In the realm of industrial chemistry, the precise properties of raw materials dictate the success of countless applications. Silicon dioxide, commonly known as silica, exists in various forms, each with distinct characteristics. Cristobalite (CAS 14464-46-1) is a specific crystalline polymorph of SiO2 that holds significant value due to its unique structural and chemical attributes. For procurement specialists and R&D chemists, understanding the nuances of this compound is key to optimizing formulations and processes. As a leading manufacturer of silicon dioxide, we provide detailed insights into why sourcing high-quality Cristobalite is crucial.

Chemical Identity and Purity of Cristobalite

Cristobalite, with the CAS number 14464-46-1, is chemically identified as silicon dioxide. Its molecular formula is O2Si, and its molecular weight is approximately 60.08. What distinguishes it from other forms of silica is its crystalline structure, which is stable at higher temperatures. The purity of industrial silica products can vary significantly, and for critical applications, high purity is paramount. Our Cristobalite is processed to achieve a minimum SiO2 assay of 99%, ensuring minimal contamination and predictable chemical behavior. This high purity is essential for applications where inertness and specific reactivity are required.

Key Chemical and Physical Properties

The typical properties of our supplied Cristobalite include a white to off-white granular appearance. Its high melting point (around 1713°C) and boiling point (>100°C, referring to its state rather than boiling) reflect its stability. The density is approximately 2.6 g/mL at 25°C. Chemically, it is insoluble in water and most acids, except for hydrofluoric acid, a characteristic common to many silica compounds. Its specific surface area and particle size distribution are carefully controlled to meet the demanding requirements of various industries, such as coatings, ceramics, and specialized fillers.

For chemical engineers and formulators, understanding these properties is vital. For example, the controlled particle size and surface area can influence rheology, dispersion, and mechanical strength in composite materials or coatings. When you buy silica granules from a reputable supplier in China, you can be confident in the material's consistent chemical composition and physical attributes.

Applications Driven by Chemical Properties

The chemical inertness and thermal stability of Cristobalite make it suitable for a wide array of industrial applications. As previously discussed, it excels in reflective paints, acting as a functional filler. It can also be found in advanced ceramics, refractories, and as a component in certain specialty chemicals where its physical form and chemical stability are beneficial. Research scientists often seek out specific silica polymorphs for their unique reactivity or inertness in catalytic processes or advanced material synthesis.
