High-purity amorphous quartz ceramic and preparation method thereof
The invention discloses high-purity amorphous quartz ceramic and a preparation method thereof, and the high-purity amorphous quartz ceramic comprises the following raw materials in parts by weight: 80-90 parts of high-purity amorphous fused quartz, 0.5-1 part of fused zirconia, 4-5 parts of zirconium-containing silica fume, 2.5-3.5 parts of white dextrin and 4-8 parts of a binding agent. According to the high-purity amorphous quartz ceramic, the content of pure silicon dioxide can reach 99% or above, the purity is high, and in some special use scenes such as the top of a glass molten pool, impurities cannot be introduced into a high-temperature solution, and the quality of a product cannot be reduced; the normal-temperature compressive strength of the high-purity amorphous quartz ceramic can reach 100 MPa or above, the strength is greatly improved, the wear resistance is greatly improved, and the service life can be greatly prolonged; the thermal shock performance (1100 DEG C, water cooling) of the high-purity amorphous quartz ceramic is more than 100 times, the rapid cooling and rapid heating resistance is greatly improved, and the application scene is wider.
本发明公开了一种高纯非晶态石英陶瓷及其制备方法，包括以下重量份的原料，高纯非晶态电熔石英80‑90份、电熔氧化锆0.5‑1份、含锆微硅粉4‑5份、白糊精2.5‑3.5份、结合剂4‑8份；本发明高纯非晶态石英陶瓷纯度二氧化硅含量可达99%以上，纯度高，在一些特殊使用场景，比如玻璃熔池顶部等部位，不会给高温溶液引入杂质，降低产品的品质；本发明高纯非晶态石英陶瓷常温耐压强度可达100MPa以上，强度大幅度提高，耐磨性能大幅度提升，使用寿命可以大幅度延长；本发明高纯非晶态石英陶瓷的热震性能（1100℃，水冷）大于100次，耐急冷急热的性能大幅度提升，使用场景更加广泛。
