ClayWikipedia
Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet due to a molecular film of water surrounding the clay particles but become hard brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured but natural clays show a variety of colours from impurities such as a reddish or brownish colour

Effect of distribution patterns of refractory overlayers
Among the options that exist waste reutilization is of high priority from the perspective of green chemistry because it simultaneously reduces the amount of waste and the cost of waste treatment. 1 Waste oyster shell for example is estimated to have about 4200k metric ton production in Taiwan. 2 The high calcium content allows it to be a

Abstract One of the most important elements of furnaces boilers and other heating units is the structure (lining) usually made of silica–alumina basic or special refractories. The basic refractories are materials that are increasingly in demand and whose manufacturing involves necessarily the use of MgO and CaO. In this article the description and characterization of magnesite (MgCO3
