Bauxite proppant, also known as ceramic proppant, is an engineered material used in hydraulic fracturing (fracking) to enhance the extraction of oil and natural gas from unconventional reservoirs. The most common proppant is sand, but there is growing interest in engineered proppants. Engineered proppants are made from ceramics, typically derived from bauxite, offering advantages such as uniform size and shape, as well as high strength. The ability to strictly control particle size maximizes porosity, thereby maximizing the extraction of natural gas. Sintered bauxite proppants can be widely used in deep wells and high-pressure oil and gas reservoir fracturing treatments. Using high-quality bauxite as the main raw material, it is crushed, finely ground into powder, mixed with various additives, repeatedly kneaded, granulated, polished, and sintered at high temperatures to form the product. The product features high compressive strength, low density, sphericity, good roundness, high smoothness, and strong conductivity. What role does bauxite soil play in making proppant for petroleum fracturing?

Product Application: Ceramic salt cores are primarily used in the casting process of liquid forging aluminum alloy pistons. By forming cavities inside the piston, ceramic salt cores help achieve an internal cooling structure for the piston. Features: High Strength: By adding ceramic additives, ceramic salt cores achieve high strength, enhancing their ability to withstand high temperatures and pressures of aluminum liquid. High Density: Multiple granulation techniques are employed to achieve high density in ceramic salt cores, contributing to the overall quality of the castings. Low Linear Expansion Coefficient: Through innovative sintering techniques, ceramic salt cores achieve a low linear expansion coefficient, reducing the impact of thermal expansion on aluminum alloy pistons. Ceramic salt cores are typically used in the casting of liquid forging aluminum alloy pistons. Compared to traditional salt cores, ceramic salt cores meet the requirements of high-pressure casting processes for salt cores by increasing ceramic additives, using multiple granulation techniques, and innovative sintering techniques to achieve high strength, high density, and low linear expansion coefficient performance.
