The invention relates to a light sintered microcrystalline plate and a sintering process thereof. The sintering process comprises the steps of glass particle preparation, ball milling classification, material distribution, sintering crystallization, cold processing and the like. The material distribution comprises a first groove and a second groove which are used for fully paving the glass particles on the fire-resistant mold, the second groove is formed in the bottom of the first groove, the depth of the first groove is 5mm-20mm, the depth of the second groove is 3mm-40mm, and the particle size of the glass particles in the first groove is different from that of the glass particles in the second groove. The method has the beneficial effects that the glass solution is adjusted to be prepared from 40%-70% of SiO2, 8%-20% of CaO, 4%-12% of MgO, 5%-20% of Al2O3 and 2%-8% of Na2O, then the glass solution is subjected to water quenching, and glass particles obtained through water quenching are screened and distrib
