  • Résumé

  • Aware of how complex the problems related to the world of chemistry applied to ceramic production processes can be, we want to share our knowledge with those who want to orient themselves or train for passion or profession.
    Through a simple and direct language, the podcast aims to be an educational space with a focus on products, applications and processes.
    The journey unfolds along the ceramic production lines.
    At each stage a topic.
    At each topic a critical issue.
    At each critical issue, when possible, a solution.

  • Operating temperature & ceramic production

    Operating temperature & ceramic production
    Feb 17 2025
    The operating temperature is an important parameter that ceramic producers must take into account in order to avoid application problems that can also negatively affect the quality of the finished product.

    However, this parameter is not always easy to manage, especially if we consider the fluctuations promoted by seasonability.

    The episode addresses the topic with the help of specific examples, highlighting the main scenarios and the different levers on which one can act to better manage the anomalies that may occur along the production lines.

  • Chemicals for ceramic production: a focus on deflocculant and binders

    Chemicals for ceramic production: a focus on deflocculant and binders
    Feb 3 2025
    Most ceramic production processes involve the dispersion of ceramic powders in a liquid medium - mostly water - to obtain a suspension or, more generally, a dispersed system.

    To provde the suspensions with the desired stability and workability, depending on the different applications, we use the addition of small quantities of suitable chemicals that, interacting with the solid particles, change the rheological behaviour of the whole system.

    The episode offers a picture of two categories of chemical - deflocculants and binders - almost always involved in order to achieve the right result and therefore the correct application performance.

  • Analysis of ceramic suspensions: tools and purposes

    Analysis of ceramic suspensions: tools and purposes
    Jan 20 2025
    All analysis of ceramic suspensions carried out by those companies that supply chemicals for ceramic production are fundamental to properly develop the processes that take place along the production line.

    The episode provides an overview about the role of these important investigations, with a focus on the data and on the operations of the involved tools.

    We will talk about jars, pycnometers, laser granulometers, sieves, rheometers, pointing out how all these tools are important in providing ceramic producers with the correct information to proceed without problems or unexpected critical issues.
