Waste porcelain slurry and application thereof
The invention discloses waste porcelain slurry and application thereof, and belongs to the technical field of ceramic slurry, waste porcelain is rolled and crushed into waste porcelain particles, the waste porcelain particles and deionized water are subjected to ball milling, discharging, drying and sieving through a 500-600-mesh sieve, and waste porcelain powder is obtained; stirring and mixing the waste porcelain powder, the coated silicon nitride fiber, mica powder, a dispersing agent and deionized water to obtain waste porcelain slurry; the reutilization of the waste porcelain is facilitated, and the environmental pollution is reduced; the tricalcium phosphate powder is attached to the surface of the silicon nitride fiber precursor, and the coated silicon nitride fiber is formed after high-temperature degreasing, so that the temperature range of firing of the purple grit mud is increased, and the purple grit mud is prevented from generating cracks during firing. Silicon nitride has good heat resistance, tricalcium phosphate and yttrium oxide are beneficial for reducing the melting point, so that the density and strength of the coated silicon nitride fiber are increased, iron oxide is beneficial for improving the chromaticity of the coated silicon nitride fiber, and application of waste porcelain slurry in purple grit mud is facilitated.
本发明公开了一种废瓷浆料及其应用，属于陶瓷浆料技术领域，将废瓷辊压粉碎成废瓷颗粒，将废瓷颗粒、去离子水球磨出料，干燥，过500‑600目筛，得到废瓷粉末；将废瓷粉末、包覆型氮化硅纤维、云母粉、分散剂和去离子水搅拌混合，得到废瓷浆料；有利于废瓷的重新利用，减轻了环境污染；氮化硅纤维前驱体表面附着有磷酸三钙粉末，经过高温脱脂后，形成包覆型氮化硅纤维，有利于增加紫砂泥烧制的温度范围，防止紫砂泥在烧制时产生裂纹。氮化硅具有较好的耐热性，磷酸三钙和氧化钇有助于降低熔点，从而增加包覆型氮化硅纤维的致密度和强度，氧化铁有助于改善其色度，有助于废瓷浆料在紫砂泥中进行应用。
