摘要
考查了铸造用天然硅砂的矿物晶体形态， 可将其大致分为单晶体和多晶集合体两类。试验结果表明， 单晶体组成的铸造用硅砂具有较高的稳定性和耐用性； 多晶集合体砂粒组成的铸造用硅砂具有较低的稳定性。矿物晶体形态是铸造用天然硅砂的一个重要物理参数。
The mineral crystalline morphology of foundry natural silica sands has been investigated,which can be divided into two groups:single crystal and polycrystalline gather.The results revealed that silica sands composed of single crystal have higher stability and durability,while the silica sands composed of polycrystalline gather have lower stability and durability.Thus,the mineral crystalline morphology of natural silica sand is an important parameter for use in foundry.
