Abstract
Ceramic raw materials such as clay, soapstone, or kaolin are purified and rendered more plastic by treatment with sodium or potassium chloride, and particularly with a normal solution of potassium chloride. An acid treatment, for instance with \baN/10\be hydrochloric acid, may precede or follow or be effected simultaneously with the treatment with the salt, and the reaction may be promoted by heat. Coarse impurities such as mica may be first removed by making the clay into a slip with addition of waterglass. Iron and aluminium salts may be recovered from the used washing liquids. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter; the use, for the purification, of any alkali or alkaline-earth metal salt. This subject-matter does not appear in the Specification as accepted.ALSO:The washing of ceramic raw materials such as clay, soapstone or kaolin is effected by means of a solution of sodium or potassium chloride, whereby the materials are purified and rendered more plastic. An acid, such as hydrochloric acid, may also be present. Coarse impurities such as mica may be first removed by making the clay into a slip with addition of waterglass. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter: the use, as washing solution, of any alkali or alkaline-earth metal salt. This subject-matter does not appear in the Specification as accepted.
