Introduction to Zinc Oxide

Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors, and first-aid tapes.

Properties of Zinc Oxide

Properties of ZnO particles change depending on production conditions. The physical and chemical properties of ZnO are tuned by taking advantage of this. So the use of ZnO particles is attractive to many different industries.

The morphology of ZnO particles can vary greatly. ZnO particles produced through pyrometallurgical processes can have nodular or needle type shapes while Active ZnO particles produced through hydrometallurgical processes have porous structures.

The heat capacity and thermal conductivity of ZnO are very high while the thermal expansion coefficient of the material is relatively low. An important thermal property of ZnO is its thermochromism. Due to crystal lattice defects, the color of ZnO changes from white to yellow reversibly.

Zinc oxide is a well-known semiconductor. ZnO also shows piezoelectricity and pyroelectricity.

ZnO nanoparticles exhibit antibacterial properties. ZnO effects bacteria by either blocking their food source or disrupting their cell membranes.

Preparation Method of Zinc Oxide

ZnO nanomaterials are produced through physical, chemical or biological methods.

Physical methods include; physical vapor deposition, arc-plasma method, thermal evaporation, and ultrasonic irradiation. The thermal evaporation method is suitable for the production of ZnO nanotubes with photocatalytic properties.

This process is also simple, low cost and catalyst-free. Chemical production methods such as microemulsion, sol-gel, precipitation, chemical reduction, and chemical vapor deposition are also used for the production of ZnO nanostructures

Usage of Zinc Oxide

Sunscreen – Zinc oxide works as an excellent physical sunscreen, meaning it lays on our skin in a thin layer and reflects harmful UVA and UVB rays without absorbing into our skin. Thus, providing robust protection against the sun's harmful rays.

Calamine lotion – Zinc oxide works with other active ingredients to provide a barrier that helps dry skin that's weeping from poison ivy, poison oak, or poison sumac. It even has antimicrobial properties that can help keep germs at bay.

Astringent – Zinc oxide works as an astringent meaning it helps shrink skin and pores and can absorb excess oils. This can reduce acne and help keep our skin dry in the summer heat.

Breakfast cereal – Zinc oxide helps safely fortify breakfast cereals and other foods to make sure we're getting the nutrients we need.

Paint – Zinc oxide's white color and reflective properties make it a great pigment in many household paints.

Packaging and Storage

FAQ

Q: What are the benefits of using zinc oxide?

A: Zinc oxide is used as a bulking agent and a colorant. In over-the-counter drug products, it is used as a skin protectant and a sunscreen. Zinc oxide works as a sunscreen by reflecting and scattering UV radiation. Sunscreens reduce or prevent sunburn and premature aging of the skin.

Q: What are zinc oxide powder uses?

A: Common examples of zinc oxide powders include foot powders and makeup. As an ointment, it is also used in diaper rash products and sun protection products.

Q: What is the industrial application of zinc oxide?

A: ZnO along with stearic acid is used in the vulcanization of rubber to produce such things as tires, shoe soles, and even hockey pucks. A very important use is that Zinc Oxide is widely used as the buffer layer in CIGS (Copper Indium Gallium Selenide) solar cells.

Q: When not to use zinc oxide?

A: You should not use zinc oxide topical if you are allergic to zinc, dimethicone, lanolin, cod liver oil, petroleum jelly, parabens, mineral oil, or wax. Zinc oxide topical will not treat a bacterial or fungal infection.

Q: What is a characteristic of zinc oxide?

A: In its crystalline form, it is thermochromic which on heating in the presence of air changes its colour from white to yellow and on cooling it turns white in colour. It is an amphoteric oxide which is insoluble in water. It dissolves in acids and alkalis.

Q: Does zinc oxide protect from sun?

A: Zinc oxide is well known for protecting against a wide spectrum of UV. However, mineral combinations, including TiO2, are widely used because it is easier to achieve a higher SPF (TiO2 primarily absorbs in the UVB range).

Q: Why have people avoided using zinc oxide in the past?

A: If you inhale a significant quantity of zinc oxide, more than you would encounter in daily life, you can become ill.

Q: Is zinc oxide anti-fungal?

A: Nanoparticles of zinc oxide have been found to have antimicrobial activity (antifungal and antibacterial properties). As a result, zinc oxide sunscreens (physical sunscreens) are a particularly good choice for people with redness, rosacea, and sensitive skin.

Q: What are the special properties of zinc oxide?

A: ZnO is a relatively soft material with approximate hardness of 4.5 on the Mohs scale. Its elastic constants are smaller than those of relevant III-V semiconductors. The high heat capacity and heat conductivity, low thermal expansion and high melting temperature of ZnO are beneficial for ceramics.
