摘要： PROBLEM TO BE SOLVED: To provide ceramic granules with high fluidity, a high-denseness ceramic sintered compact produced by using the ceramic granules, and a protective member.SOLUTION: The ceramic granules principally consist of silicon carbide or boron carbide and include a sintering aid, carbon sources including lignin sulfonate and lignin carboxylate, and a forming aid. Since the lignin sulfonate and lignin carboxylate are included as the carbon sources, the ceramic granules hardly absorb moisture in the air and are prevented from reduction in their fluidity, and a molded product with high density can be obtained. The ceramic granules hardly absorbing moisture in the air can prevent corrosion of a die used during molding, and consequently, risk of contamination by impurities occurring from corroded metal can be reduced.
摘要翻译：要解决的问题：提供高流动性的陶瓷颗粒，通过使用陶瓷颗粒制成的高密度陶瓷烧结体和保护构件。溶液：陶瓷颗粒主要由碳化硅或碳化硼组成，并且包括烧结助剂，包括木质素磺酸盐和木质素羧酸盐的碳源和成型助剂。由于含有木质素磺酸盐和木质素羧酸盐作为碳源，陶瓷颗粒几乎不吸收空气中的水分，并且防止其流动性降低，并且可以获得高密度的模塑产品。几乎不吸收空气中的水分的陶瓷颗粒可以防止在模制期间使用的模具的腐蚀，因此可以降低由腐蚀的金属产生的杂质污染的风险。

摘要： PROBLEM TO BE SOLVED: To provide a porous material comprising a carbon nanofiber aggregate in which the adhesion among carbon nanofibers is satisfactory and having a low bulk density, and to provide its production method. SOLUTION: The porous composite is one that comprises a network-forming inorganic fiber aggregate in which the inorganic fibers are bound together through a ceramic substance, wherein the inorganic fibers are carbon nanofibers, and the ceramic substance is a carbide-type ceramic substance. For example, the composite material is produced by impregnating a molding comprising an aggregate of carbon nanofibers with a solution of a polymeric precursor convertible into a carbide-type ceramic, removing the solvent of the solution from the impregnated molding, and firing the solvent-freed molding.
