可以制玻璃的:SiO2+Na2CO3=Na2SiO3+CO2
SiO2+CaCO3=CaSiO3+CO2
其他资料如下:
石英砂所具有的的物理、化学特性,使得其在航空、航天、电子、机械以及当今飞速发展的IT产业中占有举足轻重的地位,特别是其内在分子链结构、晶体形状和晶格变化规律,使其具有的耐高温、热膨胀系数小、高度绝缘、耐腐蚀、压电效应、谐振效应以及其的光学特性,在许多高科技产品中发挥着越来越重要的作用。
石英砂是重要的工业矿物原料,非化学危险品,广泛用于玻璃、铸造、陶瓷及耐火材料、冶炼硅铁、冶金熔剂、冶金、建筑、化工、塑料、橡胶、磨料等工业。 可汽运,火车运输,水运。工业生产一般为50KG或25KG包装及出口吨袋包装。常用规格:0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm.(mm为毫米单位)。
一、玻璃:平板玻璃、浮法玻璃、玻璃制品(玻璃罐、玻璃瓶、玻璃管等)、光学玻璃、玻璃纤维、玻璃仪器、导电玻璃、玻璃布及防射线特种玻璃等的主要原料; 
二、陶瓷及耐火材料:瓷器的胚料和釉料,窑炉用高硅砖、普通硅砖以及碳化硅等的原料;
三、冶金:硅金属、硅铁合金和硅铝合金等的原料或添加剂、熔剂; 
四、建筑:混凝土、胶凝材料、筑路材料、人造大理石、水泥物理性能检验材料(即水泥标准砂)等; 
五、化工:硅化合物和水玻璃等的原料,硫酸塔的填充物,无定形二氧化硅微粉; 
六、机械:铸造型砂的主要原料,研磨材料(喷砂、硬研磨纸、砂纸、砂布等); 
七、电子:高纯度金属硅、通讯用光纤等; 
八、橡胶、塑料:填料(可提高耐磨性); 

九、涂料:填料(可提高涂料的耐酸性)。



vailable glass: SiO2 + Na2CO3 = Na2SiO3 + CO2
SiO2+CaCO3=CaSiO3+CO2
Other information is as follows:
The unique physical and chemical characteristics of quartz sand make it play an important role in the aviation, aerospace, electronics, machinery and today's rapid development of IT industry, especially its internal molecular chain structure, crystal shape and lattice change law, which make it have high temperature resistance, small coefficient of thermal expansion, high insulation, corrosion resistance, piezoelectric effect, resonance effect and Its unique optical properties play an increasingly important role in many high-tech products.
Quartz sand is an important industrial mineral raw material, non chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries. It can be transported by car, train and water. Industrial production is generally 50kg or 25kg packaging and export ton bag packaging. Common specification: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm is millimeter unit).
1、 Glass: the main raw materials of flat glass, float glass, glass products (glass can, glass bottle, glass tube, etc.), optical glass, glass fiber, glass instrument, conductive glass, glass cloth and special ray proof glass, etc;
2、 Ceramics and refractories: raw materials for porcelain embryo and glaze, high silicon brick for kiln, common silicon brick and silicon carbide, etc;
3、 Metallurgy: raw materials, additives and fluxes of silicon metal, ferrosilicon alloy and silicon aluminum alloy;
4、 Construction: concrete, cementitious materials, road building materials, artificial marble, cement physical performance test materials (i.e. cement standard sand), etc;
5、 Chemical industry: raw materials of silicon compounds and water glass, filler of sulfuric acid tower, amorphous silica powder;
6、 Machinery: main raw materials of casting sand, abrasive materials (sand blasting, hard abrasive paper, abrasive paper, abrasive cloth, etc.);
7、 Electronics: high purity silicon metal, optical fiber for communication, etc;
8、 Rubber, plastic: filler (can improve wear resistance);
9、 Coating: filler (can improve the acid resistance of coating).
