Exploitation of siliceous following problems compared with foreign: A, narrow the scope of application of the limitations in the vast majority of applications siliceous materials, the other in agriculture, there is a small amount of mechanical and electrical, chemical and environmental applications. In addition to these four overseas departments outside the refractories industry sales, also used in machinery, electronics, metallurgy industry, and its apparent broad application areas. B, less product variety for a particular application area, the variety of siliceous patented product is significantly less than in other countries, to agricultural applications, for example, China's only medium soilless cultivation of flowers, fruit and vegetable fertilizer and three types of proprietary products . And foreign siliceous patented products, including animal washers, soil improvement, many bacteria culture carrier material, pesticides carrier, feed additives and other species, more fully utilize siliceous adsorption, cation exchange properties. Gap in building materials, petroleum chemical industry is also great. C, simple processing method for the direct use of general of siliceous ore and calcined use expansion after use, simple processing method. Abroad is often used for different applications in different processing methods to produce specific grain size, density or expanded to meet the needs of different multiples of siliceous products, their method is relatively advanced processing technology, innovative, diverse refractories, corresponding more to promote its use field broaden and develop new products. D, fine-grained siliceous low utilization rate of the coarse-grained siliceous application has a good foundation, but fine (-0.3mm) silicon utilization is low, resulting in a waste of resources. Particles composed of clay products, general thickness of the particles are more refractory particles less variety, not only to ensure that the density and strength of refractory products, but also improve the thermal shock resistance of refractory products. At the same time, should the particle size adjustments and amendments in accordance with the size and surface quality requirements.
