Novel silicon carbide porcelain boat

Abstract

The novel silicon carbide porcelain boat comprises a bottom surface and side walls surrounding the bottom surface, a cavity with an opening is defined by the bottom surface and the side walls, the side walls are two arc-shaped side walls which are oppositely arranged, end faces are arranged at the two ends of the two arc-shaped side walls respectively, and the end faces are arranged on the bottom surface. The two arc-shaped side walls, the two end faces and the bottom face jointly define the cavity. A porous silicon carbide top cover is arranged above the opening, the lower ends of the two side edges of the porous silicon carbide top cover are bent inwards to form clamping grooves, the upper edges of the two arc-shaped side walls are bent outwards to form clamping hooks, and the clamping grooves and the clamping hooks are matched to be used for connecting the porous silicon carbide top cover and the arc-shaped side walls; pressure relief millimeter holes are formed in the side edge of the porous silicon carbide top cover in the length direction at intervals. According to the invention, gas can enter and exit from the interior of the porcelain boat through the micron or nano pores, and solid samples in the porcelain boat cannot be dissipated out of the porcelain boat, so that the yield of products is improved.

Description

technical field [0001] The invention relates to the field of reaction vessel device design, in particular to a novel silicon carbide ceramic boat. Background technique [0002] Porcelain boat, also known as burning boat, is a vessel widely used in the field of chemical and chemical experiments. At present, the materials of the ceramic boats used in the market are mostly silica, alumina, aluminum titanate, etc. When in use, the reactant is placed in a porcelain boat, and then placed in a heating device such as an atmosphere tube furnace to conduct high-temperature sintering to synthesize nanomaterials. In the experiment, the uniform heating degree of the reactants affects the result of the reaction. It is a problem that needs to be solved to improve the thermal conductivity and thermal conductivity of the ceramic boat material. [0003] The above-mentioned common porcelain boats on the market are mostly designed without lids, and there are the following technical problems: ...

AI Technical Summary

Problems solved by technology

[0003] Most of the porcelain boats commonly used in the market are designed without a cover, and there are the following technical problems: in the circulating atmosphere, the samples in the porcelain boat are easy to scatter out of the porcelain boat with the airflow, polluting the tube furnace pipe and other adjacent porcelain boats. boat, also affects the yield of the reaction
