Abstract
The article highlights the results of the research performed on refractory composite ceramic material based on ZrB2–ZrO2–B system obtained via hot pressing method. At temperature of 1750 oC material with density of 3.8 – 4.6 g/cm3 was obtained. Testing the material for erosion resistance in high speed gas flow at the temperature of 2200 С revealed average ablation of 2%. Microstructure research prior and after the test was conducted
