摘要：The research results show that,the eolian sand particles have irregular shapes and the main chemical components are silica and alumina,accounting for about 98%of the total.And the main phase is quartz and feldspar in room temperature.The size range of aeolian sand particles is from 100 to 415 m,and the larger the particles are,the higher the sintering temperature will be.three different particle size of 60-80,100-120 in aeolian sand required sintering temperatures of 1200℃,1250℃respectively.The size of aeolian sand particles has the greatest influence on the performance of ceramics,the porosity,water absorption rate and seepage rate of ceramics prepared with small particle size are the lowest,while those of large particles are the opposite.The forming pressure has a great influence on the ceramic voids,but the hardness of other ceramics is not great.
