Understanding CAS 14808-60-7 A Comprehensive Overview
In the realm of chemical substances, the descriptor CAS refers to the Chemical Abstracts Service, which assigns unique numerical identifiers, known as CAS numbers, to chemical compounds. One such substance, identified by the CAS number 14808-60-7, is crystalline silica, a compound that warrants discussion due to its prevalence and importance in various industries.
What is Crystalline Silica?
Crystalline silica is a naturally occurring mineral composed primarily of silicon dioxide (SiO2). It is found in three main forms quartz, tridymite, and cristobalite. Among these, quartz is the most abundant and widely recognized form. Crystalline silica is a major constituent of many surface materials, including sand, soil, and rocks. Its durability and hardness make it a valuable resource in many industrial applications, including construction, mining, glass manufacturing, and ceramics.
The Role of Crystalline Silica in Industry
Crystalline silica plays a significant role in multiple sectors
1. Construction In the construction industry, silica sand is a key ingredient in concrete and mortar. Its properties contribute to the strength and durability of these materials, making it essential for building structures.

3. Foundry Applications Crystalline silica is extensively used in foundries for casting purposes. The fine sand aids in creating molds and cores, ensuring high precision and quality of metal castings.
4. Ceramics and Pottery In ceramics, silica is used to create fine china and porcelain. Its ability to withstand high temperatures and its aesthetic properties make it ideal for these products.
5. Oil and Gas Industry Silica sand is employed in hydraulic fracturing (fracking) processes to enhance oil and gas recovery. It propels fractures in rock formations, allowing for the extraction of fossil fuels.
Health and Environmental Concerns
While crystalline silica is invaluable for various industrial applications, it is also associated with significant health risks when inhaled as fine dust. Prolonged exposure to respirable crystalline silica can lead to serious health issues such as silicosis, lung cancer, and other respiratory diseases. Due to these risks, regulatory agencies, including the Occupational Safety and Health Administration (OSHA), have implemented stringent guidelines and permissible exposure limits to protect workers involved in industries where silica exposure is prevalent.
Employers are encouraged to adopt effective control measures, including proper ventilation, dust suppression techniques, and the use of personal protective equipment (PPE), to minimize exposure risks. Employee training on the hazards of crystalline silica and safe handling practices is also vital in promoting a safe working environment.
Regulatory Framework
The disposal and handling of crystalline silica are governed by various regulations globally. For instance, OSHA has established a permissible exposure limit for respirable crystalline silica in occupational settings. Additionally, the Environmental Protection Agency (EPA) monitors silica levels in air quality to protect public health and the environment.
Conclusion
CAS 14808-60-7, or crystalline silica, represents both an essential resource and a material that poses health risks in specific industry settings. Its wide-ranging applications underscore its importance in modern activities, yet caution is required to mitigate the health hazards associated with its inhalation. Understanding the properties, uses, and risks of crystalline silica is fundamental for anyone involved in sectors where this compound is prevalent. By adhering to safety regulations and employing best practices, we can harness the benefits of crystalline silica while safeguarding the health of workers and the environment.
