熔融陶瓷砂(宝珠砂)常用粒度：
8/12、12/20、30、20/40、30/50、40/70、50/100、70/140、140/200等。
熔融陶瓷砂(宝珠砂)的特点
1、 热膨胀率小——熔融陶瓷砂(宝珠砂)受热后的膨胀率是硅砂的 1/5,铬铁矿砂的 1/2,所生产的铸件尺寸精度高，脉纹、裂纹缺陷少，铸件成品率高；
2、 砂粒为球形，表面光滑——使得粘结剂能均匀覆盖且消耗量少，砂子流动性好，易春实，且透气性好；
3、 属中性材料——酸、碱粘结剂均可使用；
4、 耐火度高——减少铸件粘砂倾向；
5、 耐破碎性好——宝珠砂材质致密，抗压强度高，重复使用时破碎率低，减少了废砂排放，有利于环境保护；
6、 性价比高——与锆英砂相比，其价格只有锆英砂20~40%。同时，因砂粒为球形，其表面积小，粘结剂的加入量可减少30%~50%；
7、 应用范围广——水玻璃砂、树脂砂、精密铸造、3D打印及铜、铝件的抛光清理等。
