| Description: | The subject of invention is a process of hydrophobization of ceramic powder by application of a thin organic coating onto ceramic powder particles in a water suspension intended for injection moulding. In the process of hydrophobization of ceramic powder by application of an organic coating in a water suspension, a water suspension of ceramic powder is prepared, to which from 0,1 to 2 wt. % of carboxylic acid salt is added. Then the suspension is homogenized and the liquid evaporated during stirring. The dried out powder is heated at a temperature above 90 degrees Celsius for at least 10 minutes. The hydrophobization of ceramic powder enables the preparation of a powder which does not get moist in a humid environment as well as the preparation of paraffin suspensions of ceramic powder with a higher powder content and low viscosity not affected by the presence of moisture in the environment. |
