CERAMIC PASTES HAVING A NON-STANDARD FORMULATION WITH A PHOSPHOROUS CONTENT GREATER THAN 2 % BY WEIGHT, THE PREPARATION METHOD THEREOF AND THE ADVANTAGES OF SAME

摘要

Unconventional-formula ceramic pastes with a phosphorus content of over 2% in weight. Method of production and the advantages it provides. The purpose of the invention is the preparation of unconventional-formula ceramic pastes by the use of phosphorus compound plasticizers and flux. These phosphorus compounds are mixed with mainly degreasing materials, reducing their fusion temperature and providing them with the plasticity required for the forming of the ceramic piece. This formulation makes it possible to improve the physical-chemical properties of the pastes: water absorption, whiteness, etc. Similarly, it optimises the kilning cycles, obtaining satisfactory sinterisation levels at lower temperatures and kilning times (porcelain-like stoneware at 110 DEG C). Consequently, the formulation of these unconventional pastes with the improvements introduced in the product and in the manufacturing process is hereby claimed.
