The invention discloses a domestic ceramic with high toughness. The domestic ceramic comprises, by weight, 43-47 parts of china clay, 30-34 parts of kaolin, 8-12 parts of knar clay, 13-15 parts of quartz stones, 10-13 part sof spodumene, 14-17 parts of kyanite, 4-7 parts of sillimanite, 2-5 parts of silicon nitride powder, 1-3 parts of beryllia powder, 0.5-2 parts of iridium oxide powder and 1-2.5 parts of magnesium oxide powder. The invention also provides a production method of the domestic ceramic with high toughness. Cooperation of all raw materials of the domestic ceramic makes the domestic ceramic have the advantages of improved toughness, good bending strength, facilitation of reduction of the damage probability in the production, transportation and use process, and good market prospect.

The invention discloses a composite high-strength Nixing pottery material which is characterized by comprising, by weight, 3-6 parts of east mud, 3-6 parts of west mud, 2-3 parts of clinker after calcination of Nixing potteries, 5-9 parts of zinc oxide, 0.3-0.6 part of serpentine, 0.6-0.8 part of spodumene, 4-7 parts of fine silicon carbide powder and 2-4 parts of tungsten molybdenum rare earth alloy powder. Silicon carbide is added into the Nixing pottery material, so that a forged green body has high hardness, thermal shock resistance and an excellent heat conductivity coefficient, smaller heat stress is applied onto the green body in the heating or cooling process, and the green body has excellent abrasion resistance by a sprayed tungsten molybdenum rare earth alloy.

The invention discloses mineral ceramics and a preparation method thereof. The mineral ceramic comprises the following raw materials: potassium feldspar, silicon dioxide, diopside, spodumene, medicalstone, albite, Quartz, bentonite, kaolin, volcanic rock and clay. The mineral ceramic is not only natural, nontoxic, harmless, tasteless, energy-saving and environment-friendly, but also can change daily drinking water into alkalescent water, thereby improving the physiological effect and health effect of water on human bodies. The preparation process is simple, is beneficial to production and manufacture, and has better market promotion value.

The invention relates to the technical field of mineral separation, in particular to a comprehensive utilization method of pegmatite containing tantalum, niobium, cassiterite, feldspar and spodumene. The comprehensive utilization method of the pegmatite comprises the following steps: crushing and grinding raw ore, and then carrying out flotation, magnetic separation, reselection, concentration, dehydration, precipitation and clarification combined mineral separation process, so that valuable mineral resources such as mica, tantalum-niobium ore, cassiterite, feldspar, spodumene, building material sand and the like contained in the pegmatite can be recycled; the method has the advantages that the method is simple in process, high-quality recovery of spodumene concentrate and feldspar concentrate products and the like can be achieved, the comprehensive recovery utilization rate is high, nearly zero emission of tailings and tail water can be achieved, the method is suitable for large-scale production and application, and stable beneficiation indexes can be kept.
