Overview
Titanium dioxide tablets are a compressed form of titanium dioxide (TiO2), a naturally occurring oxide of titanium. They are widely recognized for their high opacity, UV resistance, and chemical stability, making them a preferred choice in various industries. The tablet form ensures ease of handling and precise dosing, which is particularly beneficial in pharmaceutical and cosmetic applications. TiO2 tablets are manufactured through a compression process that ensures uniform density and consistency. This form factor is especially useful in applications where powdered TiO2 might pose handling challenges, such as in cleanroom environments or automated production lines.
Physical and Chemical Properties
Titanium dioxide tablets exhibit a high refractive index, which contributes to their exceptional opacity and brightness. They are chemically inert under normal conditions, resisting reactions with most acids, bases, and organic solvents. This inertness makes them suitable for use in sensitive applications like pharmaceuticals and food additives. The tablets are thermally stable, with a melting point of 1843°C and a boiling point of 2972°C. Their insolubility in water ensures longevity in aqueous formulations, while their slight solubility in strong acids allows for controlled release in specific industrial processes. The density of TiO2 tablets is approximately 4.23 g/cm³, providing a compact and efficient form for storage and transportation.
Main Applications
In the pharmaceutical industry, titanium dioxide tablets are commonly used as excipients to provide opacity and protect active ingredients from light degradation. They are also used in tablet coatings to improve appearance and swallowability. In cosmetics, TiO2 tablets serve as a key component in sunscreens, foundations, and other products requiring UV protection and opacity. The food industry utilizes TiO2 tablets as a whitening agent in products like candies, chewing gum, and dairy products. Additionally, they are employed in industrial coatings and plastics to enhance durability and aesthetic appeal. Their versatility and safety profile make them a staple in multiple sectors.
Safety and Storage
While titanium dioxide is generally considered safe, prolonged exposure to dust particles can pose respiratory risks. It is essential to use appropriate personal protective equipment (PPE), such as masks and gloves, when handling TiO2 tablets in powder form. Proper ventilation is also recommended to minimize airborne particles. Storage conditions should prioritize cool, dry environments to prevent moisture absorption, which can compromise the tablet's integrity. Containers should be tightly sealed and labeled according to regulatory requirements. Compliance with local safety guidelines ensures safe handling and disposal.
B2B Procurement Guide
When procuring titanium dioxide tablets, B2B buyers should prioritize suppliers who provide detailed purity certifications and comply with industry standards such as USP, EP, or FDA guidelines. Bulk purchases often attract discounts, but it's crucial to balance cost with quality to avoid substandard products. Consider the specific application requirements, such as particle size and purity levels, when selecting a supplier. Establishing long-term partnerships with reliable manufacturers can ensure consistent quality and timely delivery. Additionally, inquire about customization options, such as tablet size or additives, to meet unique production needs.
