Bottom semi-circular sapphire boat (ceramic ark)

This product is a bottom semi-circular sapphire boat, also referred to as a ceramic ark, designed for high-temperature sintering and material processing applications in research laboratories. Manufactured by Canrd under model MA-CM-SI-0008, it offers a selection of seven dimension options, ranging from 250×40×18 mm to 60×54×24 mm, with some variants including a fitted cover for controlled atmosphere or containment during thermal treatment. The sapphire construction provides excellent thermal stability, chemical inertness, and resistance to thermal shock, making it suitable for handling reactive or high-purity materials in processes such as crystal growth, powder calcination, or thin-film deposition. Its semi-circular cross-section facilitates uniform heat distribution and easy sample retrieval. These boats serve as reliable consumables for experimental setups in advanced materials, battery research, and ceramic synthesis, where consistent performance and contamination-free operation are essential.
