Prepare your enquiry
What does your crucible need to withstand?
Whether you have an existing crucible, a technical drawing or a new application, tell us what you need using the information you already have.
Discuss custom dimensions
Send a drawing or sketch showing the shape, dimensions and wall thicknesses. GTS will assess the options for your required design.
Send a drawing →Describe your application
Describe the sample or material to be melted, your furnace and the process conditions so that we can discuss the technical requirements.

Applications in laboratories and industry
For samples, melting trials and thermal processes
In laboratories, ceramic crucibles are used for sample preparation, materials analysis, heat treatment and materials development. Industrial applications include metallurgy, foundries, and the glass, ceramics and chemical industries. The appropriate design depends on the process.

Materials and operating conditions
Which ceramic suits your process?
Temperature limits and chemical resistance depend on the material grade and operating conditions. Atmosphere, geometry and the temperature profile are equally important. Repeated thermal cycles also require consideration of heating and cooling rates.

Frequently asked questions
Before you get in touch
Key answers to help you prepare a technical enquiry.
What temperatures can ceramic crucibles withstand?
This depends on the ceramic material, geometry and operating conditions. The technical data for the specific material grade and the requirements of your process are the deciding factors.
Which ceramic is suitable for my application?
Temperature, atmosphere, the material to be melted or sample, and the chemical and thermal loads are key to discussing the technical requirements. GTS provides material information and helps you define the design. Suitability must be verified in the specific process.
Are ceramic crucibles suitable for repeated thermal cycles?
They may be, depending on the material and process. Heating and cooling rates, thermal loads and geometry are among the key factors. The design must match these conditions.
Can custom dimensions be manufactured?
Custom dimensions, shapes and wall thicknesses can be assessed for feasibility, depending on the material and manufacturing process. Please specify the required geometry and quantity.
Can I send technical drawings?
Yes. For custom enquiries, you can send drawings, sketches, photographs and technical requirements. Please also include the temperature, atmosphere and material to be melted where possible.
