氧化铝

These experiments use a raw material-pseudo boehmite gel from Wenzhou JingJing Aluminum Oxide Co.

本论文实验使用同一种物料-温州精晶氧化铝有限公司生产的拟薄水软铝石水凝胶。

But during dry process the surface pores of boehmite gel will first close, and the water in boehmite gel can't burn out so that it occurs cracks in green body.

唯这种制程仍存在下列问题：(1)氧化铝与boehmite胶体的混合泥料仍然太湿，要去除过多水分才能适用於挤出成形。

Firstly, A mixing solvent composed of benzene and isopropanol was used to prepare boehmite sols in the Sol-Gel processes during the preparation of asymmetric alumina membranes taking aluminum isoproxide as raw materials. And the operation conditions in relative periods were optimized.

首先，在以异丙醇铝为原料采用Sol-Gel法制备不对称氧化铝膜的过程中，提出用溶解度较大的苯与异丙醇组成的混合溶剂作为分散剂来配制Boehmite溶胶，并且对各环节的控制条件进行了优化。

Alumina ceramic was formed after gelling and solidify using boehmite as a binder.

探讨了利用拟薄水铝石作为粘结剂，胶凝固化后成型氧化铝陶瓷。

In comparison with the conventional method of coating on the tool surface, carbide powders were coated with boehmite sol when dispersed in the mixture of boehmite sol and ethanol. The coated powders were then dried, separated, and hot-pressed. The sol preparation techniques were optimized in experiments and the property of the sol was studied at the same time.

本文从提高硬质合金刀具的耐磨性、探索新型刀具涂层方法入手，突破了在刀具表面进行涂层的传统方法，提出了用溶胶－凝胶法在硬质合金碳化物粉末表面涂覆一薄层氧化铝陶瓷制成复合粉末，然后热压制备刀具材料的新方法，开发成功一类新型的陶瓷涂层硬质合金复合刀具材料。

Asked if NALCO plans to cut alumina production and increase aluminium production, company chairman C.R.

当问及是否国家铝业公司计划减少氧化铝产量而提高铝产量时，总裁C.R。

The flame retardant asphalts were prepared with Liaohe AH-70 type high-quality paving asphalt as feedstock,decabromo-diphenyl oxide,decabromo-diphenyl ethane,antimonous oxide et al as flame retardants,aluminum hydroxide as smoke inhibitor and drawing off oil high in aromatics as dispersion medium under the condition of heating and mixing.

以辽河AH-70高等级道路沥青为原料，十溴联苯醚、十溴联苯乙烷、三氧化二锑等为阻燃剂，氢氧化铝为抑烟剂，富含芳烃的抽出油为调和剂，在加热搅拌的条件下，制得了阻燃沥青。
