High melting point
Aluminum oxide has a high melting point because it has strong ionic bonds between aluminum and oxygen atoms. These bonds require a significant amount of energy to break, leading to a high melting point. Additionally, the structure of aluminum oxide is a giant ionic lattice, which further contributes to its high melting point.
as all of its molecules are packed closely together and have a strong bond!
Yes, calcium oxide is a solid at room temperature. It has a high melting point of 2,572 degrees Celsius, so it remains in a solid state at typical room temperatures.
No, platinum has a high melting point of 1,768 degrees Celsius, making it one of the highest melting metals. This high melting point is one of the reasons why platinum is valued for its durability and resistance to heat.
The chemical formula of calcium oxide is CaO.

Barium can form both barium peroxide (BaO2) and barium oxide (BaO) depending on the conditions. Barium peroxide is formed when barium reacts with oxygen in excess. Barium oxide is commonly formed when barium reacts with oxygen in limited supply or at high temperatures.
Yes, barium acetate is a solid compound at room temperature. It is a white crystalline solid with a high melting point.
Barium is a solid at room temperature, and has a melting point of 727°C. Barium at room temperature is explosively combustible, especially as powder, due to its extreme reactivity with oxygen in the air. Barium sulfate is used in medical radiology, and barium is used with yttrium in YBCO high-temperature superconducting compounds (yttrium barium copper oxide).
Barium chloride or BaCl2
This element is wolfram (W): 3 422 oC.
Barium hypochlorite is a white crystalline solid at room temperature. It is insoluble in water and has a high melting point.
The melting point of zinc oxide is relatively high, around 1975°C. This is because zinc oxide forms a network crystal structure with strong ionic bonds between zinc and oxygen atoms. The high melting point reflects the energy required to break these bonds and transition from a solid to a liquid state.
Melting point of zinc: 787,15 0F Boiling point of zinc: 1 655 0F
Rust is a compound primarily composed of iron oxide, which has a melting point of around 1,538 degrees Celsius (2,800 degrees Fahrenheit). This melting point is relatively high compared to other common materials. Therefore, it can be said that rust does have a relatively high melting point.
Tungsten oxide (WO3) has one of the highest melting points among metal oxides, around 1473 degrees Celsius. Other metal oxides with high melting points include alumina (aluminum oxide) and zirconia (zirconium oxide).
Tungsten is used in the cathode ray tube (CRT) because it has a high melting point and good thermionic emission properties, which means it can easily release electrons. The thorium oxide or barium oxide coating on the tungsten helps to improve electron emission efficiency by reducing work function and enhancing electron current. This combination allows for better electron beam production in the CRT.
