Zirconia porous (ZR-95-VG)
95% ZrO2
In laboratory use, particularly when melting precious metals, proper handling is essential to ensure the longevity of zirconia crucibles. We recommend using porous zirconia crucibles in combination with high-grade alumina crucibles (quality KR-98-VG), embedding them carefully with a suitable investment compound. This approach protects the more sensitive porous structure from mechanical stress while ensuring uniform temperature distribution. The result: significantly longer service life and improved process reliability.
With decades of experience in the development and production of technical ceramics, GTS Keramik is your reliable partner for components made of porous zirconia. Whether crucibles, tubes, plates, or custom parts – we offer both standard products and tailored solutions according to your specifications. From material selection and design consultation to manufacturing, we support you with speed, competence, and quality. Rely on high-performance ceramic solutions “Made in Germany” when durability, precision, and reliability matter. GTS Keramik – High-Performance Ceramics with Responsibility and Passion.
