Manganese Boride Powder

MnB powder is considered a potential corrosion resistant material due to its high hardness, high wear resistance and corrosion resistance. Manganese boride powder with a ReB2 type (space group P63/mmc) structure can be very hard. There are many methods for synthesizing transition metal borides. For example, Nb-B compounds were synthesized by high temperature self-mixing synthesis (SHS). Mechanical alloys and heat treatment were used in the synthesis of the Cr-B and Mo-B systems. The arc fusion technique was applied to the synthesis of the Mn-B system. However, it may take a week or two of synthesis to synthesize MnB powder and the high sintering temperature was a drawback in the previous synthesis process. With the above methods, it was difficult to obtain single-phase metal borides in a short time. Pressure is an efficient tool for synthesizing new and metastable materials and significantly alters reaction equilibriums. Pressure control allows for a variety of properties to be achieved quickly and cleanly, which can lead to mess, phase separation and other expected effects. Also, the high pressure could help lower the reaction temperature. Pressure optimization is a useful tool to find new solid-state metastable materials with excellent properties, such as superhards, chemical aggregates, etc. In this work, we tried to synthesize high-pressure, high-temperature (HPHT) MnB2-type ReB2, and study the reaction behavior of the Mn -B system and synthesize different types of Mn-B compounds in HPHT. The treatment temperature, holding time, holding pressure and mixed boron to manganese atomic ratio for the synthesis will be described in the following article. The preferred orientation of Manganese boride powder should be a mixed B/Mn atomic ratio.
