MnTeMoO6 crystals have been grown by the top-seeded solution growth method. The hardness, density, specific heat and chemical stability of MnTeMoO6 crystal were measured and analyzed. The actual density of MnTeMoO6 crystals are slightly larger than 5.0g/cm-3. An average Mohs hardness of about 4.5 is presented in MnTeMoO6 crystals, indicating the crystal is easy to cut and polish. The hardness and actual density of MnTeMoO6 crystals increase with the crystal quality, and the crystal with the smallest hardness and actual density has the poorest quality. The specific heat was measured to be 0.41-0.55 Jg-1K-1 over the temperature range of 20-300 . The chemical stability measurements indicate that the MnTeMoO6 crystal has an excellent chemical stability and is resistant to diluted hydrochloric acid and diluted nitric acid.
