Abstract:
     The present invention relates to a cheap and safe powder of firecracker and fireworks, in which the potassium chlorate (or potassium nitrate, or mixture of potassium chlorate, potassium nitrate and potassium perchlorate) and dried wood powder are contained. It is characterized by its ingredient weight ratio: 0.8-1.25 for the former and 0.30-0.40 for the latter. The invented formula doesn't contain sulfur and carbon powder, so that its cost is reduced. Its fire-cracking quality is good and its cracking rate is up to more than 98%.
