    Abstract: The inventions refers to a method of manufacture of a multilayer ceramic shell mould whereof at least one contact layer, one intermediate layer and several reinforcing layers, out of a wax master pattern or other similar material, consists in performing the following successive operations: dipping in a first slip containing ceramic particles and a binder, depositing sand particles onto said layer and drying said contact layer, in order to form said contact layer, dipping in a second slip containing ceramic particles and a binder, depositing sand particles onto said intermediate layer and in drying said layer, in order to form said intermediate layer, dipping in at least a third slip containing ceramic particles and a binder, depositing sand particles onto said layer, drying said layer, in order to form a reinforcing layer, the formation of reinforcing layers being repeated until obtaining a shell mould of set thickness. characterised in that the ceramic particles of the slips comprise a refractory oxide or a mixture of zircon-less refractory oxides, whereas no layer contains any zircon. Such method is characterised in that the ceramic particles of the slips comprise a refractory oxide or a mixture of zircon-less refractory oxides,

    Abstract translation: 本发明涉及一种制造多层陶瓷壳模的方法，其中至少一个接触层，一个中间层和几个加强层由蜡主图或其他类似材料组成在于执行以下连续操作：浸入 含有陶瓷颗粒和粘合剂的第一滑移剂，将砂粒沉积到所述层上并干燥所述接触层，以便形成所述接触层，浸入含有陶瓷颗粒和粘合剂的第二滑移剂中，将砂粒沉积到所述中间层上，以及 在干燥所述层时，为了形成所述中间层，浸入至少三分之一的含有陶瓷颗粒和粘合剂的层中，将砂粒沉积到所述层上，干燥所述层，以形成增强层，形成增强层 重复层，直到获得设定厚度的壳模具。 其特征在于，所述滑移体的陶瓷颗粒包含难熔氧化物或无锆石难熔氧化物的混合物，而没有层含有任何锆石。 这种方法的特征在于，滑移体的陶瓷颗粒包括难熔氧化物或无锆石难熔氧化物的混合物，
