99% Alumina Ceramic Crucible with Lid RIWETRA 10mL 50×20×20mm

Description

Product Overview

The RIWETRA 99% alumina ceramic crucible is engineered for demanding high‑temperature applications where purity, durability, and precise dimensions are essential. Constructed from Al₂O₃ material with a purity exceeding 99%, the crucible offers exceptional resistance to thermal shock, chemical corrosion, and mechanical wear. Its compact square form measures 50×20×20 mm, providing a 10 mL internal volume that fits comfortably into standard laboratory furnaces, muffle ovens, and industrial heating chambers. The included lid is designed to seal tightly, preserving the internal atmosphere and preventing contamination during prolonged heating cycles.

Key specifications include a long‑term operating temperature of up to 1600 °C and a manufacturing temperature of 1800 °C, ensuring the crucible can endure the most rigorous thermal profiles without deformation. The product is supplied as a single piece with a matching lid, packaged securely to protect the ceramic surface during transit. This crucible is ideal for processes such as melt synthesis, alloy preparation, ceramic powder calcination, and high‑temperature analytical testing.

Usage

Designed for both laboratory research and industrial production, this crucible excels in environments where temperature control and material purity are critical. Researchers conducting material science experiments, such as phase diagram studies or high‑temperature spectroscopy, will benefit from the crucible’s stable thermal performance and low impurity levels. In industrial settings, the crucible is suitable for small‑batch metal melting, glass frit production, and specialty ceramic firing, where consistent results are paramount.

When using the crucible, it is important to follow recommended heating and cooling rates to avoid thermal shock. Below 1200 °C, temperature changes should not exceed 5 °C per minute, and above 1200 °C, the rate should be limited to 4 °C per minute. These guidelines help maintain the structural integrity of the alumina body and the lid’s seal. The crucible’s compact size also makes it easy to handle with standard tongs or robotic manipulators, facilitating automation in high‑throughput workflows.
