Zinc oxide: useful properties of the substance
Zinc oxide (also commercially available under the name zinc oxide) is a crystalline powder without a characteristic color and odor that does not dissolve in water. Its white crystals turn yellow when heated. This type of inorganic compound has an intense astringent, drying and antiseptic effect. It is thanks to these beneficial properties that the substance has found wide application in a wide variety of industries, both in industry and in everyday life. Its spectrum of applications ranges from cosmetology and the treatment of skin problems at home to electronics and the oil industry - which is why it is worth ordering zinc oxide right now.
How zinc oxide is obtained
At the moment, this substance is synthesized in a variety of ways. Under natural conditions, it is part of the earth's crust in the form of the mineral zincite. But for the comprehensive satisfaction of commercial demand for zinc oxide, it is not required to extract it from the bowels of the earth, but to obtain the required amount of a chemical by industrial means.
There are several main ways to obtain zinc oxide, namely:
• combustion of Zn vapors in an oxygen atmosphere;
• decomposition during heating of some chemical compounds based on this component;
• roasting zinc sulphide in an environment conducive to its intense oxidation;
• oxide is synthesized at high steam pressure;
• when the spar is heated to a high temperature;
• it is obtained from various types of waste from the metallurgical industry;
• as a result of the withdrawal of zinc oxide from the ternary system.
Zinc oxide: the main characteristics of the substance
The formula of this inorganic compound is ZnO, it is constantly in a solid state and does not have a characteristic odor. If we talk about its ability to dissolve in different media, then this process is impossible in water. This substance is poorly soluble in alcohol, but in alkaline solutions this process goes much better.
This type of chemical is classified as a direct gap semiconductor. In the process of natural creation of metal alloys using oxygen, zinc oxide is transformed into another type of semiconductor.
It is also worth noting other properties of zinc powder, namely:
• its sublimation takes place at 1800 degrees;
• the substance melts at 1975 degrees;
• its thermal conductivity is 54 W / (m * K);
• when interacting with acids, zinc oxide forms salts, and with alkalis - complexes;
• in the process of dissolving zinc oxide in an aqueous solution of ammonia, amino complexes are formed;
• interaction of the substance with alkalis and metal oxides forms zincates;
• the reaction of interaction with oxides of Si and B leads to the formation of borates and silicates.
Zinc oxide: what is it for
This substance is in demand in various fields because it is multifunctional. For example, even the manufacture of eco-leather, gas masks, electric cables is not complete without its use. But this is far from all the areas in which its use is required.
Zinc oxides have also found a worthy application in dentistry. On the basis of this chemical component, cements for filling and tooth cleaning pastes with an abrasive effect are made.
Zinc oxide is actively used in the production of rubber tires, at enterprises of the oil refining and paint industry. It is on the basis of this substance that glasses and paints, as well as ceramics, are produced. In the ceramics industry, zinc oxide is highly valued for its ability to lower the melting point of the glaze and improve the elasticity of the ant.
In the chemical industry, the range of use of the substance is extremely wide. It is used for:
• production of chloroprene rubbers - zinc oxide is required for vulcanization of rubber;
• synthesis of methyl alcohol - zinc oxide acts in this process as a catalyst for the reaction;
• making enamels and paints - here zinc oxide is needed as a white pigment;
• production of perfumes, toilet waters, cosmetics and various types of paper products - zinc oxide is used as a pigment and filler;
• manufacture of animal feed;
• removal of deep rust.
We will also separately consider the use of zinc oxide in the field of electronics. On its basis, varistors are made, which are required for the production of surge arresters. It is also used to create electrical cables and ferrites. Zinc powder is also essential for the proper functioning of powder lasers. Zinc oxide is actively involved in the manufacture of blue LEDs, it is a part of heat-conducting pastes.
The nanostructures of this substance, its thin films are used to obtain gas or biosensors with high sensitivity. In a heated state, zinc oxide is capable of absorbing various types of gases, but at the same time the degree of its conductivity changes.
We recommend buying zinc oxide due to the increased interest of industrial industries in the properties of its thin-film layers. It is precisely the successful combination of electrophysical and optical properties is most useful for the application of zinc oxide for industrial purposes. The thing is that zinc oxide films are extremely resistant to the effects of the atmosphere, and also have a sufficient level of chemical inertness.
Zinc Oxide Powder: Uses for Treatment
This amphoteric oxide is most often used in medicine and pharmacy, as it has a beneficial effect on the human body. The positive effect of zinc oxide is especially noticeable on the skin. The fact is that the main principle of action of zinc oxide is the ability to denature proteins and form albuminates. If the substance is applied to damaged areas of the skin, then after a short amount of time the phenomena of exudation on its surface will become much less, like irritation and inflammation.
Also, the important properties of zinc oxide include:
• intense astringent effect;
• the ability to effectively dry the skin;
• enhancing the production of collagen by skin cells;
• reducing the harmful effects of environmental factors on the skin.
Zinc oxide is highly valued by dermatologists, therefore it is the main component of medicines for sunburn, dermatitis, dry and weeping eczema, ulcers, bedsores, streptoderma, scratches, diaper rash in adults and children. Zinc-based products are approved for use even on the sensitive skin of newborns, since this substance does not penetrate deep into the skin and does not accumulate in it.
Zinc oxide is not so rare in cosmetics. It is also used in sunscreens as a UV filter. Due to its biological and chemical inertness, as well as non-toxicity, zinc oxide is actively used in the manufacture of hypoallergenic cosmetics for adults and children and cosmetics for sensitive skin.
