The technology for construction ceramics based on cold isostatic pressing makes it possible to obtain articles with high values of the required properties. Nonetheless, the use of isostatic pressing is often limited by difficulties related with obtaining shaped articles with fine elements and large length-to-transverse section ratio. The method proposed for isostatic pressing of powders in thermoplastic molds aids in solving this problem. The particularities, advantages, and drawbacks of such molds are examined.
