Graphite crucibles are widely used for melting non‑ferrous metals, mainly copper and aluminum alloys. Below is a brief introduction to the characteristics and applications of graphite crucibles.

Featuring rational designs, graphite furnaces have undergone continuous conceptual evolution and adopted new materials. Tests show that their energy consumption is lower than that of similar furnaces. Graphite furnaces serve a wide range of purposes and generate less polluting waste. They can run on clean energy fuels such as natural gas or liquefied petroleum gas, resulting in low pollution levels. Graphite crucibles for mobile furnaces are chiefly applied to melt gold, silver and rare metals, while ceramic crucibles are used for melting platinum, gold and rare metals.

Graphite crucibles have a low coefficient of thermal expansion and can resist deformation caused by heat and cold. They are also resistant to acids and alkalis, and are suitable for a broad range of fluid‑heating applications. For these reasons, graphite plates are extensively used and highly valued in the metallurgy, casting, machinery and chemical industries.

Beyond the aforementioned applications, graphite crucibles are also employed in vacuum furnaces. They greatly simplify the design and manufacturing of vacuum furnaces, cut the consumption of metals such as tungsten, molybdenum and stainless steel, reduce costs, and deliver high vacuum performance, thermal conductivity, safety and reliability.
