RWZ microwave high temperature top-hat kiln


(1) introducttion

RWZ microwave high temperature top-hat kiln is mainly used in the firing for mass production under protective or weak reducing atmosphere. It can be vacuumed and passing through protective or weak reducing atmosphere. Due to the microwave catalytic and non-thermal effects, it is helpful for solid phase diffusion of samples, and final sample’s densification and mechanical properties is better than conventional sintered sample. In comparison to the traditional heating equipment, our kiln’s structure is simpler, larger in capacity, smaller foot-print, higher efficiency and quality. It also can save energy over 60%.
