What is a saggar, how is it different from a crucible, and what is it used for? A saggar or a crucible are both ceramic containers used for high temperature applications. They can be made from very similar materials and their uses can also overlap. There are some typical differences in their shape, proportions, and […]

One of the most common questions we receive is why high-density ceramic components are often machined before they are fully fired. Once sintered, technical ceramics become extremely hard and more difficult to machine, so shaping the component in its unfired or ‘green’ state can significantly reduce machining time, tooling costs, and manufacturing complexity. Known as […]

A lot of people wonder how to choose the right saggar for a particular furnace application. The answer depends on several factors, including operating temperature, furnace atmosphere, the material being processed, and the heating method. Whether you are firing technical ceramics or managing complex metallurgical heat treatments, protecting your payload from atmospheric contamination and direct […]

Is a refractory or fully dense ceramic crucible the better choice? The most suitable choice is determined by how the crucible will be heated, the materials being processed, and the balance between thermal shock resistance and chemical resistance required for the application.  A core challenge engineers face is mitigating structural failure caused by rapid temperature […]

A question we hear a lot is: when is magnesium oxide a better choice than alumina? The answer depends on the materials being processed, the operating temperature, and the chemical environment inside the crucible. Choosing the right refractory ceramic material is critical to ensuring crucible longevity, maintaining material purity, and preventing premature crucible failure. In […]
