Overview
Titanium hydroxide (Ti(OH)4) is an inorganic compound primarily used as an intermediate in the synthesis of titanium dioxide (TiO2), a widely used white pigment. It is also employed in the production of ceramics, catalysts, and specialty coatings. The compound is typically obtained through the hydrolysis of titanium salts, such as titanium tetrachloride (TiCl4), under controlled conditions. Due to its high reactivity, titanium hydroxide is rarely isolated in its pure form for extended periods. Instead, it is often processed immediately into more stable titanium compounds. Its role as a precursor makes it a critical material in industries ranging from paints and plastics to electronics and environmental engineering.
Physical and Chemical Properties
Titanium hydroxide appears as a white, amorphous powder with a density of approximately 3.9 g/cm³. It is insoluble in water but readily dissolves in acidic solutions, forming titanium salts. The compound is thermally unstable and decomposes upon heating, typically yielding titanium dioxide and water. Its high reactivity with acids makes it useful in chemical synthesis, while its insolubility in water necessitates careful handling to avoid unwanted reactions. The molecular weight of Ti(OH)4 is 115.90 g/mol, and its CAS number is 20338-08-3. These properties are critical for industrial applications where precise control over material characteristics is required.
Main Applications
The primary use of titanium hydroxide is as a precursor in the production of titanium dioxide (TiO2), which is a key component in paints, coatings, and plastics. TiO2's high refractive index and opacity make it ideal for providing whiteness and brightness to products. Beyond pigments, titanium hydroxide is used in the manufacture of ceramics, where it contributes to the material's strength and durability. It also serves as a catalyst support in chemical reactions and is explored for environmental applications, such as water purification and photocatalysis. Its versatility makes it valuable across multiple industries.
Safety and Storage
Titanium hydroxide requires careful handling due to its reactivity with acids and moisture. It should be stored in a cool, dry environment, preferably in airtight containers to prevent degradation. Direct contact with skin or inhalation of dust should be avoided, as it may cause irritation. Personal protective equipment (PPE), such as gloves and masks, is recommended when handling the compound. In case of exposure, rinse affected areas with water and seek medical advice if necessary. Proper storage and handling protocols are essential to maintain the material's integrity and ensure workplace safety.
B2B Procurement Guide
When procuring titanium hydroxide, B2B buyers should prioritize suppliers that provide detailed specifications, including purity levels and moisture content. Bulk purchases often come with cost advantages, but quality consistency must be verified through certificates of analysis (CoA). It is advisable to establish long-term relationships with reputable manufacturers to ensure a stable supply chain. Buyers should also consider logistical factors, such as packaging and transportation conditions, to prevent contamination or degradation. Competitive pricing can be found by comparing quotes from multiple suppliers, but quality should not be compromised for cost savings.
