Produção de porcelana de ossos e caracterização de suas propriedades técnicas Production of bone porcelain and characterization of its technical properties

Abstract

A porcelana de cinza de ossos é amplamente aceita e alcança alto valor de mercado, entretanto, sua produção ainda é pouco difundida, de modo que sua fabricação e pesquisa são restritas a poucos países. Sendo o Brasil grande produtor de gado, apresenta grande potencial para a reciclagem de ossos, podendo-se encontrar aplicação destes em materiais cerâmicos. Neste trabalho foi feita uma análise comparativa das características técnicas entre uma formulação de porcelana obtida com cinzas de ossos conforme a receita tradicional inglesa e uma formulação de porcelana tradicional. Os resultados mostraram que a sinterização de porcelana de cinzas de ossos requer cuidados extras em ciclos rápidos de queima quando comparada à porcelana tradicional, devido a um menor intervalo de gresificação. No entanto, a maior resistência mecânica e as qualidades estéticas, destacando-se a elevada alvura, fazem desta porcelana bastante atrativa em termos de potencial de aplicações industriais.Porcelains from bone ash are widely accepted and present high market value, however, their manufacture and research are still restricted to few countries. As a great producer of cattle, Brazil presents great potential for the recycling of cattle bone into ceramic materials. In this work, it was realized a comparative investigation of technical properties of a typical porcelain composition manufactured from bone ash according to English traditional composition and a traditional porcelain. The results revealed that it is more difficult to sinter bone porcelain in fast firing cycles, once it showed shorter firing intervals compared to traditional porcelains. However, the higher mechanical strength and better aesthetic qualities, especially its whiteness, make bone porcelains very attractive materials in terms of industrial applications potential.
