Nitride ceramic sintering method
The invention relates to a nitride ceramic sintering method. The sintering method comprises the following steps that a nitride green body and specific inorganic matter powder are independently placed in the same boron nitride sagger, and then the boron nitride sagger is placed in a graphite furnace to be sintered. According to the sintering method, the problems of redness and blackening in the sintering process of the aluminum nitride ceramic can be effectively solved, and the aluminum nitride ceramic obtained after sintering is uniform and consistent in color and free of the redness or blackening phenomenon.
本发明涉及一种氮化物陶瓷烧结方法。该烧结方法包括如下步骤：将氮化物生坯体和特定的无机物粉末独立地置于同一氮化硼匣钵中，然后将氮化硼匣钵置于石墨炉，烧结。该烧结方法可以有效地改善氮化铝陶瓷烧结过程中的发红和发黑的问题，烧结后得到的氮化铝陶瓷颜色均匀一致，无发红或发黑现象。
