Supports high-density and sintering of ceramics in a high-temperature firing of up to 3000℃ and low-oxygen atmosphere.

In the densification of ceramic materials, it is necessary to examine the optimal heat treatment conditions for each material, including debinding, pre-sintering, sintering, pressure sintering, and atmosphere control. In particular, when high-temperature processing is desired while suppressing oxidation, or when the temperature, atmosphere, and furnace dimensions of a conventional electric furnace do not meet requirements, the use of a carbon furnace is effective. Our carbon furnace supports high-temperature heating up to 3000°C and enables firing in a low-oxygen atmosphere by replacing the environment with inert gases such as Ar or N2 after vacuum pumping. Custom designs tailored to specific purposes are possible, ranging from research and development to mass production equipment, for applications such as densification of ceramics, promotion of sintering, phase formation, and high-temperature processing after debinding. We can address challenges such as the following: ■ I want to increase the density of ceramics. ■ I want to consider high sintering temperatures. ■ I want to consistently perform firing and densification after debinding. ■ I want to fire while suppressing oxidation and compositional changes. ■ I want to process in atmospheres such as Ar, N2, or vacuum. ■ The dimensions and temperature conditions of off-the-shelf furnaces do not meet my needs. ■ I want to consult from lab testing to mass production furnaces.
