The invention is about to improve the solid ceramic particle proppant of deep oil and gas well fracturing technique, the solid proppant composed of crude bauxitic clay fine powder and 6-10wt% manganese dioxide mineral fine powder. The manganese dioxide reacts with the bauxitic clay main material more completely under high temperature, largely reducing glass phase, and beneficial to raise the compactness of the resultant at the same time, able to largely heighten the guide-flow ability. The solid proppant: bulking density 1.65-1.8g/cu cm, apparent density 3.0-3.15g/cu cm, and breaking resistance (SY/T5108-1997) 86MPa not greater than 10%, the maximum able to reach 100MPa not greater than 10%.
