Cooking utensil and preparation method thereof
The invention relates to a cooking utensil and a preparation method thereof. The cooking utensil comprises a cooking container provided with a cooking cavity, the cooking container comprises a porous ceramic matrix, a glaze layer and a carbon film, the glaze layer is attached to the inner surface and the outer side wall of the porous ceramic matrix, and the absolute value of the difference value of the thermal expansion coefficient of the glaze layer and the thermal expansion coefficient of the porous ceramic matrix is smaller than or equal to 3 * 10 <-6 >/DEG C; the carbon film is attached to the bottom of the outer surface of the porous ceramic matrix and permeates inwards to form a carbon-containing area, the thickness of the porous ceramic matrix is taken as H, in the carbon-containing area, the carbon content of the outer surface of the porous ceramic matrix is larger than or equal to 10 wt%, the carbon content at the H/2 position is larger than or equal to 3 wt%, and the carbon content of the carbon-containing area is gradually decreased from the outer surface of the porous ceramic matrix to the direction close to the inner surface. The cooking utensil has excellent heat conduction performance, cold and hot impact resistance and heat preservation and heat storage performance.
本发明涉及一种烹饪器皿及其制备方法。所述烹饪器皿包括设置有烹饪腔的烹饪容器，烹饪容器包括多孔陶瓷基体、釉层和碳薄膜，其中，釉层附着于多孔陶瓷基体内表面和外侧壁，釉层的热膨胀系数与多孔陶瓷基体的热膨胀系数差值的绝对值≤3×10‑6/℃；碳薄膜附着于多孔陶瓷基体外表面的底部且向内渗入形成含碳区，将多孔陶瓷基体的厚度计为H，在含碳区中，多孔陶瓷基体外表面的碳含量≥10wt％，H/2处碳含量≥3wt％，且含碳区的碳含量由多孔陶瓷基体外表面至靠近内表面的方向递减。所述烹饪器皿具有优异的导热性能、耐冷热冲击性能及保温蓄热性能。
