Green granulation powder for aluminum oxide ceramic plunger and preparation method of green granulation powder
The green granulation powder is prepared from the following components in parts by weight: 60 to 95 parts of alpha aluminum oxide, 1 to 10 parts of silica powder, 1 to 9 parts of light calcium carbonate, 1 to 8 parts of kaolin, 1 to 8 parts of calcined talc, 1 to 5 parts of a coloring agent, 0.4 to 0.6 part of a dispersing agent, 4.5 to 7.5 parts of a binding agent and 1.2 to 2.5 parts of a release agent. The green granulation powder is moderate in water content, high in apparent density, high in green body density after blank pressing, not prone to edge breakage and corner falling and excellent in post-processing performance, the alumina ceramic plunger can have a microcrystal structure only through conventional dry pressing or isostatic pressing forming and firing processes, and the surface smoothness is high after grinding and polishing; in addition, the preparation method provided by the invention is simple in process and low in cost.
本申请提出一种适用于氧化铝陶瓷柱塞的绿色造粒粉，包括以下重量份的组分：α氧化铝60‑95份，硅微粉1‑10份，轻质碳酸钙1‑9份，高岭土1‑8份，煅烧滑石1‑8份，着色剂1‑5份，分散剂0.4‑0.6份，粘结剂4.5‑7.5份和脱模剂1.2‑2.5份。本申请中绿色造粒粉的含水量适中、松装密度高，压坯后生坯密度高、不容易崩边掉角、后加工性能出色，该绿色造粒粉只需经过常规干压或等静压成型和烧成工艺就能使氧化铝陶瓷柱塞具有微晶结构，经研磨抛光后表面光洁度高；此外本申请提出的制备方法工艺简单，成本低。
