NOVELTY - Preparing graphene-rare earth double modified potassium magnesium titanate comprises uniformly mixing titanium oxide, graphene and molten salt, and sintering the above mixture, where the mixed molar ratio is titanium oxide : carbide =1:(0.05-0.2), uniformly mixing above mixture, potassium-containing compound, magnesium-containing compound, rare earth compound and molten salt, where the magnesium-containing compound is calculated as magnesium oxide, the titanium oxide is calculated as titanium dioxide, the potassium-containing compound is calculated as potassium oxide, and the rare earth compound is calculated as cerium dioxide in a ratio of (0.95-1.05):1:4:(0.005-0.01), sintering the above mixture by laser sintering with laser power of 500-1600 W, scanning rate of 100-120 mm/minute, and spot diameter of 3-5 mm for3-20 seconds, and crushing the sintered product to obtain the graphene-rare earth double-modified potassium magnesium titanate. USE - The magnesium titanate is useful in friction material (claimed). ADVANTAGE - The magnesium titanate reduces the braking noise caused by friction with the brake disc. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-rare earth double modified potassium magnesium titanate prepared by the above method.
