Which type of erupted material is particularly hazardous to aircraft?
ash
What types of material can come out of a volcano?
Lava, ash, smoke, and rock
What is the name light coloured material produced when a volcano erupts?
Ash
What material makes up ash and pumice?
They are mostly made up of volcanic glasses
Why is ash solid material?
Yes because it is not a gas or a liquid and do you seriosly think that it's a plasma.
What is the difference between sulphated ash and residue on ignition?
The only difference between sulphated ash and the residue on ignition is the terminology. The residue on an ignition is sulphated ash.
What is difference between sulphated ash and heavy metal?
Not so important differences: Heavy metal ash (but also in general ash): ash resulting from the calcination of a material; practically is a mixture of oxides. Sulphated ash: the sample is initially treated with sulphuric acid and the residues are calcined.
Why add sulphuric acid in sulphated ash?
sample dicompose purpose........
Why used sulfuric acid in sulphated ash test?
To convert the inorganic metals into metal sulphates very easily.
What is difference between sulphated ash and residue on ignition?
in both the tests the main motto is to determine the inorganic metal contents.
Natural bow material?
Ash or Yew.
What is the formula of ash?
Generally ash is a mixture of oxides and silicates; the composition depends on the burned material.
What is sulphated ash?
The sulphated ash test is an analytical test for determining the inorganic content of a sample by weight. The sample ( usually 1g) is accurately weighed into a platinum, silica crucible that has been previously ignited, cooled and weighed. The sample in the crucible is then subjected to sulphuric acid (usually 1mL) and charred at a low temperature without causing ignition of the sample until there are no more white fumes given off. The crucible with the charred sample is then placed in a furnace (temperature is dependent on monograph but typically it can be from 600 to 900 degrees celcius) until all organic matter has been burnt off. The crucible is cooled and re-weighed. The difference in sample weights being the sulphated ash content remaining. Some monographs require the sample to be re-ashed until a constand weight has been achieved. The remaining inorganic matter is typically metal oxides from most samples.
What is is volcanic material or burnt out fuel wood?
Ash
Why do burning anything changes into ash?
Not anything; ash is formed only from non-combustible components of a material.
Why ash is used in cement?
When ash is used in cement it is called pozzolanic cement.Use of ash reduces heat generation in cement.Ash is used as a cement replacement material.
Ash?
Fine material thrown out of a volcano during an eruption.
