LABORATORY CERAMICS

STILLMEL LLC is a leading manufacturer of high-refractory, high-strength, and wear-resistant alumina (corundum) ceramics.

Our products are manufactured from high-purity, fine-dispersed aluminum oxide powders using modern technological equipment, controlled forming methods, and firing regimes.
The operating temperature of the ceramics is up to 1800 °C.

The company continuously expands its product range and implements new technical solutions in accordance with industrial and laboratory process requirements.

Alumina ceramics are characterized by:
- high refractoriness (up to 1800 °C);
- mechanical strength and wear resistance;
- high density and hermeticity (vacuum tightness);
- chemical resistance to aggressive environments (acids and alkalis);
- dimensional stability under thermal loads;
- low thermal conductivity and good insulating properties.

These characteristics ensure reliable performance under severe thermal and chemical operating conditions.

Fields of Application.
Melting of ferrous and non-ferrous metals, high-temperature glass, glazes, and enamels.
Laboratory ceramics in the form of crucibles, boats, and containers are widely used in melting processes of aluminum, copper, nickel, their alloys, and other metals.
The products withstand temperatures exceeding 1800 °C without deformation, do not react with melts, and prevent contamination of metals by foreign impurities.
This is particularly important for the jewelry industry, electronics, and precision casting.

High-temperature glass production.
Ceramic components are used in optical, energy, and specialized chemical processes.

Laboratory applications.
Such products are used for high-temperature synthesis, thermal treatment of samples, analytical research, and operation with aggressive reagents.
The chemical inertness of the material eliminates interaction with reagents and ensures high accuracy in spectroscopic, chromatographic, and other analytical methods.

Electrical and thermal insulation.
Engineering ceramics in the form of tubes, sleeves, rings, rods, relay housings, various nozzles, injectors, and other components are used to protect heating elements in furnaces and support various functional production processes.
High density, hermeticity, and favorable physical properties enable widespread use in scientific and technical applications.

Grinding and mixing of superhard materials.
Structural ceramics in the form of various geometric bodies-balls, cylinders, pyramids, pestles, mortars, etc.-are used for efficient grinding and ensuring material homogeneity in production processes.
The hardness and wear resistance of corundum ceramics determine their applicability across multiple industrial sectors.
