CN107352988A 一种超高强度陶瓷粉体 无效 - 驳回

一种超高强度陶瓷粉体
摘要：
本案公开了一种超高强度陶瓷粉体，包括50～52重量份的氧化硅、30～32重量份的氧化钙、24～26重量份的氧化锆、20～22重量份的氧化硼、5～7重量份的氮化硼、2～4重量份的氮化硅和氧化钕6～8重量份。本案通过对陶瓷粉体的改进优化，引入了多种具有协效作用的氧化物、氮化物和磷化物，有效提高了陶瓷的强度和抗冲击性能。通过在粉体中添加纳米级的碳酸锶，使得该陶瓷粉体在煅烧时，能通过碳酸锶分解出的细小二氧化碳气体，在陶瓷内部形成多个细小空腔，这些空腔联合形成类似蜂巢结构，进一步增强了陶瓷的强度、抗冲击性能和韧性。
摘要（英）：

The invention discloses ultrahigh-strength ceramic powder which comprises the following components in parts by weight: 50-52 parts of silicon oxide, 30-32 parts of calcium oxide, 24-26 parts of zirconium oxide, 20-22 parts of boron oxide, 5-7 parts of boron nitride, 2-4 parts of silicon nitride and 6-8 parts of neodymium oxide. By improving and optimizing the ceramic powder, multiple oxides, nitrides and phosphides with synergistic effects are introduced, thereby effectively enhancing the strength and impact resistance of the ceramic. By adding nano strontium carbonate into the powder, when the ceramic powder is calcined, a plurality of fine cavities can be formed inside the ceramic through fine carbon dioxide gas decomposed from the strontium carbonate; and the cavities are combined to form a honeycomb-like structure, thereby enhancing the strength, impact resistance and toughness of the ceramic.
