Anti-static black aluminum oxide ceramic substrate and preparation process thereof
The invention relates to an anti-static black aluminum oxide ceramic substrate and a preparation process thereof. The ceramic substrate comprises ceramic powder, an organic solvent, a dispersing agent, a binder and a plasticizer. The black aluminum oxide ceramic substrate is prepared through the processes of tape casting, warm pressing and sintering. The ceramic powder comprises the following materials in parts by weight: 40-55 parts of aluminum oxide, 2.5-5 parts of nano semiconductor whiskers, 5-20 parts of special anti-static black pigment, 20-30 parts of an organic solvent, 1-3 parts of a dispersing agent, 5-8 parts of an adhesive and 3-7 parts of a plasticizer. The special anti-static black pigment can form a continuous conductive phase, and static accumulation is reduced. The added nano semiconductor whiskers have certain conductivity, and the whiskers form a conductive and heat-conducting network channel in the substrate through a warm-pressing process, so that generated electrostatic charges can be discharged in time, and meanwhile, the heat dissipation performance of the substrate is further enhanced. The light-shielding and light-absorbing material has good light-shielding and light-absorbing performance, and is suitable for photosensitive integrated circuits, semiconductor components, nixie tube packaging shells and the like. The problem that electronic components are damaged due to static electricity accumulation generated in the manufacturing and using processes of the electronic devices is effectively solved.
本发明涉及一种防静电黑色氧化铝陶瓷基板及其制备工艺。所述陶瓷基板组成包括陶瓷粉体、有机溶剂、分散剂、粘结剂和增塑剂。通过流延、温压、烧结工艺制备得到黑色氧化铝陶瓷基板。陶瓷粉体包括以下重量份材料：40‑55份氧化铝，2.5‑5份纳米半导体晶须，5‑20份特制防静电黑色色料，20‑30份有机溶剂，1‑3份分散剂，5‑8份粘接剂，3‑7份增塑剂。特制防静电黑色色料能够形成连续导电相，减少静电积累。其中加入的纳米半导体晶须具备一定的导电性能，晶须通过温压工艺在基板内部形成导电、导热网络通道，能够及时地将产生的静电电荷排出，同时也进一步增强了基板的散热性能。本发明具有良好的遮光吸光性能，适用于光敏性集成电路、半导体元器件和数码管封装外壳等。有效解决了电子器件在制造和使用过程中产生静电积累，造成电子元器件损害的问题。
