| Abstract: | Calcium Oxide is an excellent refractory material and as per Ellingham diagram is the most stable of all the oxide materials used as refractory. Plenty of pure raw materials containing calcium oxide are available in nature abundantly. The material at present is not or rather cannot be used as a refractory material owing to its extreme hydration tendency in atmosphere. Once the hydration resistant calcium oxide is available the same can be used for developing various refractory products for particular areas of applications in metallurgical industry. The process of making calcium oxide hydration resistant through sintering or fusion either takes a lot of time or is not techno-economically viable. Hydration resistant calcium oxide with low porosity can be developed in a moving bed plasma reactor in a span of 1-3 minutes. Proper control of particle size distribution, controlling the plasma parameters and suitable additives can achieve the same. |
