==性质==
白色针状不吸潮结晶，在空气中稳定。赤热时不失重，结晶较硬。相对密度3.48。熔点840°C。溶于水，不溶于[[氨水]]。有毒！

氟锆酸钾在高温可以被铝还原，得到金属[[锆]]。<ref>黄育夫. 铝还原氟锆酸钾生产高纯锆的新工艺试验研究[J]. 科学家, 2016, 4(5):149-149.</ref>
: K<sub>2</sub>ZrF<sub>6</sub> + Al → Zr + KF + AlF<sub>3</sub>
==制备==
[[二氧化锆]]溶于[[氢氟酸]]后，加入[[碳酸钾]]进行反应，经蒸发、冷却、结晶、烘干，制得成品。
:<math>\rm \ ZrO_2+6HF\rightarrow 2HF\cdot ZrF_4+2H_2O</math>
:<math>\rm \ 2HF\cdot ZrF_4+K_2CO_3\rightarrow K_2ZrF_6+CO_2\uparrow +H_2O</math>

==用途==
用于制取金属[[锆]]、其他锆化合物、镁铝合金，以及生产陶瓷和玻璃。也用作耐火材料、电器材料和电真空技术材料等。
