The invention provides a silicon nitride microcrystalline plate and a production process thereof, and relates to the technical field of silicon nitride microcrystalline plate production processes. According to the silicon nitride microcrystalline plate and the production process thereof, the composition of the silicon nitride microcrystalline plate contains S < i > Cgt; the preparation method comprises the following steps: taking 98% of coarse, medium and fine particles S < i > C and industrial silicon powder containing S < i > of more than 98%, particles of less than 10 [mu] m and the maximum particle of not more than 20 [mu] m as raw materials, and S1, preparing S < i >-containing Cgt; the preparation method comprises the following steps: proportioning the following raw materials in percentage by weight: 98% of coarse, medium and fine particles S < i > C and industrial silicon powder containing more than 98% of S < i >, less than 10 [mu] m and not more than 20 [mu] m to obtain a mixed material; on the basis of controlling raw materials required by production of the silicon nitride microcrystal plate, each production process flow of the silicon nitride microcrystal plate from burdening, mixing, forming, drying, sintering and detecting is strictly controlled, so that the sintering difficulty of the silicon nitride microcrystal plate is reduced, unstable variable factors existing in the production process are also greatly avoided, and the production efficiency of the silicon nitride microcrystal plate is improved. The yield increasing benefit and the energy-saving and consumption-reducing benefit are favorably improved.
