摘要： A method of protecting a cathode during the start-up procedure of an aluminum electrowinning cell where the cathode is optionally coated with an aluminium-wettable refractory material and when in use, aluminium is produced thereon. The start-up procedure comprises applying, before preheating the cell, one or more start-up layers in intimate contact on the aluminium-wettable refractory coating which form(s) a temporary protection against damage of chemical and/or mechanical origin to the aluminium-wettable coating; this temporary protection being eliminated before or during the initial normal cell operation. The temporary protection layers may be obtained from at least one pliable aluminium foil having a thickness of less than 0.1 mm and/or an applied aluminium-containing metallization, optionally in combination with inter alia a boron-containing solution, a polymer, a phosphates of aluminium-containing solution, or a colloid that gels while preheating the cell, or combinations thereof.
摘要翻译：一种在铝电解冶金池的启动过程中保护阴极的方法，其中阴极任选地涂覆有铝可湿性耐火材料，并且在使用时在其上制备铝。启动程序包括在预热电池之前将一个或多个启动层紧密接触在铝可湿性耐火涂层上，其形成临时保护以防止化学和/或机械原因损坏铝润湿涂层; 这种临时保护在初始正常小区操作之前或期间被消除。临时保护层可以从厚度小于0.1mm的至少一个柔韧的铝箔和/或施加的含铝金属化物获得，任选地特别地与含硼溶液，聚合物，磷酸盐含铝溶液或在预热电池时凝胶化的胶体，或其组合。

摘要： A refractory boride body or coating made of a boride of titanium, chromium, vanadium, ziconium, hafnium, niobium, tantalum, molybednum and cerium is produced from a slurry of the refractory boride or a precursor in a collidal carrier preferably composed of two more different grades of the same colloidal carrier selected from colloidal alumina, yttria, ceria, thoria, zirconia, magnesia, lithia, monoaluminum phosphate and cerium acetate. The slurry can also comprise an organic additive selected from polyvinyl alcohol; polyacrylic acid; hydroxyy propyl methyl cellulose; polythylene glycol; ethylene glycol, butyl benzyl phthalate; ammonium polymethacrylate and mixtures thereof. The retractory boride body or coated body is useful as a component of aluminum electrowinning cells.
