À propos de cet audio

 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.Zschimmer & Schwarz Ceramco Chimie Science Éducation

  • On black cores and degassing: analyzing a defect

    On black cores and degassing: analyzing a defect
    Dec 4 2025
    This episode provides a quick overview of the “black core” effect—an internal discoloration in porcelain tiles, typically caused by incomplete oxidation of the ceramic body due to trapped organic residues.

    It highlights the production conditions that make the defect more likely to appear and then outlines practical corrective strategies to prevent it.

    All in just ten minutes.

  • Bubbles, surfactants, and defoamers

    Bubbles, surfactants, and defoamers
    Nov 10 2025
    In ceramic manufacturing, aqueous suspensions play a crucial role in shaping processes and determining the final quality of products.

    However, foam formation can disrupt production, leading to defects and lower efficiency.

    This episode dives into the world of foaming phenomena, exploring how they arise and how they affect the properties of suspensions.

    We discuss surfactants, which can encourage foam formation, and defoamers, which help keep it under control.

    What key insights are needed to effectively manage these challenges?
