aChem essay By Ian Diamond (Synthesis of artificial diamonds) Everyone knows Diamonds are hard and beautiful‚ but there are less people known a diamond could be the oldest material. Diamonds are found may be 50 to 1‚600 million years old‚ the diamonds themselves are about 3.3 billion years old. This difference is because the volcanic magma that solidifies into rock where diamonds are found did not create them‚ but only transported the diamonds from the Earth’s cover to the surface. Diamonds

processed material‚ the binder used and the desired end product. Charcoal briquette machine is mainly used for pressing all kinds of powdery and waste materials including charcoal dust‚carbon dust‚ bamboo charcoal powder‚ coke powder‚ hookah dust‚ graphite powder‚ date wood carbon and semi coke powder. The final powder can be in the shape of square‚ ball egg‚ elliptic shape‚ egg shape‚ round orbit‚ cylinder shape‚ bread shapeand pincushion. Fote charcoal briquetting machine is widely used in such fields

The modern steel plant receives low current‚ high voltage power from the generators of the electrical utility company. The purpose of the steel plant primary transformer is to step-down this voltage. The transformer thus provides high current‚ low voltage power for the EAF furnace. Large furnaces with transformers rated at 100MVA or higher is not uncommon. There are usually two stages to this process. The transformer first steps-down the voltage from high to medium levels. There are different

IGCSE Complete Chemistry Notes Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances‚ when mixed‚ particles bounce off in all directions when they collide. This mixing process is called diffusion. It’s also the movement of particles without a force. The smallest particle
