Abstract

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.
