NOVELTY - Graphene/quartz glass block body preparation involves weighing 5-10g of quartz glass powder. The obtained quartz glass powder is kept in a beaker. The obtained quartz glass powder is added with 200-450ml solvent. The obtained mixture is kept in a cleaned ultrasonic cleaning apparatus. The obtained mixture is dispersed for 20-45 minutes. The obtained mixture is added with 1-15ml deionized water. The obtained mixture is stirred in a magnetic stirrer for 6-12 hours. The obtained mixture is added with deionized water. The obtained mixture is dried at 50-80 degrees C for 12-24 hours. USE - Method for preparing graphene/quartz glass block body (claimed). ADVANTAGE - The method enables to prepare graphene/quartz glass block body in a simple and cost-effective manner, and has high toughness and increased conductivity. DETAILED DESCRIPTION - Graphene/quartz glass block body preparation involves weighing 5-10g of quartz glass powder. The obtained quartz glass powder is kept in a beaker. The obtained quartz glass powder is added with 200-450ml solvent. The obtained mixture is kept in a cleaned ultrasonic cleaning apparatus. The obtained mixture is dispersed for 20-45 minutes. The obtained mixture is added with 1-15ml deionized water. The obtained mixture is stirred in a magnetic stirrer for 6-12 hours. The obtained mixture is added with deionized water. The obtained mixture is dried at 50-80 degrees C for 12-24 hours. The composite powder is prepared by taking modified quartz glass powder. The obtained modified quartz glass powder is added with 200-500ml deionized water. The obtained mixture is stirred for 45-120 minutes. The suspension liquid is prepared by taking 20-100mg graphene. The obtained graphene is added with 200ml deionized water. The obtained mixture is oscillated for 45-120 minutes. The obtained suspension liquid, composite powder and modified quartz glass powder are added slowly. The obtained mixture is extracted and kept stand for 10 minutes. The obtained mixture is filtered. The obtained filtrate is dried at 60 degrees C for 24 hours. The obtained product is sintered at 1200-1400 degrees C and 20-40 megapascal pressure.
