Desenvolvimento de porcelana (Bone China) a partir da Caulinita amazônica e ossos bovinos calcinados

Abstract

The consumption of goods and services has been growing more since the 17th century and this generates waste without the total exhaustion, thus producing solid waste. Some of these waste can still be used by some industries, such as the ceremic industry, which can incorporate materials as substitutes that reproduce the properties of a product or improve them. Bovine bone, a residue of animal origin, can be reused as substituents in porcelain, known as bone china. Although, the method of processing this ceramic is quite usual in several countries since the 60’s, in Brazil, it is not very known, even though it has a great production point due to being one of the largest exporters of beef in the world. In this study was made analyzes of XRF, XRD, DSC, TGA/DTA and studies of ceramic and technologic processing with the aim of developing porcelain using calcined bovine bone and kaolinite found in the Amazon region from three types of formulations with heat treatment at 1180, 1210, 1240 and 1270ºC. There was a strong influence of quartz, present in the Amazonian kaolinite, which affected the flexural strength of the proposed material, however, even so the results were relevant and achieving the object of producing porcelain using bovine bone and Amazonian kaolinite.
