RESUMO:

Waste production in industries has been a recurring concern in recent years. With increasing environmental awareness, several recommendations on waste management have been developed to protect the environment and society, the main one being the minimization of their production. When impractical, the next suggested action is reuse or recycling. In the oil industry well drilling generates large volumes of wastes that are deposited in landfills and accumulated. The mineral extraction industry, in the same way, generates large amounts of waste in the preparation of the product for commercialization: about 70% of the extracted volume. Several authors have studied the incorporation of these residues in the development of new products, mainly ceramics, due to the heterogeneity of their composition. This work, therefore, has the objective of developing a glass ceramic from petroleum drilling residues from the potiguar area, and tailings from the processing of the Caulim of the city of Equador / RN. As an innovative proposal, the residue samples were characterized in order to obtain the best formulation based on SiO2-Al2O3-CaO-Na2O-K2O-MgO composition. The mixture of 10g of gravel, 5g of kaolin and 2.5g of Na2O was then melted at 1500ºC for 1h, obtaining a glass afterwards subjected to FRX, TG-DSC and DIL analysis to support the preparation of the glass ceramic. Vitreous powder pellets were produced and sintered at 800 ° C for 30 minutes to study the densification and crystallization of the material. The structure and properties of the glass ceramic were analyzed by XRD, FRX, TG and MEV, which proved the viability of the residues in their production.
