI semiconductors that use structures related to many other semiconductors, such as gallium arsenide. The band gap of the cubic form of ZnS is about 3.54 EV at 300 Kelvin, but the band gap of the hexagonal form is about 3.91 EV. ZnS can be doped as n-type or P-type semiconductors.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the ZnS powder will be influenced by that.
